Re: I bought a used IBMA21 will not turn on

Try removing all memory, re-installing 1 memory in 1 slot, and booting. If that doesn't work, try the same memory in the other slot. If no, try putting pressure on the memory (as if to push the slot into the motherboard). The battery really doesn't matter, and I would take the battery out, only using the ac adapter.
Good luck

Wont turn on

On all Panasonic Toughbook Models,
if the unit will not turn on try the following:
Step 1: Unplug the unit.
Step 2: Take OUT the Battery Pack.
Step 3: Plug-in the unit.
Step 4: Turn On the unit.

The battery pack acts like a giant capacitor and can
prevent the unit to turn on, especially when the unit
was previously used on battery pack and was allowed
to fully discharge to below 5%.

When the unit is turned on WITHOUT a battery pack,
then a single Green light should show on the front
edge of the unit when the cover is open facing you.

When the unit is plugged in WITH a battery pack,
then you should see a yellow, orange or green light
which shows the battery is charging. When the unit is
turned back on, then you should see two (2) lights,
one green and the other yellow, orange or green.

If the unit is plugged back in and either with the battery
in or out you see no lights whatsoever, then chances are
that something is wrong with your AC Adapter/Power Supply.

Good Luck!

My battery indicator won't turn green when it is fully charged.what is this issue?

It is possible one of the battery cells has degraded enough the battery is not showing a full charge, or there is an issue with the green light, but this is minor provided everything is working.

Battery light won't change colors, drops to 0% once unplugged

Let the battery completely discharge all they way and let it sit for a day or so. Some times when a battery is new most user do not let it fully charge and then completely drain this causes problems for long use batteries. Then give it a try. It also sounds like your plug your cord that connects to the battery may be faulty. Did you by a different cord with the battery? Or use the one from your old one? If you did. This is a "No No" always buy the cord that come for those battery since they are rated for the particular battery.

Dell 9400 wont show AC power icon

If the computer is connected to an electrical outlet, the about10.jpg light operates as follows:
  • Solid green: The battery is charging.

  • Flashing green: The battery is almost fully charged.

If the computer is running on a battery, the about41.jpg light operates as follows:
  • Off: The battery is adequately charged (or the computer is turned off).

  • Flashing orange: The battery charge is low.

  • Solid orange: The battery charge is critically low.
Looks like the AC adaptor is faulty.

Getting hot underneth

Both batteries could be dead. But if you bought a new battery, it's unlikely. I don't know what green light you see, but if it's on the power adapter, it just means it's turned on--not that it is charging.
Two possibilities: Your power adapter is bad or the motherboard is bad. Because you say the computer works if plugged in, then you have ruled out the adapter.
You should be checking/cleaning the battery contacts and if all else fails, going for a new motherboard.

That usually indicates battery is beginning to go bad. Eventually it will not hold a charge and will need to be replaced.

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 .


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:
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.

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