Dear Bob,

When this happens, in general it is because the computer's real time clock battery (also known as RTC battery, CMOS battery or BIOS battery) is depleted. It is not the power battery at the back of your device - generally it is located inside the PC and looks like a small coin with the size of a dime or a quarter. If you search in for CR2032 or CR2016 you will see different brands and assemblies for them.

It is the power of this battery that is used to maintain the real time clock circuit working when you switch off or remove the power or the main battery from your PC, keeping the date and time being updated continuously.

To change it, you will need to unscrew and remove the back covers of your device and look for this kind of battery. Buy another one with the same size and thickness (check their model, like the ones mentioned above) and reinsert it to the same holder where you took it from. If it is soldered to a cable and connector, you will need to find one assembled like that or you will have to ask a repair technician to do unsolder the cable from the oldest one and solder it to the new one for you (always remembering to isolate it with electrical tape before connecting it to the circuit, to avoid short circuits).

In the next time you power your device on, it may warn you that the CMOS battery was changed and you will have to enter the BIOS setup and adjust it accordingly. The next time you switch it off and on again, it is supposed to work properly, without resetting the date and time.

Hope you may find this helpful!

Best regards,

Miguel Luiz Martins

How to set date and time on asus tablet for camera

If it is an Android tablet you should have correct time once you connect to the internet automatically. If it is wrong go into settings and it should be under "Date and Time" . There are various options like 24 or 12 hr format. By default the box for "Automatic Date and Time" which uses network provided internet should be checked and just connect to wi-fi somewhere and you will be all set.
If is is a Windows based OS click the bottom left corner where time and date is and you will see the option to change it.

NUM Lock

I solved this on a toughbook. The numlock was activating while windows started even with the regkey set to have it off.

All I had to do was restarting the PC waiting for windows to activate the numlock again during the shutdown process and then hitting the numlock once before windows was done.

Next time the Toughbook started the Numlock kept off!
