Cannot turn on my computer! Hi! Cannot turn on this laptop. If I plug it in with battery in - status LEDs are indicated as: Power/Suspend LED - lights up red; Battery Charge/Discharge LED - bliks red; If I plug it in with battery out - status LEDs are off; When I try to turn computer on in both cases Power/Suspend LED turns on green for a half second as soon as I release the power button and I can hear as ventilator span on, but after half second it all turns down and returns to previous positions.
After looking into this a little bit, here’s the first thing I would try. Remove the battery from the laptop, and unplug the AC power cable from the laptop. Hold down the power button on the laptop for 1 minute, and then let go. Reinstall the battery, and plug the laptop into AC power. Try to start laptop now.
Take your computer to a store, let the professionals to do the trick.
