Laptop shuts off when unplugged, battery is fully charged

Laptop Presario 1200 shuts off when it is unplugged from the power source. The battery shows that it is charged and the fan doesn't come on. I try to restart it but it will only work when it is plugged into a power source. Help?

    Installed new battery, says it is fully charges yet when I unplug it from charger, it shuts down immediately. Power options doesn't let me choose when to switch from battery to elec. Not that I have found that is!

Chosenone, Even though the battery meter shows it fully charged I doubt it?s correct. Over time rechargeable batteries loose their ability to store power. How long depends on the battery manufacturer and how well you treat it but you can consider yourself fortunate if your battery lasts three or four years. Beware of people who suggest you take apart your batter to bypass the safeties or replace old battery cells. Defective or improperly handled batteries can overheat and cause fires when you least expect them. Let us know if you have any more questions and please don?t forget to rate this post.

Why does my tom tom keep going the shut down page every 10 seconds I have pressed reset but makes no difference I ride bmw r1200rt


One possible cause is that your battery is low or the battery can no longer hold a (good) charge. In this case, the TomTom is shutting down because there's not enough battery to keep it running, even though it is plugged into a power source.

To determine if the battery is the cause, try to charge the TomTom battery .... using a (USB) connection to your computer, or a direct power source (i.e. while the TomTom is not being used). Let it charge for a few hours until the batter charge indicator shows that it is fully charged (or just leave it charging overnight).
Then, unplug the TomTom from the "charger" and power it up. If the TomTom (battery) doesn't hold a (good) charge, the device will shut down within a few minutes, e.g. 10 mins or much less.
When you (then) plug the device into a power source, and it doesn't stay on (i.e. it keeps shutting down after 10 seconds), you can safely conclude that the battery is the cause of your problem.

Power schemes battery


Chances are that your battery doesn't / wouldn't hold a charge anymore. The laptop runs off battery power. When it is plugged in, the AC power "goes right through the battery", to support the laptop's operations. When the power cord is unplugged, and the battery doesn't hold a charge, the laptop will shut down, as your battery is (too) low to continue supporting the laptop's operations.

The easiest way around this problem is to get a new battery for the laptop.
If your battery is (quite) new (and a Lithium battery), you may wish to see if you can "revive" the battery's "life" ... first by depleting the battery (completely), then charging it (until it shows it is full, plus a couple more hours), and repeating this process a few times. If you're lucky, the battery will slowly/gradually start to hold some charge, but, don't expect it to be very long.
The (preferred) way to use re-chargeable batteries is to charge it fully, unplug it from the external power source, use it until it is depleted, then plug in the external power source to charge it up (fully) again .... and NOT to keep it on a power source all the time.

TURNS ON AND POWER TURNS OFF RIGHT AWAY.


Is the battery fully charged? If so unplug the device before turning it on. My roomates HP will shut off if plugged in while powered on it is most likely due to the compound on the heatsink.

Laptop won't turn on, battery won't charge


I had a similar issue with the Armada M700 from Compaq. Never did figure it out exactly. But I do know this. When you unplug the power chord and take out the battery and plug the power chord back in while the battery is out usually for some reason it turned on allowing me to replace the battery which would then begin charging. Your problem interests me because I can really relate!

Compaq Presario 1200 won't charge battery


dear N9YK

you can follow this

If you have a loose connection where you plug in the power on your laptop, or it works intermittently, you could have a bad dc jack. Symptoms
  • Move the power plug and the laptop loses connection
  • Broken or cracked dc jack
  • Laptop won't charge but worked on battery
  • Power LED and battery LED flicker when the adapter tip is moved
  • Battery won't charge
  • Sparks come out the back of the laptop
Why does this happen?
  • Flaw in manufacturer designs
  • Use of universal or non-original ac adapter
  • Lots of plugging and unplugging of the ac adapter
  • Tripping on or pulling the ac adapter cord
or you can check your dc amper in your adaptor

oke



thx
