[M1437G] Boot problem - Battery/AC adapter

[pddfactory]

Hi,
for some time now I had problem with turning it on (battery+AC adapter). I had to disconnect the AC to boot it. Unfortunately, few days ago even that trick didn't help me. I couldn't boot it using every combination of battery/AC. I have to mention that it doesn't work on AC adapter without the battery, but the AC is capable of charging the battery and powering the laptop when used with battery.

Do you have any ideas what may be the problem?

Are you able to start it up at all now?

I have had this problem before (same model) on my laptop, and my motherboard and some other materials were broken. Had to send it off for repair.
Funny thing is, when I got it back, after 2 weeks, it was broken again, this time the sata controller was dead.

I sent it to repair and they replaced the graphic card. It helped, but unfortunately I had to send it off for the third time. Maybe this time they will put good card in there.
