Hp pavilion clock won't keep time

try finding the time zone you are in and use that to set the time, changing the numbers individual will end up with the time going back to the time zone time. So change the time based on the time zone

What video card can I use to replace the built in card on a hp a520n?

Here's a url where you can see the specs for your PC.

A compatible card would be AGP 8x but bear in mind, you've already got 64Mhz on board graphics built into *********** board.
Just search ebay using :- agp 8x graphics card, should give you a good idea of what you're after.

HI>> This problem started a few days ago. When I turn on the computer, it does not show the logging page, instead a screen comes up saying that REAL TIME CLOCK batteries are low or ONBOARD BATTERY...

Your PC should not crash from this issue. Your PC motherboard has a small (usually watch size) battery on it that provides power for the clock, and basic I/O settings, such as boot options, disk drives etc... The battery is pretty easy to replace, just open the case and you will see the battery held in a little socket. Make sure to turn PC off and properly ground yourself by using a static wrist band or leaning one arm over the power supply while taking the battery out. Take the battery and go to your local RadioShack, The Source, London Drugs etc.. and show them the battery. It should be a pretty common battery such as a CR2032 or CR2025 etc..
Once you replace the battery go into the BIOS by pressing F2, ESC, or DEL (which ever command shows on your screen for Bios Setup, System setup etc).. Change the clock to read the current time and exit, saving changes. You should not get this error for a long time as these batteries last much like a watch would.
If you don't change the battery, it won't crash your PC, but will eventually annoy you enough to replace it :)
Regards, Chris

The light on the back of the hp pavilion 520n is lit when it is plugged in, but the unit will not start up, nor do the fans run. Does this mean the power supply?

Possibly, you can subsitute a known good one and test it, however, there was an issue with some hP boards the "sunshine" mobo had a tendency to blow capacitors for example after some time. If the new PSU does not work it is likely that it may be a fault on the mobo.

Before replaing the PSU, check the mobo for bulging/ blown/ leaking capacitors (the small cylinder shaped components with a X on the top). If any are leaking or blowing ( bulging) the mobo is on its last legs

I have a quartz president wall clock, I changed the battery and set the time OK but the chime needs setting and I have no instructions as it is a very old clock

These are general quartz wall clock instructions as I dont know enough about what type/style of clock you have.
  • Open the access door to the dial and hands of the clock if required. Some battery-operated clock movements are sealed inside the clock case with a back panel that is screwed in place. To gain access to the hand set knob, remove the back panel screws using the appropriate tipped screwdriver.
  • Turn the minute hand (or turn the hand set knob at the rear of the movement if access is available) carefully counterclockwise or clockwise until the correct time is reached. Keep in mind that using the hand set from the rear would require turning the knob in a clockwise direction in order for the hands to turn counterclockwise.
  • Move the hour hand carefully with your fingers near the center of the hand to the hour that the clock is striking if the striking chime is not counting the correct hour. The hour hand is a friction fit hand and will move without engaging the minute hand.
  • Replace the back panel and tighten the screws with the screwdriver if removal of the back panel was necessary to access the hand set knob.
  • Close the front access door if required.
