No battery is detected in dell 830


If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

Asus g1 laptop won't turn on & won't charge, what's the problem?


try to have your battery checked, maybe it is damaged or your cable maybe damaged. if your laptop wont turn on, your battery is discharged. and by that if you connect your cable and the battery wont charge either then, your cable may have a problem too.

Unfortunately, the charger socket in the motherboard does not drive electricity to the battery to get re-charge it. It is a typically motherboard problem(Do not confused with a power jack problem). I can not be repaired it.

Pasario 6500 laptop will not charge, charger is plugged in, turned on and laptop is running on mains power but it will not charge the battery


Most likely your battery stopped recharging. Depending on what type it is, and how old it is, it could be dead by now and needs replacing.
Most laptops can operate connected to their power supplies, even when the battery is taken out.
Some batteries need to be fully discharged for them to take a new charge and perform as new, up to a 1,000 times, according to their manufacturer's specs. Others have what's called a "memory effect". This prevents them from taking a full charge, especially when connected to the laptop almost 100% of the time, and using up some of their charge only ocassionally, when they are disconnected from their power supplies.
You can get replacement ones on eBay for less than the manufacturer's advertised price.
Good luck!

Itermttit ac and battery power on laptop compaq presario r3000. ac sees to work fine and then goes to battery (battery discharges in less than 30 miutes) - mp


your are probably experiencing a short in your ac cable, the next time it happens wiggle the cable, if the ac pops up in the task bar stop using the charger and buy a replacement.
PS check the slot where the adapter plugs in the back of the laptop to see if its loose, if it is take to the repair shop.
compaq are known for tis problem.

hmmm...sounds like either the battery is deep discharged, or the motherboard isn't passing the charge voltage through to the battery..
