Recently I pressed the power button on my Dell CPx and the lights came on, flashed a time or two and then it shut off. Now, this is with it plugged in. I tried it with a full battery and it did the same thing with the exception that it didn't shut off, it locked up without running and I had to pull the battery to turn it off. I have seen quite a few posts, blogs, and even a bunch of machines that people are selling on ebay that do the same thing. SO, this is obviously a common issue. HOWEVER, I am stumped as to how to fix it. I have tried a working motherboard from my other CPx, another hard drive, ram card, power source, battery, and nothing has worked.
The Dell people kept telling me it's the motherboard but yet everytime I put a good one in it still didn't work...they still told me to buy a damn motherboard! AAAGGGHHH...I have tried applying pressure to the motherboard as some have stated and still nothing. HEEEELLLLPPPP PLLLEAAASSEEE!!
