Asus G51J supply problem (i think)

Hi there.

I've got a problem with my laptop and I really dont understand what is the cause. The problem is that I cannot turn on computer without battery on.

If I only get the power cable connected to the pc without the battery on the pc doesnt starts but after it starts I can remove battery and PC still working. Another thing that happens is if I have pc running with battery and cable I have the information that pc is not connected but the battery duration is always 10 hours

I have no idea what the hell is happening here.

cheers
(soz for my english)

 

That actually sounds like it might be a short in the motherboard or the AC adapter itself. The battery might be completing the circuit which is why it would power up only with the battery in the machine. Either way, it sounds like you are going to want to contact the manufacturer (or your reseller) to have it looked at.

 

Have you tried removing the battery and ac adapter for a minute?

Try resetting your BIOS to user defaults too.

If neither of those does it, it could be a problem with your motherboard or the AC adapter. If you are still under warranty consider sending it in for repairs. See: http://forum.notebookreview.com/asus/487940-asus-rma-warranty-guide.html
