U hebt waarschijnlijk te updaten BIOS (Basic Input / Output System) met de nieuwste firmware beschikbaar op de website van de fabrikant. Ook in staat stellen TPM (Trusted Platform Module) in het BIOS handmatig.

LET OP: Het wijzigen van BIOS / Complementary Metal Oxide Semiconductor (CMOS)-instellingen verkeerd kan ernstige problemen veroorzaken die uw computer kunnen voorkomen kunnen opstarten. Microsoft kan niet garanderen dat problemen die voortkomen uit het configureren van het BIOS / CMOS-instellingen kunnen worden opgelost. Wijzigingen van de instellingen zijn op eigen risico.

I really don't know, my Brother is a computer repair guy and he came down and fixed it.

The term for this situation is called "bricking", it requires the bios chip to be replaced or a new motherboard.

You will need the BIOS password to enter the BIOS setup.
To do a hardware reset remove the CMOS batteries for 30 minutes. Once your BIOS password is removed, you will need to press the <F2> key during POST (Power On Self Test) to enter the Acer BIOS setup.
After you enter BIOS, go to the Boot tab and down to "Security" and make your changes there.
If you need help with the default password, please re-post your request.
Thanks and good luck.

try typing your password in with the caps-lock on. many times this may go unoticed if both password fiels show * instead of the actual password being entered. if that doesnt work for ya go here and chose one of the 5 options to recover or delete the need for a password. you must first download these and creat an .iso disk to be run at startup.

Good Luck and dont forget to rate my post! :D

If you have no video at all then turn off the laptop. Reseat the memory and then turn the laptop back on with just the AC Adaptor hooked up to see if you get video if not then try reseating the memory into the other slot and try turning it on again to see if you get video. If not then your motherboard may be bad. Just curious though after you turn on the laptop, does the hard drive light keep flickering like its trying to load windows?
