Re: thinkpad t43 not charging battery
I've seen this before. It's not the AC adapter, it's the circuitry inthat corner of the Thinkpad that routes power off the charge the battery. It might be just a fuse, but it may be that portion of the board is a goner...

Check fuses one by one, the locator is available here:

Re: thinkpad t43 not charging battery
Hello - I stumbled across this post and was happy to see it's relatively recent. Hoping to get some help with the same problem...
I have a T41P. Originally the battery would not charge and the battery status light would constantly flash amber while plugged into AC. The battery would never get charged - 0%. I received a new battery today and placed it into the machine. With the new battery, while powered off and AC plugged in, the battery light was a solid amber so I thought "good sign". I let it charge over night but was surprised the next day the battery was still amber. I powered the system up and the battery tool displayed a 53% charge. Upon removing the AC, the percentage went down, however, plugging in the AC wouldn't charge the battery.
I've disassembled the unit and checked the fuses found in this link: http://nickpaton.fireflyinternet.co.uk/ ... 0Fuses.pdf but none of them seem to be blown. I'm obviously missing something but not sure where to go from here.
If it helps - I know my son had plugged a power adapter from another Lenovo (Netbook S10) into my T41p. I think the netbook AC is a little higher rating than the T41p so that may have triggered the issue.
Please help...

Re: thinkpad t43 not charging battery
The S10 unit supplies 19V.
Your T4x only requires 16V.
You blew it (literally).
Unless you are an expert in problem tracing and SMD soldering, you need a new motherboard

Re: thinkpad t43 not charging battery
Continually flashing amber is a dead battery. Keep it because you may be able to get it re-celled. I left several on for 3 days and they're dead all right...
Deeply discharged good batteries can take 24+ hours to fully recharge.
And yes your main board is blown You have to be careful with this, especially if you have different generation machines.

Re: thinkpad t43 not charging battery
Blinking amber light that doesn't go away may also point to a damaged/dead charging circuit...

Re: thinkpad t43 not charging battery
Correct, but if two of your batteries do this on the same thinkpad but 4 batteriess eventually go solid amber then green, those two batteries are dead and your charging circuit is good!ajkula66 wrote:Blinking amber light that doesn't go away may also point to a damaged/dead charging circuit...
