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. ”
