How To Remove Keyboard To See Mother Board
I have a acre aspire 5742-7653 and the power supply rerely powers the unit without jiggling the power connection at the computer case. I want to remove the keyboard or other items to see the mother board. I think the power supply at the mother board may be broken or the solder loose. I removed all the screws from the coase bottom but some still hold the keyboard on. I can not find the last screws
