|I took apart a friend's similar Acer laptop model recently - 5100-5328 - it's a little over 3 years old. It's keyboard doesn't work either. |
According to it's Owner's or User's manual, a USB keyboard should work without you needing to do anything, but NONE of the 3 USB ports work.
Take a look in the manual for your model - it probably says the same thing.
If it it does, if a USB keyboard won't work, the mboard on the laptop is damaged. You must replace the mboard if you want to keep using the computer.
You can't get rid of a laptop's Bios or System or Drivelock password by removing the cmos battery on moderm laptops (one less than about ten years old, or older) . The password is stored on a seperate chip that cannot have the password(s) removed by removing the power to it.
You can get rid of the Windows Login password by re-installing Windows from scratch, or by other means, but we have no may of confirming whether you should have the right to remove the password for Windows, or the Bios or System or Drivelock password for that matter.
People who have stolen a computer, or who have knowingly or unknowingly bought a stolen computer, or who are trying to access a computer that they shouldn't have the right to access, often claim they forgot a password, or that they bought it from someone who didn't know or forgot the password.
Do you have a LEGITIMATE reason you don't know the password(s) ?
