HP Compaq NC8430 Laptop Battery Question And Answer
Tell me please, should I remove the hp compaq nc8430 battery if the notebook is on AC mainly and just about once or twice a week on battery power?
And some other essential questions:
1) As I know, full discharge of Li-Ion battery is harmful for it – so I think that 3% charge shown by Windows or HP laptop Battery check is about 20% of real, physical charge-so full discharge is impossible- am I right?
2) When I turning my notebook off for the night time, I unplug the hp compaq nc8430 charger off the AC too – is it right?
3) So, when the notebook is off or hibernated it shouldn’t consume any power, but when I turn on the notebook after night – the charge level is not full – (I guess that that it’s a normal physical process somthing like internal resistance or else) – but when the AC is back, the battery begins charging – so if this miserable charge counts by the hp nc8430 battery controller as a new lifetime charging cycle or not?
4) Maybe it is more reasonable to keep the notebook always on AC without removing the battery and the controller will switch the charging device off when the battery doesn’t need any more of charge? But wouldn’t it decrease the battery’s total capability faster?
5)Is it important – how many percent charge left in laptop battery when I begin charging it? Or I should discharge it by the time the notebook switches off and can’t start?
Maximum compaq nc8430 battery life results from keeping it cool – and at below 50% charge when not in use. When it’s in the laptop, it should chage to 100% and may remain warm after charging as a result of heat from the machine itself. So the answer is yes – except that if you need to use it on battery power a couple of times a week, you’ll need to remember to reinsert it to get it fully charged before relying on battery power.
1) The battery will automatically stop itself from discharging at a “safe” voltage.
Full discharge is not impossible – it will happen but very slowly over time if the hp compaq nc8230 battery is stored – due to natural discharge internal chemical reaction and the fact that it is powering its internal electronics
2)Unplugging the ac adaptor is fine as a safety measure, (possible fire or night-time lightning strikes to the power cables) but is not otherwise necessary . If you don’t have a battery fitted, then auto wake-up (eg for incoming fax) won’t of course be available
3. Yes – there is small power consumption on hibernate, from the battery if ac power is unavailable. It’s still connected to the power arbitration circuitry. But the small recharge does not to my knowledge count towards the lifetime cycle count.
4. Personally, I think the fact that the 8510p battery is held in a full state of charge and kept warm will have a greater effect on its life.
5. A properly working battery will measure input and output watts, keeping track or and reporting its charge state. With many short and shallow discharge cycles, its knowledge of its charge state will drift from reality but will otherwise not do any harm. A discharge to 5% or less while working normally follwed by a full recharge should recalibrate the hp 8710w battery. There is no need to discharge to the switch-off and can’t restart stage, although the deeper the discharge, the more accurate should be the calibration.
Having said all of that, it only takes one cell to fail – or a problem in the battery’s internal control system – for the battery to fail completely – and one of these events is more probable than an end of life on cycle count. Consequently, in your position of needing battery power a couple of times a week, I wouldn’t bother taking it out at all – unless your machine keeps it unduly warm.

How to repair a battery that can’t be chargering anymore
How to repair a battery that can’t be chargering anymore?
Sometimes you CAN “rejuvinate” a rechargeable dell xps m1530 battery that doesn’t want to take a charge anymore. You first need to have a basic understanding of WHY the battery is not taking the charge in the first place.
As a battery is used/charged/recharged, it develops little “hairs” of chemical that create an electrical link between the positive and the negative parts inside. This is, in effect, a short circuit inside the battery. If you are trying to recharge the battery, it appears to be charging, but once you take the charger off, there’s still no juice available. This is because of this “short” inside the battery.
I had four rechargeable laptop batteries for an old laptop, and this procedure worked just fine on them. Just note that this does NOT work every time. In my opinion, for every 10 batteries you ‘rejuvinate’, you may end up tossing 3 of them in the garbage! But then, what have you got to lose?
Basically, you will be “burning” out those little “chemical hairs” with a reverse charge.
You will need access to an automotive battery, and a pair of booster cables. You will need to determine the polarity of the dead vgp-bps2c battery …. Which is the positive tab, and which is the negative one on the battery?
Please note that I am NOT RESPONSIBLE for injury or damage to anything! You do this at your own risk. Read the instructions below BEFORE you do any of this!
Do this OUTSIDE, and wear safety glasses and gloves! You can never be too careful!
Put the booster cables onto the automotive battery. The red goes on the Positive (+), and the black on the
Negative (-). Make sure the other ends of the booster cables don’t touch one another. Very similar to boosting someone’s car that won’t start, except we are going to do something different!
