I've a Lenevo notebook N100 series & model No. 0689 3MA .
I was wondering if anyone can help me. My laptop will not turn on unless my AC power supply is plug in and turned on. Then my laptop will turn on. Without it I can't turn it on with just my battery.
I have checked that the battery is fully charged and works, as when I turn my laptop on and then take the AC power supply out it runs fine with the battery.
It just I can't turn on my laptop without the power supply. Its really ignoring.
This has happen before, but it normally just returns back to normal, or before I had to reinstall windows anyway, and once I had done that it was back to normal. But I try that this time and it hasn't work.
I really appricate it if anyone can help me.
