Takes about a minute and it's in the welcome post to the CNET Laptop Troubleshooting forum. Link follows.
I have problem with my dell 1525. After a full battery discharge, I plugged the power and tried to turn it on. All the lights turn on, but after a second it goes silent and I cannot see anything on the screen even the dell logo. Please someone to help me.. I am in the middle of exam session and I need it.. asap.
I also tried to remove the battery and the power cord, pressed the power button for 30sec, doesn't help.
Later today I will try to remove the RAM and then install it one by one to see if the problem may be caused by bad RAM , but I doubt that this is the solution.