Now take your dead hp dv2000 battery, and lay it so you can see the Positive and Negative tabs on it. Best to leave it on the ground, or a flat spot somewhere, rather than hold it in your hands.
What we do next is to apply a very FAST, REVERSE CHARGE from the automotive battery to the dead computer vgp-bps8 battery. The thing to note here is that it is a very quick, fast reverse charge. DO NOT CLAMP the booster cables to the dead battery!
Take the black, Negative (-) booster cable lead, and hold it onto the POSITIVE (+) tab of the dead battery.
Yes, that’s right. It’s backwards. This is half of the job.
Now, take the Positive (+) booster cable lead, and TAP it ONCE on the NEGATIVE (-) tab of the dead laptop battery, and remove it immediately! DO NOT HOLD IT IN PLACE!!!! Your connection here should not be a connection, but just about as long as it takes for you to blink your eye quickly. A QUICK TAP! ….. ONLY DO THIS ONCE!
You may be tempted to do this again, because it might look like nothing happened! DON’T! …. What you just did is apply a very big amount of reverse current to the old dead cell, even though you didn’t see anything. (at most, you may see a small spark). Hopefully, this was JUST enough to burn the ‘chemical hairs’ off, but not enough to damage the cells in the dell inspiron 1520 battery. That’s why it is important not to hold the lead on for more than a 1/10 of a second, and not to try doing it again.
Remove all leads, put your automotive cell and cables away. Try charging your ‘dead’ sony vgp-bps8 battery now. If the above procedure did indeed ‘fix’ your sony vgp-bps9 battery, it will behave JUST LIKE A NEW ONE!
If not, you can repeat the above procedure a couple of times, and try recharging again.
Works for me!
Just be careful. If you are not technically inclined, have someone who IS give you a hand. Just have them read this before THEY do anything either!
I must say this again – you do the above at your own risk, although I never had any problems doing this myself, I can’t be responsible for anyone else!

Dell Vostro 1400 Charger Problems
Question:”My Dell Vostro 1400 charger stopped charging awhile ago, the dell vostro 1400 battery level stays at 74% for some time now. I don’t know why. I try taking out the battery and only use the charger for my Dell laptop and it works. So I thought the problem would be the battery, but getting a new laptop battery doesn’t fix the problem. What should I do?”
Solution:”
I believe your problem is the charger because Dell has a build in mechanism to make sure the laptop ac charger is Dell before allowing it to charge the battery. However, even if the charger is Dell, if the identifier chip inside the charger is broken, the laptop would refuse to recognize the charger and stop charging.
You can follow this Dell’s troubleshooting guide to try to get the laptop to recognize the dell ac adapter. The troubleshooting guide is a bit outdated though, so I don’t know if it applies to your laptop.
http://ftp1.us.dell.com/diags/R66243.htm
If the troubleshooting does not work, most likely, you will have to buy a new dell battery charger since the laptop cannot identify the charger as Dell anymore. However, before you buy a new charger, borrow someone else’s charger to make sure it will charge the laptop and that is the problem for sure. I wouldn’t want you to waste money on a part that is not necessary. Furthermore, seeing that buying a new vostro 1400 battery does not seem to solve the problem, I think that you can return the battery unless you want to keep it.
If you do have to buy a new charger, I would recommend buying one from www.laptop-battery-adapter.com. because they offer lifetime warranty and free shipping to all chargers at a good price. I think it is definitely worth it to consider buying charger from them.”

DELL VOSTRO 1510 Battery Iussue
Question: “I am getting a dell vostro 1510 battery error message in a red cross X “There is a problem with your battery, so your computer might shut down suddenly”. . Battery charge upto 100% but its duration is very low and I have to recharge it again and again after 20 minutes.You upgraded your laptop from XP or Vista to Windows7. You know that the dell laptop battery is good. But now you are getting this error message. What do you do?
I know for a fact that the battery is good. It works fine in Vista, its only about 4 months old, it lasts 2 hours +, and even in Windows 7, it will last for the same time period as it did in Vista.
People have been saying (as well as microsoft) that it is the BIOS and it needs to be updated. Well, I did obtain the latest BIOS from LG, which is dated in 2009, and that didn’t change anything. I’m concluding that it is NOT the BIOS since vista reported the estimated time left of the vostro 1510 battery just fine, even before the bios update, and I have the latest BIOS.
I ran the powercfg -energy command and it says that windows was not able to determine the capacity of the battery, yet if I go and install the LG batery application, it will tell me all the information about the laptop battery.
I even went as far as to try my friend’s battery which is less than 3 weeks old, and it still gave the same error messages.
