    Thanks, but there is no such visible compartment under this HP Pavilion xh485. I'd already taken off the RAM and NIC covers, and even removed the KYBD and HD...but cannot find a CMOS battery! If I ever find it I'll replace it: the machine is over 10 years of age.

Remove all components from your mb and bios battery. Place jumper to clear cmos and make short to battery cmos. Leave 1min and after place cpu and one ram in mb. Replace jumper from clear cmos in normal position and verify. If not display, change ram.

Black screen at startup


It sounds like the graphics card or on board graphics is causing the issue, as the external monitor is not working either. Hopefully its a graphics card which can be replaced easily, or there is an expansion slot for a graphics card to be added.
One thing you could try is resetting the CMOS by removing the battery from the motherboard and leaving for ten minutes. Replace the battery and try booting.

Toshiba satellite A210 11-P crashes when i disconnect the power lead


From Toshiba, try step-charging the battery or Battery conditioning procedures:

Batteries don't last forever. All types of batteries gradually lose their ability to hold an electrical charge as they age. Eventually, the computer's battery charge indicator may show that the battery contains less than a full charge, even though the battery has just been fully charged. The computer will then not run for as long a time from the battery as when the battery was brand new.
You may prefer to simply replace the battery if this happens, but you may also wish to try 'step-charging' the existing battery per the following instructions.
This procedure should work for the battery in any Toshiba notebook. Follow it only when you find that the computer will run from the battery for just a short while.
Check the User's Guide for more specific information about charging the battery in your computer .

Procedure

Step-charging the computer's battery

  1. Unplug the AC adapter from the computer, and turn ithe computer on. Let the computer run from battery power until the computer turns off, indicating that the battery is fully discharged. Time this interval, but not with a software clock running on the same computer.

  2. Remove the battery pack from the computer.

  3. Unplug the AC adapter from the computer.

  4. Wait at least 30 seconds. The first time through this procedure, use a soft cloth to wipe the battery pack's contacts and the AC adapter's plug.

  5. Re-insert the battery pack.

  6. Plug into the AC adapter into the computer again and check the fit of its plug in the wall outlet, making sure the connection is secure.

  7. With the computer turned off, let the battery charge until the battery status light or icon glows green, or otherwise indicates a full charge.

  8. Unplug the AC adapter from the computer.

  9. Remove the battery.

  10. Wait at least 30 seconds, then re-insert the battery.

  11. Plug the AC adapter back into the computer.

  12. Let the battery charge again until the battery status light turns green or otherwise indicates a full charge, again.
Repeat this procedure, starting from step 1, at least three times. Each time, check to see if the computer runs longer from its battery than the previous time.

Battery Conditioning:
IMPORTANT!!
Interruptions in the charging cycle can be responsible for an issue called "memory effect" which may reduce the battery's charging capacity. Whenever you suspect the battery performance is not at it's optimum you should try using the following "Battery Conditioning" procedure.

Before you start: Turn off your battery saving features temporarily.

***IMPORTANT*** Repeat the following steps 2-3 times!

  1. Unplug the power cord from the computer
  2. Turn the computer on and let it run until it shuts itself off.
    Note: Using the CD-ROM to play an Audio CD will speed the discharge.
  3. Plug in the power cord (While the system is off) charge the battery until the battery light changes from flashing green to solid green
  4. Remove the battery for 30 seconds and then replace it.
    Note: If the battery light isn't lit, wait a few moments, if it still does not light check your power connections.
  5. Continue charging the battery until the battery light turns solid green once again.
    **REPEAT THIS PROCEDURE 3 TIMES**

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
