Charging circuit laptop - Satellite Toshiba Computers & Internet

I would think the chances are that the new battery is ok. The power adapter should be fine since you operate your laptop from it... It is possible the charging circuit on the motherboard could be damaged.

It would be nice if charging were a simple operation, but a lot of electronics are involved inside the laptop to charge a lithium battery properly. I think the chances are the charging battery circuit in the laptop may be damaged is my guess. Take it in to a shop.

Power adapter board.

Unfortuneately that leaves the charging circuits on the motherboard that must be faulty, "this is so rare I have seen only one in all my years of service". But I think it is a good idea to have the charge circuits tested to be sure.

Clean battery terminals with a stiff toothbrush, plus the new battery. If no change! charge circuits need to be checked for output voltage, if okay! new battery is defective, If no! the charge circuits in the motherboard are the issue "very rare"

Either charger is not charging battery because battery is beyond its working life or Charging circuit on motherboard is faulty

If the AC power cord is the problem. you can just buy that from any computer store but if the problem is inside of the laptops charging circuit it the mainboard of the laptop needs to replaced. you can call HP for parts replacements.thanks

You probally have a dead motherboard port that charges the battery.

Because of BIOS. Basic Input/Output System.
Battery has 'lost track', of what the battery state of charge is.

Try Recalibrate BIOS

Hi,


If possible could you check output voltage of the charger with a multimeter? If you can get output voltage, then might be something wrong with laptop battery charging circuit. Contact Laptop Repairing Engineer.

What needs to be done is the jack that your adaptor plugs into has solder points underneath it. All the solder points need to be resoldered to make sure that there are no cracks in the solder that are preventing the jack from charging your battery.

After this is done if the laptop still isn't charging then if you know for sure your using the correct ac adaptor with your laptop then at that point the moterboard would have to be replaced.
