Got this laptop my dad last night. He said the HDD had failed on it and I decided I would fix it. I was able to get it to boot into the bios last night and he looked surprised. Today, I am not able to boot into the bios, or get any fans spinning. I plug the charger in, I get a green charging indicator light. I hit the power button, I get a red thinkpad light. Then both lights turn off and nothing happens. I've hit the reset button and let it charge for 30 minutes after with no luck, disconnected the battery tried with just the power cord with no luck. I disconnected the battery and power hit the power button a bunch of time, as well as held it. did the same with the reset button after those failed attempts.
I'm unable to determine what is causing the failure. I don't see any obvious shorts on the board, and the cmos is unplugged. It is the 4GB I5 model.
any help is appreciated because I am running out of ideas.