Please Microsoft, fix this issue, and if you can’t, then give the users an option to take off/disable/supress the blinking X that is on top of the power tray icon, and to remove both the “Consider replacing your battery” and “There is a problem with your battery, so your computer might shut down suddenly” messages so we don’t have to see that every day, since the battery is in fact GOOD and works properly.”
Solution:“dell vostro 2510 Battery management in bios has the possibility to change for 3 values: charge to 50%, charge to 100%, charge maximum. I used the 50% value for testing purpose and could read exact 50% availabilty in the battery status. Then changed to maximum since 100% is bios default. None the better. Now I can read 100% available, and “you should change your battery” while mains is plugged in.
Unplugging the mains adapter gives me the blinking little red cross and the “consider replacing” message.
Since battery drivers are Windows system drivers I won’t find updated drivers on LG’s support site.
I looks like a bad calculation of lifetime/-cycle values of batteries.
By investigating this issue I came across 2 numbers (sorry, I don’t remember if it was Windows or a software tool). These two numbers differed by factor 10. One value was “designed for …” and the other “actual …”. If these values are calculated for a lifetime expectation bei Windows 7, my dell vostro 1400 battery is bad indeed.
I believe this battery tray thing a little bit buggy. I will check with our Microsoft Technical Account Manager next time.”
About “Consider replacing your battery. There is a problem with your battery, so your computer might shut down suddenly.”
The dell vostro 1500 battery life issue on Windows 7 actually dates back to June 2009, according to the forum thread. At the time, Windows 7 wasn’t yet released, but the issue was apparently in both the beta and Release Candidate builds. Apparently the problem wasn’t widespread enough for Microsoft’s quality control team to fix it in time for the RTM build compiled in July 2009, though some users say they’ve only started to notice the issue with the RTM build and that beta builds worked just fine.
Windows 7 was supposed to extend dell vostro 1500 laptop battery life on notebooks, and in almost every case it certainly has. Nevertheless, there are always a few users who have issues. Microsoft’s stance is that the root cause of the issue is related to specific system firmware, meaning it only affects machines with certain BIOS releases. Judging from the forum thread, however, customers disagree with Microsoft’s explanation since the problem appears to affect notebooks from more than just one OEM, and some claim their vendors have informed them that it’s a Microsoft problem. The phrase “class action lawsuit” is mentioned by three different posters so far; users are getting impatient with the software giant as it fails to give a timely official response. Microsoft has sold more than 60 million copies of Windows 7, and it’s not clear what fraction of those owners are having problems with dell vostro 1400 laptop battery life.

Dell XPS M1330 battery not detected
Dell XPS M1330 battery not detected
Question:”Today suddenly my xps m1330 went down and only power LED was started flashing blue/orange. I presumed that it was due to unknowingly power source was disconnected and now battery is also drained.
I checked the power source and restarted the PC. But still the orange LED was flashing. Checked the dell xps m1330 battery status in BIOS and in windows as well: its shows 99% percent charged. So to test the battery I just removed power sources but again PC went down 
Now the situation is that both BIOS & Windows says there is no xps m1330 battery in the system. Where both at this location it was saying that battery was charged 99%. So I just diagnosed system with In built utility and it returns error code 0146 2000-0146. Seems this error is reflection to disk issue.
Still pc is running with AC power source but can not able sustain for a second on laptop battery. I am thinking this should be H/W issue but it would be great help if anybody has solution or workaround for this issue.”
Same Problem:”In my task bar, my battery icon has an X through it and it is telling me that my battery is not being detected. I have no problems with the power cord. And I have not had any error messages, I can run my XPS M1330 off the battery. A diagnostic check says everything is fine, with the pc and the battery. What is going on?”
Solution:
“The error code 0146 and the battery are two separate problems. First the dell xps m1330 battery problem is simple, it’s bad and needs replaced. It being bad can refer to a developed short, a fail safe kicked in, or it’s simply worn out. It is a battery after all, ad they don’t last forever, the more you use them the quicker they wear out. A bad battery causing an issue is vary common with Dell machines, and a false battery reading with a failing battery is also common. The orange flashing battery light is the indicator that the dell xps m1330 battery isn’t working properly, either by fail safe or wear.
