LOL, Nope, there is no problem with the battery. That's the way it's supposed to work.
When you run on the battery the laptop reduces or stops certain things
to conserve battery power. Haven't you ever noticed that once you remove
the power cord the screen goes dimmer. The laptop is conserving energy
and that will cause it to perform at a slower pace or speed.
Unplugged laptops generally go into power saving mode. They will slow
the CPU speed, stop the hard drive more often and lower the brightness
of the screen (big power savings) all that good effort is lost when you
remember that the power supply you use to charge the battery is making
more heat . When you reattach it to the power adapter it goes back to
Full Power Mode, and recharges the battery as well.
Here's a rule of thumb that I always follow. If i'm near an electrical
outlet, I use the power cord. I never use my battery unless there is no
electrical outlet near by. This way my battery is always charged for
times that I really need to use it.
Measure the voltage at the terminals of the battery in the laptop. If there is no supply then the power section in the lap tops main board is faulty and needs a check.
However if there is voltage then the battery must be checked if this has failed to charge and is defective. check if the cord from the adapter is not short as it will result in DC power cut off.
try removing the battery and just use plug power only if it boots normally then change the battery and the change the power supply unit as well I would just start with the power supply unit first then see if the battery charges up if not the battery is bad replace it. Now if the computer will not start with the battery removed then you have a power supply issue.
Change and replace it. Hope this helps. Also when computer lap top get hot they will shut down to protect the computer wait and let it cool down then try to restart your computer. If this does work and the lap top restarts normally get a fan cooler that is USB powered and the lap top sits on top of it. Also make sure the fan is running and is not stopped. Clean and dust it out once in awhile. I hope this assists you with your problem. John
If you were given a laptop with a brand new battery, it does need to charge for a while and depends on the manufacturers suggested charge time.
You should be able to power the laptop on without the battery attached. If you can't, you probably have a power supply issue on your hands or a bad component on the mother board. It may be less expensive to just get a new laptop.
press the fn key on laptop hold it down and then press the power key on the laptop. once u see any display on the screen you will get some tests running on the screen. The system will show you the error message which u need to note down. else you can do a Flea Power on your laptop. Remove the adapter and the battery and then press the power button and hold it down for 30 seconds then connect the battery and adapter back and try to turn on the laptop. See if the magic works for you
Hi there. You must only use power supplies which are specific to that particular laptop, even if you have a power supply of the same voltage but the amps are different it may power the machine but in my experience they have blown the PB (power board) which has resulted in no charge at all right down to the motherboard itself being blown. I suggest you use the power supply specific to that laptop.
Hi there This is a common problem with laptops, you will need to have the battery checked as it could be damaged and needs replacing. Alternatively it could be the motherboard or the power supply itself which is faulty
the best thing to do is to get the help of a qualified technician(better go to a toshiba service centre) they will help you with this. try removing the battery after turning off the computer and removing the power supply.reinsert the battery and turn on th notebook. it should work fine. else contact the technician.
