What I suspect is that there's a short in the board and its dead... OR you may remove the board and do a test on it (ie. power it up outside of the case) and see how it goes.
I agree with Tony. The motherboard has failed. Replacements are reasonable. Even another working T500 is fairly inexpensive. You could move your memory and hard drive to the replacement.

But how much is a T400/T500 board these days? And for me the skill might be too high to replace.

According to eBay, $28-$84. This is for the T400's motherboard with AMT, TPM, and the ATI Mobility Radeon HD 3470. Most of the listings' prices tend to lean towards the $28-$37 range, though. The T500's motherboard with AMT, TPM, and the ATI Mobility Radeon HD 3650 ranges from $60-$108.
I do not get the reason why the T500's motherboard costs more than the T400's motherboard, or is that just the prices being unstable as usual?
It isn't, believe me. The hardware maintenance manual will surely help you replace the motherboard in no time. This is heaven compared to disassembling an old Tecra TE2100 without the help of a hardware maintenance manual, well, at least for me it was.
I had an old Tecra which I originally purchased for my daughter and I went for the Toshiba because it was cheaper than a T42 at the time. The hinges broke on the Tecra and it was eventually scrapped.Screamer wrote:This is heaven compared to disassembling an old Tecra TE2100
The thing we love about Thinkpads is that they generally don't break or fall apart but obviously motherboards will fail.

Can also look for complete T500 bases, or complete replacement T500s.
Actually I have spare T500 boards with ATI Radeon 3650 I have no use for, shoot me a PM?
