The laptop's battery might be weak to hold the laptop. The indicator will indicate the battery is ok, but when mains is removed there, it goes off. Try swtch on with only battery and see if it goes on and then off, it is the battery that is bad.

If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

Tip

UPS - Battery Fault


UNINTERRUPTABLE POWER SUPPLY
Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. Including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. If one battery is faulty in a set of batteries it will causes the whole battery system to fail and indicate a battery fault. A faulty charging circuit will not charge the batteries and will also cause a fault condition.

Lower powered and cheaper type UPS are switch over types, when the mains supply fails, the UPS switches over to the battery and inverter in milli-seconds which then supplies mains power to the computer and peripherals. A faulty inverter circuit and or flat batteries won’t deliver standby power when the mains supply fails.

NOTE the power waveform from these UPS is a pseudo sine wave (i.e. not a true sine wave).

The true UPS types are usually the higher KVA units (over 1500 VA) that supply continuous mains power. The mains power is connected to a charger which charges the batteries and the inverter draws power from these batteries and converts it to true sine wave mains power to the computer equipment, therefore there is no switch over time lag when the mains supply fails.

Laptop crashes and wont keep charged battery


Crashes when? What are you doing when it crashes? When it crashes does it boot right back up or do you have to wait a while then it will boot back up?

The laptop might be running hot or has a virus, but you'll need to answer the questions above to really isolate what is going on.

As for the battery not charging, either the Power Cord is bad or the battery is bad. If the power cord is good, it would normally charge the battery unless the battery is dead. Batteries only have a useful life and last for so long, then they have to be replaced.

Maybe your DC Power Jack where the Power Cord plugs into the laptop is bad. That would cause the laptop to crash (shut down) and it would also keep the battery from charging.

Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

Lenovo G550 battery shows fully charged but when you unplug the laptop, the laptop shuts down and will not start up again until power cord is plugged back in.


Shows a clear indication of the battery to be faulty. So in the first place remove the battery and checck the voltage, now keeping the battery off the laptop, plug the adaptor to the mains, Now checck the voltage in the battery terminals which is in the battery compartment. If voltage is present then the battery is bad as it is not charging.
However if there is no voltage then the main board has a fault in the charging section which must be looked into.

Laptop not turning on


If you replace the main battery and it will not charge, make sure the AC adapter is working (You can test the output with a multimeter) and make sure the LED on the Adapter stays on when connected to the system. Most likely, the motherboard has failed and will need replacement

I have a schumacher se-82-6,i dont use it much and have misplaced the instruction manual.how do i read the guage,when do i know battery is fully chargrd or battery wont charge? thanks erik


If you look at the meter, the charge meter of 100% is slightly above the 2 amp mark so it is confusing. because it says the charge represents the amont charged and the amp meter shows when there is no draw on the charger. so if the battery shows 2.5 amp on the amp meter, it's showing 100% charged. but yet they say it should go to zero on the amp meter, which would mean about 150% charged. i think everyone is scared of blowing up or damaging their batteries because the instructions manual is quite contradictory and confusing. well apparantly, they have several versions of this model to make it more confusing, but here's a pic of what i have.

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
