Quite an old laptop, but still I want to try to bring it back to life. The problem is I cannot even power it on, when I plug the power cable on a green light appears to show that is charging, but when I press the power button it suddenly shuts down. I'm studying electronics engineering (second year) so I asked my professor about it and said that it could be caused by a malfunctioning BIOS or the entire motherboard. If so, then it's screwed, but I just hope theres some way it could be saved. Any ideas?
