Charger seems to have both red and green lites flashing at the same time no sequence and both batteries connected read 4.0 VDC, are these chargers repariable or throw aways


Your manual is here. The section on charging states, that green blinking means your battery is fully charged but blinking red means that your charger is faulty. I would say repairable.

1. Plug the female connector of the AC power cord (supplied) to the AC receptacle on the charger and plug in the male connector on the AC power cord into the wall outlet.

2. The On/Off LED indicator is blinking RED, this is abnormal. Unplug AC power cord from the on-board battery charger and wall outlet. Charger may need to be replaced. Contact an Invacare dealer or qualified technician.

3. When the On/Off LED indicator light is Off, charger is Off.

4. When the Charge LED indicator light is YELLOW, the batteries are charging.

5. When the Charge LED indicator light is solid GREEN, the batteries are fully charged (as their condition will allow).

6. When charging is complete, unplug the male connector of the AC power cord from the wall outlet and then unplug the female connector of the AC power cord from the AC receptacle on the charger.

Why is my laptop unable to run off battery power, even though battery shows fully charged and AC is unplugged


It's time for you to replace your battery.

how old is your laptop? and how do u use it - do u leave it plugged into the wall socket all the time? It's common for batteries to die out after a couple of years. however, if the computer overheats or if you leave it plugged in all the time, it's life cycle will decrease. Charge - discharge cycles. That's how you are suposed to do it.

Computer working perfectly fine one day, the next computer won't turn on for no apparent reason. when switching the power button on, computer begins to boot up for a brief moment, then automatically...


It's probably your logic board. One thing you can try that may help you out is to take out the battery (if you can) and press and hold the power button for 10 seconds. If it's a capacitor problem on the board that should discharge it. If that doesn't work then you should probably try to turn on the computer while holding CMD + Option + P + R to reset the PRAM. If that doesn't work then you're probably going to have to seek professional help.

hello

shut down computer - unplug power cord from laptop - remove the battery from laptop - plug Ac adapter into computer and Ac outlet (wall)
turn on computer
if computer does not turn on, replace the AC adapter and cord - then place battery back into computer
plug in new Ac adapter and cord - recharge battery - if orange light stays on after 4-6 hours of charging battery, you need new battery as well - replace battery, charge it up and it should be fine

if you have attempted these steps before and no change occurs, then you may have issue with power connection in computer - locate a service centre to replace power connection on computer

Toughbook will not start, we have it plugged into the wall and when we switch it on the battery light turns red and nothing else happens? Thanks, Brad M.


> battery light turns RED

For Panasonic computers, that indicates that the battery is almost completely discharged (it's YELLOW while charging, and GREEN while fully-charged).

So, my guess is that your AC adapter has failed,
and that your battery needs recharging.

Or, the socket where the AC adapter connects into your computer is damaged, such that no power from the AC adapter is reaching the computer.

Take a "MultiMeter" and check the voltage & amperage output-level from your AC charger. If "zero", go onto eBay and search on the part-number, to find a compatible replacement part.

Charging


USB Cable Make sure that the USB cable is properly plugged in and use the original cable that came with your player. Try a USB plug o the back of the computer. These plugs have more power available.
Computer in Hibernation mode Make sure the computer isn't entering hibernation or sleep mode while the device is connected. The computer must be ON in order to charge your player. Check you screensaver and power settings.
USB Port 2.0 Make sure the player is connected to a USB 2.0 port (1.1 occasionally causes charging problems).
Battery Make sure the battery is fully charged. It takes approximately 3 hours to fully charge the battery.
Latest firmware Depending on what Sansa player you have, make sure it's up to date with the latest firmware.
AC charger (optional) AC chargers (sold separately) have a 500-1000 milliamp max output, which provides much better charging ability than a USB port. These accessories are available on our online store.
Next try and reset the player. Resetting the player: 1. Slide and hold the Power switch up for approximately 20 seconds. 2. Release the Power switch. 3. To turn the player on, slide the Power switch up then release instantly.
Once it is back working, go to the SanDisk support site and get the updater program and update your firmware.

I have a new e627 used only once before today. Battery connection was partially out and screen indicated low battery. After five minutes screen went black and now I cannot power up.


Maybe your battery is totally drained.

Try to connect the AC adaptor of your laptop and plug it to the wall outlet and let it charge for 3 hours or more. When you plug it on the wall socket, it won't show the laptop's led blinking since it was totally drained. But after 3 minutes or more, it will start to show the blinking led to indicate charging. When blinking stops led light disappears, it is fully charged and ready to use.

Remember: Do not use your laptop while it is plugged in to save your battery life. When at home, remove the battery while it is fully charged and plug the AC adaptor directly to the wall outlet. It will still work without the battery as long as it is plugged directly to the wall socket.

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.

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
