How to change dates on my personel computor


Click on the Date at your taskbar. When the analog clock shows up, click change date and time settings. A popup windows will appear.

Then, click change date and time, and seti it as your preferred. Click ok and it's all done.

But if you restart the laptop or pc and you date reverse back to previous one, then you need to change the CMOS Battery inside.

Generally, the battery is the flat one used in the watch but the size might be different for some model.

Which operating system ?
The Compaq Presario CMOS password is an administrative security measure built into the firmware of a Compaq computer.

This password is stored in the motherboard's BIOS (Basic Input Output System) and provides for hardware-level security.

This password may be accidentally set or forgotten over time and must be reset in order to boot the computing system.

Disconnect the Compaq computer from any electrical sources and remove the side access panel from its case.

This may require the removal of one or more thumbscrews on the rear of the computer case.


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules

Locate the CMOS battery.

This battery is a round button-type battery located in the bottom-right corner of the Compaq Presario motherboard.

Grip the battery by its edges and pull it straight away from the motherboard to remove it.


Press and hold the power button on the case for ten seconds to remove any remaining electrical current from the computer.

This removes the CMOS settings and returns it to the default state of having no password set.

Replace the CMOS battery.


Replace the computer's side access panel and re-establish any previously severed electrical connections.

Got message "CMOS battery low" What steps are


Assuming you know how to get into your computer and identify the CMOS battery, you just need a pair of tweezers or similar to remove the battery. Once it has removed, take it into a drug store or pharmacy and find the exact same battery, and replace it in the motherboard. If you can't identify the CMOS battery, please let me know and I can help you with that.

Aloha, replaced cmos battery (assumed dead) because emachine hangs on E logo screen and neither option to press F2 (bios settings) or F10 (boot menu) do anything. Tried putting in Recovery media back up...


First of all you should always follow anti-static procedures before doing anything inside a PC. Unplug the power, earth yourself on a door handle, radiator or some metal or even touch the chasis of the PC to earth yourself, then you can start.
Remove the cmos battery again and some where near the battery is the cmos reset jumper, you need to move this jumper to reset cmos and leave it for 10 seconds. Move the jumper back to the previous position and reinsert the battery and all should be well.
Good luck

I THINK YOUR MOTHERBOARD BATTERY MAY BE DAMAGED OR DOWN. YOU HAVE TO REPALCE THE BATTERY AND TRY AGAIN TO START THE PC.
