Battery not charging, keyboard malfunction & screeching fan sound

The battery or the charger may be malfunctioning. Please verify that the computer recognizes that the power cord is plugged into the computer. There should be a plug icon over the battery in your lower right hand corner. If it doesn't show the plug icon, and the battery is draining your charger is likely bad. Otherwise your battery is more than likely going. If your model is several years old, I'm afraid to say that after constant (or even semi-constant) use the battery will die after 2-3 years and need to either be replaced or used less frequently.

Hello,

Contact Acer and they will replace it free providing you can produce a proof of purchase less than one year old. Those netbooks have one year parts and labour warranty on them and Acer is very good about replacements like this.It shouldn't be a problem.

Hope this helps!

Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time.If the battery drops to an unacceptable chargelevel then the battery needs to be replaced.

YOU MAY HAVE A BAD MOTHER BOARD

The only solution is a new battery.

How long have you owned the notebook? This sounds hardware related. If so then the touch pad would have to be replaced.
Thanks,

This sounds very much like a dead motherboard. I would suggest you get a professional to look at this or send it to acer. Visit thier site if you wish to. I would offer more help however laptop parts are expensive and tedious to replace.

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.

Just resolved same problem on Acer Aspire 5000 by removing the battery, then goto device manager and disable "Microsoft ACPI-Compliant Control Method Battery" you can then put your existing battery back into the latop with any problems with the keyboard and touchpad. Mad solution I know but it worked for me

are you sure the battery is good? How old is the system and battery? Do you have any way to check voltage at the battery terminals?
