Acer Aspire 4520G laptop 10 months old, newly re-installed system 1 week ago. PROBLEM: 2 keys and the enter key suddenly doesnt work, so now I cant enter my bios password. I have tried to press numlock and fn and all other keys, but I just get a beep. I cant locate the battery on the motherboard to reset bios. The problem occured while using the laptop so I restarted, and now I cant get beyond the password screen, which is the first thing that appears after starting. It doesnt help pressing any of the F-keys, the password screen is the only screen that appears, so I cant boot from external disc or other. Plz help

Re: Keys doesnt work
Ok..... firstly check to make sure the "NUM LOCK" is off!!! if no joy

This may be a battery power monitor issue. Try disabling the "Mircosoft ACPI- Compliant Control Method Battery" device. This is located in Control Panel-->System-->Hardware Tab-->Device Manager-->Batteries. Had similar problem with 2 Acer Aspire series laptops (diff models). 2 and 3 year old. Original batteries (both still hold charges for 1.5 hrs of normal usage). Running WinXP, one with SP2 and other had SP3. Both came in the last month with slow jerky TPAD function and nearly non responsive keyboard access. Checked the usual; virus, spyware, hijacking, driver conflict etc. Cloned drive and factory installed..still same problem with kb & mouse. However an external USB keyboard and mouse functioned normally (no lag). Noticed with Battery removed kb & mouse was normal. Finally found disabling ACPI control battery device resolved this issue while allowing laptop to run on either battery or AC.
