Re: Lenovo T430 Battery will not charge

Maybe try leaving it in the BIOS setup screen overnight and see if it manages to reset the battery status?

Sure it's worth a try - what, exactly, would that do?

My best guess is that either a power transistor has blown.  There is a fuse also, but fuses usually don't blow without someting else happening.

richk,

 

Thanks for your feedback, you're probably right. Although i don't have a meter or scope handy to check any of the components. Know and good service folks in the Himalayas? =P

 

Thanks for everyone's input!

Re: Lenovo T430 Battery will not charge

Hey everyone on this thread:

 

I never managed to sort out this issue, but have been using the laptop (sometimes with the battery, sometimes without) for the better part of the past year. I even bought a replacement battery - no change in behavior.

 

An update: at some point, the laptop began charging erratically. I'd plug it into AC and it would be charting-notcharging-charging-notchargin on a few second cycles. (A nice symptom of this was the screen brightness cycling rapidly between bright and dim as the machine switched the display mode based on the charge mode. Fun stuff). Sometimes, something would stabilize and the machine would charge successfully and relatively stably (~15 min of charge, 1 min of not charge, repeat. Or something like that). And i'd get back to a full charge. It seemed much more likely to charge stably on 110V AC rather than 220, but that may have just been coincidence.

 

The other day, the three hooks that hold the battery into the machine fell off (due to a poor super-glue job after an earlier trauma - my bad...). Soon after, the battery stopped its erratic cycling and now refuses to charge (again). Does anyone know if the physical hooks are a part of some circuit that helps the machine know if the battery is present? The laptop still runs on battery (it is taped in with duct tape for the time being) but will not charge. Any thoughts or ways to circumvent this problem?

 

Thanks, yall've been great.

aaron

Having this exact same problem (intermittent charging) did you find a solution?

I have the same problem! Now solved.

 

step1: switch off your T430U, unplug the power. 

step2: opend the back plate

step3: disconnect, unscrew and take out the battery

step4: press the power button and hold for 5 second to release the static, release it, wait for 1 second and do it again. Repeat this step for 5 times.

step5: put the battery and back plate back on. 

step6: put the power cord back on.

 

Congratulation!! YOU GOT THE POWER...
