Unfortunately, most manufacturers will not list the exact type and model of your CMOS (Motherboard) battery; therefore, you will need to open up your computer, locate the battery on your motherboard, and record the information about it such as voltage, chemistry, wiring, and packaging. If possible, remove the battery and take it to the location you plan on purchasing a new battery from.You may be able to find replacement batteries at a nearby electronic store like Radio Shack, or online via a Google search.

Seems the clock on my desktop compaq computer is running very slow. Where should look??


If your change your computer clock to fix it by double clicking the clock in the lower right of the screen. You turn the pc off and the clock is wrong or over time its wrong you may have a few things to look at

first check if the time zone (same way you look at the clock to change it buyt select time zone settings) to see if that is correct. If that is then the first thing is to purchase a new CMOS battery from a store liek walmart. These batteries are 1-4 $ depending where you get them and the quality. You can open the computer up and look for a silver battery about the size of a quarter. Remove it carefully while the pc is OFF. take it to a store and buy the new one then replace it.

Disconnect the power. Remove or reset the jumper near the cmos battery. Connect and turn on your computer for a minute. Turn it off. Reset the jumper to it's original setting and you're done. Put everything back together and you're good to go. Good luck!

Hello i have a compaq presario 5000 when i turn


This is a compicated problem. First when it boots enter setup by pressing the F10. Once you are in set up reset all settings to default. Save changes and exit CMOS. If that does not help the situation have someone make you a boot disk, reenter setup and put the floppy as the first boot drive and then CDrom. Insert the boot disk, follow the instructions to boot. Once you are up and running try to roll back the computer to the last recovery point that worked. If that does not work you may need to see a local repair tech.

Compaq presario sr1950 nx desktop - won't start


My suggestion would be to open the case and unplug everything and then plug it all back in again.
To test individual components, unplug everything but the CPU, memory, and video card to see if it starts.
Then one by one, plug the other stuff in and try starting again.

Trying to install intel 333mhz from same "era" ('98) that works fine in another computer. but in 4640, it hangs at "entering setup" screen


Check the machine to make sure if has a 333mhz operation level,,, and not like a 133 mhz. You can tell this on the model tag that shows the serial number and operation info.

Not keeping time


Go into the BIOS by pressing F2 when you first turn on the laptop. In the main screen you should be able to change the time and date. After you do that save the changes and exit and go into windows and see if the date and time is current.

Let me know how it goes.

Clock will not adjust properly


Inside the PC is a small lithium cell battery that may be going bad. Or, check for updates on microsoft update to get the clock settings where they need to be. Also check in your settings that you are set to the correct time zone.
