2. Head to the bios again and look for a load defaults, save and exit. If the keyboard is failing you might have trouble there.
I know my first mistake was purchasing an Acer. Lesson learned! Now this morning I turned on the laptop, forgot about it and went out for a couple hours. When I got home it was in the BIOS set up. I had a hard time exiting. It wouldn't let me just exit. In case my kids touched anything I set the Bios back to previous setting and then it let me exit. Now it won't turn on. The battery is charged. The power light comes on, the disc drives does it's thing for a second and the fan kicks in, but that's all. The fan goes off and all is quiet with power light still on. This has happened before, but not for a long time and after trying to turn it on a couple of times it would. I've tried pulling the battery and power cord, holding the power button for a minute and even pressing the power button for a minute then replacing battery and power cord but still nothing. The model is an Acer Aspire 5734Z-4958. Any suggestions? Thanks.
