1.	Solve : Laptop keeps restarting?
Answer» I have an acer aspire 5741g that doesn't switch on . When I try to switch it on then the light that shows that it is on stays on for about 5 seconds and then it goes off and repeats this process . The screen doesn't come on. I thought that it may be the battery as the one I had was only charging to 23% however it still restarts. I have unplugged everything except the power. Help anyone ?First make sure the charger output voltage is what is specified on the charger itself. Use a volt meter to test it. It sounds like the motherboard INSIDE is getting power, but there is obviously a hardware issue going on somewhere. The problem sounds very similar to some of the HP DVxxxx models that have the bunk cooling system causing the solder that bonds the north bridge/GPU to the motherboard to crack causing disruption of current/data flow, which requires reflowing the solder which bonds the chip/s to the motherboard... I've repaired a few of these myself. On the other hand, the solution could be SIMPLER than that, but you may have to disassemble the laptop. But start with some SIMPLE stuff like reseating the ram, hard drive...etc.. Try starting up with only one ram MODULE installed at a time, then try one ram module in each slot to rule out a possible funky slot... If you have no joy at that point your going to have to disassemble the laptop and do what some call a "bare bones" boot of the system, leaving everything disconnected except those things which are absolutely necessary for the laptop to boot, to isolate the problem. If you're not use to this kind of repair you'll have to bring it into a local tech and may be more expensive to fix than it's worth.

If this doesn't work, you may want to try taking it to a service man.
