My laptop was working fine last night, I hibernated it and went to sleep. Got up, pressed the power button. The power light comes on for 4 seconds and the hdd light blinked a few times, then it turned off for a second then repeats the process. The only way to stop this process/power down is to remove the AC and take out the battery.

It does not even reach a boot screen, nothing shows up on the screen, fan does not start. People on this forum has the same problem but they suggest to put the laptop in a oven and heat it (reflow). What could be the problem? Is there another solution other than a reflow? I dont feel like putting my motherboard in the oven.

A suggested fix for some Acer laptop power-up problems is to do the following:

  1. Remove the battery and external power
  2. Hold down the power switch for 30-40 seconds
  3. Plug in the external power cord
  4. Power up the laptop
  5. Reinsert the battery

You can remove or insert laptop batteries while it is on? Cool. – Synetech Feb 6 '12 at 0:44

It normally works if you change the CMOS battery in the motherboard

It is commom problem in Acer Travelmate 5200 series laptops
