Check your keyboard connections. Also, when powering on the unit, try holding down any set of keys through the boot process.

If the keyboard is working and connected correctly, it will show a fault when booting.

Also, you can use a USB external keyboard to do your BIOS updates.

Might give this a try-right click on your Computer icon-click on Properties-then click on Device Manager. The keyboard is listed there. If it has a yellow exclamation point, or a yellow question mark, then there is a problem. Click on the arrow in front of Keyboards, then right click on the drop down named keyboard. There you can click on update drivers. That should solve the problem.

Reset BIOS? how to


With both PC and LAPTOP Motherboards,Pc Motherboards are easier to Wipe Passwords than laptops because of ease of getting to the Jumper on the motherboard normally by the battery on the motherboard.I would suggest looking online for the motherboard manual which should show you where the bios reset jumper is.Laptops are just the same but a lot harder sometimes to find this jumper. Hope this helps

My boot priority order changed now my computer wont go to my desktop


Hi!
Sorry, I hope I was not too late. You can fix priority order issue by restoring the default value of BIOS. You can do that by doing the steps below:
1. Reboot your Acer Aspire 5315 notebook.
2. Wait about 30 seconds until you see the Acer logo on your laptop screen.
3. Press the "F2" key on the keyboard to enter the Acer Aspire 5315 laptop BIOS menu.
4. Select the BIOS option "Load Default Setting" using the arrow keys on your keyboard. Then press "Enter."
5. Press the "F10" key to save the BIOS that is reset to the factory default settings.
Hope this helps.