The error code 0146 Is from the short test on the hard drive and indicates the a sector is going bad, and eventually the hard drive is going to fail. At this point, your hard drive may last days, or months. Either way, I suggest that you back up all important data, and purchase a new hard drive for the imminent failure. You might even go ahead and set it up, this way you’ll be prepared when it does go, and you won’t have any downtime. ”

dell inspiron 1420 battery not charging
Question:“Dell inspirion 1420 battery not charging adapter not recognized?!?
dell inspiron 1420 battery isn’t charging.. everytime i try to plug it in i get the message “The AC power adapter type cannot be determined. Your system will run slower and the battery will not charge…” I don’t know what to do? My laptop battery is at like 0% so when the charger comes off accidentally my laptop shuts off. I called dell and the guy was a dick. ”
Solution:”
I believe your problem is the laptop ac adapter because Dell has a build in mechanism to make sure the adapter is Dell before allowing it to charge the battery. However, even if the charger is Dell, if the identifier chip inside the adapter is broken, the laptop would refuse to recognize the adapter and stop charging. It seems that your laptop was starting to have the problem when it shows you the message that ac adapter cannot be recognized.
You can follow this Dell’s troubleshooting guide to try to get the laptop to recognize the ac adapter. However, it may not work for your laptop because the guide is outdated.
If the troubleshooting does not work, most likely, you will have to buy a new dell ac adapter. However, before you buy a new ac adapter, borrow someone else’s adapter to make sure it will charge the laptop and that is the problem for sure. I wouldn’t want you to waste money on a part that is not necessary.
If you do have to buy a new ac adapter, I would recommend buying one from www.laptop-battery-adapter.com, because they offer 1 year warranty and free shipping to all adapters at a good price. I think it is definitely worth it to consider buying adapter from them.”
The Dell solution about “Battery Won’t Charge at All”
If your computer runs normally on the AC adapter, but the dell inspiron 1420 battery won’t charge, please try the following troubleshooting steps:
1.Check the Battery and Connections:
2.Swap Bays or Try A Second Computer:
3.Flash the BIOS:
4.Try to charge a second dell laptop battery like your own if possible.
from http://ftp1.us.dell.com/diags/R66243.htm
Solution 2#
When powering on a Dell portable computer, you may receive an error message similar to:
The AC adapter type cannot be determined. This will prevent optimal system performance.
Strike F3 key ( before F1 or F2 key) if you don’t want to see power warning messages again.Strike the F1 key to continue, F2 to run the setup utility.
The system will continue to power on after pressing the <F1> key, but the error message is repeated every time the system is turned on. Also, the system may exhibit symptoms such as sluggish performance or the battery does not charge.
The error message can be caused by any of the following:
- An unsupported dell pa-12 AC adapter is connected to the system or docking station.
- The AC adapter is not fully connected to the system.
- The wall power cord is not fully connected to the AC adapter
- The AC adapter or system’s AC adapter port is damaged.
Ensure a compatible AC adapter is being used.
Dell portable systems have different power requirements based on the processor type, system features, and configurable options. Use the list below to determine the minimum AC power required to effectively run the system and charge the battery.

How to Make a Acer Laptop Battery Last Longer
How to Make a Acer Laptop Battery Last Longer
Save on electricity and get the most out of your laptop when you aren’t plugged in. Here are ten steps to make your BATBL50L6 laptop’s battery last longer.
#Step 1 Dim your screen
For most laptops dimming is a button on the top row that looks like a sun with a down arrow. Press it repeatedly to reach the dimmest screen setting you can still function with.
#Step 2 Turn off programs running in the back ground that you aren’t using
Programs like Itunes, chat programs, Windows Customer Experience Center. All of these take laptop battery life to run, you can extend your battery juice a little bit farther by turning them off. You can even go so far as to set them up not to auto start. This will also decrease the amount of time it takes to start up your computer. If you use an email program like gmail or yahoo you can choose to turn off the chat functions and run on the html setting. You will need to manually refresh to see updates, but you will use a lot less energy.
#Step 3 Run off a hard drive or jump drive rather than a CD or DVD
CDs and DVDs need to spin to function. Spinning takes energy. Hard drives and jump drives don’t spin.
#Step 4 Turn your computer off or to hibernate mode
A “sleeping” computer or a computer on standby is still using quite a bit of energy so that it can start up quickly right were you left off. To conserve the most energy turn it all the way off or set it to hibernate.
#Step 5 Optimize your power settings
Most laptops have a power setting option. Click on the AS07B41 battery icon on your desktop (mine’s in the lower left corner) and you should get the option for several power modes. Choose the one that is called “power saver” or something similar. Some laptops will automatically switch when they aren’t plugged in.
#Step 6 Don’t use sound
Turn the sound off on your computer – it takes up to seven times more energy to play sound than just use the screen of your laptop. If you must have sound, use your headphones. They take far less energy.
