You need to change the internal clock battery. It's referred as a CMOS battery or a system battery. It will most likely be a silver button cell...either a 2016 or 2032. You will most likely find it by removing the main battery and one of the bottom access covers. After you change it, boot up to Windows and change the time and date. It should now retain the settings.
All laptops have a CMOS, or "Complementary Metal Oxide
The main purpose for the CMOS battery is to keep the system
time, date and BIOS settings even if the computer is turned off or the main
Individual Acer Aspire laptop models differ somewhat, but
the general steps are the same when replacing a dead CMOS battery.Preparation
Read through the owner's manual for your particular Acer
Aspire laptop to determine what kind of CMOS battery you need.
Purchase the battery through Acer or a local or online
computer parts dealer.
Turn the laptop off and unplug it.
Also unplug any external hard drives, cameras or other
Turn the laptop over (bottom facing up), then touch
something metal to remove static charge. Removal
Remove the Phillips screws that secure the motherboard cover
(refer to your owner's manual if necessary), then release the cover from the
clips on the bottom of the plastic casing.
Lay the cover aside, then locate the CMOS battery cable on
the right side of the motherboard. Unplug the cable, then remove the battery. Installation
Plug the new CMOS battery cable into the motherboard.
Slide the battery partially under the laptop casing to hold
it in place, then align the cover with the slots on the bottom of the laptop
Replace the screws, then turn the laptop back over. Settings

"F2," F10" or the "Delete" key) before the operating
Follow the BIOS prompts or refer to your Acer Aspire owner's

Any time the CMOS battery is unplugged for more than a few
seconds, your BIOS will be reset to the default manufacturer settings.
If you make any changes to the BIOS that cause problems with
your Acer Aspire, unplug the CMOS battery for 3-5 seconds to correct the
You need to set the correct date and time in your system BIOS. To access that you need to press the correct key when the computer is first booted (usually DEL or F10/F2/F11).
Most computers will have a message stating press xx Key to enter setup or etc.
If this problem persists even after setting the correct time in your BIOS, your laptop needs a new CMOS battery. I recommend having a professional do this.
go to your control panel (from teh start menu, or round blue icon in the bottom left corner) and look for power options. you can customize power settings in there, most laptops are set to go into suspend mode after sitting for a while to save power. you can set the amount of time that it waits before suspending itself, when its plugged in you can set it to stay on all the time. there are seperate settings for when it is on battery as well.
The BIOS battery keeps the Date and Time correct, if the battery is flat the date and time will be wrong or you will get an error date and time error. You need to replace the battery with a new one. Your friendly computer shop can help you if you don't know how to change the battery.
Thats a fairly easy problem. The problem is that your laptop is not recieving enough voltage to keep your battery charged. Your adapter is more than likely the culprit and needs to be replaced not the battery. You can also start by going to click on start, then control panel, performance and maintenance, then power options, and then configure and make sure your power options are set correctly. Thats should fix you up!
