Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

My dell laptop isn't charging when plugged in. What should i do?


Dell chargers have a centre pin to allow the laptop to sense that the charger is a genuine Dell one. If the battery is not charging then:

a) Battery is faulty (old and dead)
b) Pin missing on the charger, wire broken or not original Dell device
c) Charging port on the laptop has become loose.

Hope this helps.

Cooling fan stopped working


any 18-20 volt laptop charger should work only need correct power plug and that can be easily changed if necessary with soldering iron and volt meter. using old charger plug as replacement. volt meter is used to check out correct polarity of plug before and after you re solder plug on.generally outside is -ve and center is +ve ,alternatively go to ebay or google and type in Sony Vaio PCG 7Q1M charger,or type in part number ,or try 18-20v laptop charger, that is what I do when I need a replacement charger,cost around $10 delivered usually.

My laptop is working only via battery


That means your Ac charger is bad so you have to look for another charger of thesame specification voltages and use

SAMSUNG LAPTOP PLUGGED IN NOT CHARGING


try removing the battery and just use the mains power. If the laptop works you may need a new battery. If it doesn't your charger is faulty.

When i plug the charger in the first time it is working but when the charger is unplug the laptop is not working.


Hi Tim, As per my understanding you are experiencing issues with the laptop not working without a charger being plugged in.In this regards what I would suggest you do is see if the battery charges with the charger plugged in and in case the battery does get charged see if you are able to power on the laptop with just the battery connected and no charger plugged in.If you are able to get the laptop to turn on only with the charger connected and unable to power on with just the battery then it would be an issue with the battery not getting charge.So before you replace the battery please unplug all external devices from the laptop including the charger and the battery and without the charger or battery connected to the laptop please press and hold down the power button for 30 seconds after which please insert the battery into the laptop and see if you are able to turn on the laptop.This step is performed so that we could drain out unwanted static electric charges from the laptop.In case this step does not work please do consider replacing the battery since it would be an issue with the battery not getting charged. Best wishes for your effort.

Laptop stopped working and now not starting up. I think the battrey is dead and charger not working. it is HP laptop


If the charger has a light on it when it's plugged in and it's not on when you plug it in, then yes your charger is bad. if the light is green then you have issues with the laptop. If no light, check the voltage with a volt meter to see if the charger has power. good luck.