#Step 7 Don’t have multiple programs running
When you are working off your Acer Aspire 5920 battery use only one program at a time. Email that refreshes itself constantly can be a big drain on the battery, so close it when you aren’t using it directly.
#Step 8 Keep your temperatures down
A hot computer is an inefficient computer. Use the canned designed to clean electronics to clean out the vents. They are often on the bottom of your laptop. Also if you are using your laptop on a soft surface like a pillow you maybe blocking those vents and your computer isn’t cooling properly. Get a lap board or a large notebook to set your computer on instead.
#Step 9 Defrag your hard drive
You can have a more efficient computer not just in how fast it can do the tasks you give it but in the energy it uses by simply defragging it. Apples tend to not need as much defragging as PCs.
#Step 10 Get a new battery or new computer
Older batteries tend to not hold charge as well. If you have had your battery or used it a lot you may benefit from a new one. There are also lots of new laptops out there that are super efficient. Many are built specifically for use on Acer Aspire 5720 battery alone. If you will be working often without a power source make it a priority in your next computer.

Dell Latitude D620 Battery Not Charging
Question“I have a Dell Latitude D620 Laptop that is only a year and 2 months old. I lost the charger a while back…but there was an extra that came with my computer which I have been using since then. A couple weeks ago my battery stopped working all together (didn’t even have a second of life in it)…so I finally ordered a new dell latitude d620 battery from “Dell.com” for $120 hoping that would solve my problem. It arrived today and I put it into my computer…but it STILL WON”T CHARGE. it’s giving me the message ” Your system will operate slower and the battery will not charge, please contact a Dell D620 AC adapter or higher for best system operation.”
Best Answer“We own 3 DELL Notebook PCs and we got our DELL Latitude D620 last FEB 2007. My other 2 DELL Notebook PCs (Inspiron E1505/6400 and Latitude D800) have 2 Dell original batteries each and based on your problem, if my memory is correct (I use all 3 frequently) but on the bottom of your D620, it cites that the correct DELL AC power adapter I believe for the D620 is PA-10 or PA-12, and my guess is that your original DELL adapter is the samller 65 Watt bec I have gotten that same message before when using the 17″ larger D800 and immediately switched to the larger AC adapter and problem/message went away.
I suspect your DELL error message will be going away too, and if I were in your shoes I would open the CONTROL PANEL and POWER BUTTON WINDOW and watch the % reading which should be climbing.
The only other cause or dilemma might be you bought a replacement dell d620 battery or maybe a used dell d620 battery rather than a genuine new dell laptop battery bec I had a similar battery problem on my 1st Notebook PC (GATEWAY Pentium IV) but luckily I had inquired about refund and return policy before completing the purchase on EBAY, and I might note that I also took 2 screenshots of fact that the compatible battery I received did not charge and stayed at 0% evn after leaving it plugged in overnight.”

Dell xps m1330 battery is reaching the end of its usable life
Dell xps m1330 battery is reaching the end of its usable life
Question:”There’s been a couple of times that I’m using the computer and it will completely black out- even if it still has charge. When I try to start it back up again, it does absolutely nothing. I always thought it just needed time to cool down. That happened to me today the only thing different is I got this message:
“Your laptop battery is able to charge normally, however it is reaching the end of it’s usable life.You can experience a longer operating time with a new battery. You might want to consider purchasing a replacement battery now.”
and apparently this is a common problem after about 12-13 months, you know, right after the 1 year warranty runs out. Seeing as I will probably replace the whole laptop in another year or so, I’d really like to avoid spending $100 on a new dell xps m1330 battery if I can.”
Solution:”You can change the battery yourself easily.
A battery is only good for a certain number of charge / discharge cycles, and after that it is finished.It sounds as if you may be at the end of it’s life.To check the dell xps m1330 battery charge, press and release the status button on the battery charge gauge to illuminate the charge level lights. Each light represents approximately 20 percent of the total battery charge. For example, if four of the lights are on, the battery has 80 percent of its charge remaining. If no lights appear, the battery has no charge.
Also, if you hardly ever use your laptop outside your house I strongly recommended you do NOT buy a new battery, they run up to 200 dollars and you can just take out your old battery, and use power directly from the outlet, this will work fine.
If you PC is under warranty you can obtain a new dell xps m1330 battery for free from dell, just call them. Warranty period is typically 1 year from purchase date.
Now if you want to buy a new battery, it’s probably going to have to be purchased from dell,or buy a replacement 9-cell dell xps m1330 battery just go here: http://www.diggingshop.com/laptop-battery/dell-xps-m1330.htm
and purchase the battery for your PC model.”
