http://ubuntuforums.org – Hi all, I own an Acer Extensa 5620-4801. Yesterday, the computer ran out of its battery and hibernated(while running Ubuntu). When i later plugged it to a power source and pressed the "Power" button, the laptop just won't turn on...Basically, while turning on the power button glowed green and then the Acer would start booting...However, this time, nothing happened when i pressed the power button...What could be wrong...I'm pretty sure its not some voltage problem as other laptops in our house are working fine... Thanks for any help (Hardware)
