Sometimes when I press the power button, the laptop screen won't turn on. After trying on/off a few times with power button, I give it a few hard punches on its back, and then it eventually turns on! Once it turns on, it goes fine.
I think there's some problem with power on/off button that is little hard to press to turn the computer on. Could it be something wrong with the power button, stopping the laptop to boot up?
I have also tried taking out the batteries, leaving the laptop unused for sometime and then trying to boot up, but this never worked for me.
Also, the sounds or keyboard doesn't work at all unless the display is turned on first.
