NB500-108 Battery charging stops at 97%, led light never turns into green
Posted: 08-May-2012 14:03

I have a Mini-Notebook, NB500-108, running Windows 7, and it never had battery issues until now.
For some reason, battery stopped charging at 99%, then at 98% and now at 97%.
Tray icon says "plugged in, charging" but it never reaches 100%.

Besides that, the led light never changes from orange to green, like it used to do before.
That is annoying because I can't see if battery is totally charged when the machine is turned off.

I've already tried a lot of suggestions in order to recalibrate battery:
1. Flashing BIOS;
2. Uninstall/disable Microsoft ACPI-Compliant Control Method in Device Manager;
3. Full discharge/full charge;
4. Half discharge/full charge;
5. Removed the battery and pressed power button for 10, 20, 30 seconds...;
6. System restore;
7. Same beahaviour with a Linux live pen.

None of this worked. Any comments on this, Toshiba Support?
Thank you in advance.

Toshiba Support? This is a user-to-user forum dude… you will get some comments from community members

I think it could be a faulty battery…since lithium batteries would start losing the own performance after being charged for 400-500 times, I would assume that your battery is affected… it’s just a theory but I think it’s worth to test a new part

Oh, ok, community members

Thank you, MasterG.
I really hope it isn't a battery fault because it has been very well treated and I can't complain about its performance, it's still great after 1 year and a half of use. Let see if this changes in the next days...
Meanwhile, other suggestions would be very appreciated.

With the help of a software named Battery Care, I can see three variables:

X = Designed Capacity
Y = Total Capacity
Z = Current Capacity

The thing is: Y never changes. It has stopped decreasing.
That's why Z (current capacity) never matches Y (total capacity).
And I can't find a way to reset the battery total capacity value.

Auto-fixed after some partial discharges/recharges (not full discharges, it was not necessary).

Thanks for sharing...seems that simple battery calibration helped to solve this...
