I've been working on this laptop, an old Dell Inspiron, that was brought to me because it won't turn on the first few times you press the power button. It will eventually come on (usually only when I press and hold the power button and let it cycle till it comes on) and once it's warmed up I can turn it off and when I power on again it comes right on. I have done a few things to narrow the possible issues. To eliminate a software issuse, I repair installed XP, ran MalwareBytes, AVG, ccleaner and cleanup; it still has the same issue. This seems to confirm my initial thought that it might be the mobo or the internal power supply. Any one else expierience this problem and if so were you able to confirm what was causing it? Any help is appreciated!
