the dc jack (charging connector) can usually be bought for about 5 pounds or less from ebay. As far as fitting it goes it depends how confident you are. You will need to disassembel your laptop and remove the broken jack from the motherboard and then solder the new one on.
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
You normally need a compatible Power Supply plugged into the Laptop from the mains. Without this the battery will go flat.
If you do not have one a good place to look is Ebay, or the like simply put in the model name of your laptop and the words Power Supply.
EG: IBM ThinkPad T30 Power Supply.
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.
