Everytime I boot it, it runs for a few minutes trying to boot and then it shutsdown completely (no beeps nothing). Once it does that, I can't seem to boot it up again using the power button, unless I were to take the power cord and the battery out and plugged both or one of them back in.
It then starts up for a few minutes and then goes through the same cycle as described above.
It's frustrating because I can't even get it to boot up to the diagnostics partition to try and see what's wrong.
It is out of warranty. I had sent it in to Lenovo last year (cost me $400) and they apparently replaced the motherboard. It worked fine for a couple of months and then started having problems again.
Any suggestions or ideas on how to fix this will be appreciated.
