Question about Acer Computers & Internet
I am trying to sort out daughters Acer Travelmate 311D, put cannot get pass Bios password, which is lost. I cannot find motherboard info. to find where Cmos Clear jumper is, any ideas please. Cheers, Malcolm.
If you can't find the jumper, just remove the CMOS battery wait for 1/2 + hour and the re-insert the battery. This will reset the BIOS back to the default settings and you then need to set the Time & Date.
It may not remove the BIOS password if the laptop stores the password on an EEPROM chip.

Tips for a great answer:
Almost all motherboards use a small coin sized CMOS battery to store
all BIOS settings along with the password. To reset the password, unplug
the PC, open the cabinet and remove the CMOS battery for approx. 15-30
minutes and then put it back. It'll reset all BIOS settings as well as
the password and you'll need to re-enter all settings.
If it fails, then try to remove the battery for at least one hour.
B. By Using the Motherboard Jumper:
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
