Tip & How-To about Computers & Internet

Laptop is plugged in but says it is running on battery.

You have your laptop plugged in but when you check it says that you are running on battery. Or, you have your laptop plugged in and it will not work because the battery is dead.

Both scenarios depict a broken power port on the laptop or possibly a bad power supply. Checking the power supply is easy. Using a DMM on volts DC set to 20 place the red lead on the center pin and the black lead on the outside of the plug assembly. If you do not have the correct voltage as listed on the power supply then you need a new one. While holding the leads on the power plug wiggle the wiring to make sure there are no breaks. If the power drops to zero at any time you need a new power supply. A good site is http://www.impactcomputers.com .

Many times people do not realize that their power port is broken until it is too late. If you continue to use your laptop after the port is broken you will destroy the power supply portion of the mainboard and it will cost you half as much as the laptop cost to repair and may make it not worth fixing.

When you realize that your laptop is not running on AC power, and it could be intermittant, you need to immediately take it to a repair facility to get the jack replaced. The average cost should not exceed $150 US.

This is not a repair procedure that I can walk you through. You can only get your unit repaired at an experienced reapair facility.

dell inspiron said battery low plug into charger, when plugged in charger light goes out and laptop will not power on, why?


Remove the main battery from the laptop and try power, if it works the battery is bad, if no change the charger needs to be checked for proper voltage. Since your laptop is less than a year old you should have warranty for up to the year, check this asp and find your paperwork should verify.

wall plug not working


Hi Gabriel,

Try another wall plug first. If still no good, remove the battery from your laptop and try plugging in with no battery. If still no good, test your laptop power supply with a multimeter to see if it is putting out the proper voltage. If you can't do that, buy a replacement power supply. Many stores sell universal power supplies that come with tips to fit most laptops. If it still doesn't work, take the laptop to a service shop and have it checked out.

Hope this helps!

My laptop won't turn on even though it's plugged into the recharg


Try removing the battery and running the laptop just on the p/s. If it works like this the battery is dead. Otherwise the laptop has a problem.

If the battery is dead, buy a new battery or run it on p/s alone.

Laptops should be run on battery alone as much as possible, or the battery dies.

toshiba satellite m35 power issues


Hi !
While power off, disconnect the power adaptor.
Take off battery.

Plug the power adaptor back and try to start !
Is it running?

If yes, than the power adaptor is OK.

Now shut down and disconnect the power adaptor.
Put back your battery and start!
Leave it untill you 'empty' the battery.
Do not start your laptop.

Plug the power adaptor and do not start your laptop yet.
Is there a led idicator showing that the battery is charging ?
Does it shows when the battery is full charged (e.g. red/yellow=charging, to green/off charged)?
If not, leave it for at least 3 hours. After that, start your laptop (adaptor is plugged) and see if you still have an icon saying charging 99%.

If that is the case, then something is wrong with the battery.

Check your warranty, and replace it.
DO NOT OPEN the battery - nothing interesting you will find inside - nothing you can do !

Regards.
