It's on but not charge

It is possible the charging plug socket on the computer is defective.

Hello. There is a hardware failure with the laptop not the AC charger. AC chargers have some range of protections of their own. If the power requirements of the laptop are bigger then what the charger can handle, the charger will turn off. Also other parameters can bring the charger offline. In your case, you have a problem with a small chip, the battery charge controller unit, which regulates the amount of current required to propperly charge the battery. When this thing fails, the charging requirements for the battery are reported rong and the AC charger is forced to give more power then necesary. This results in disconnection of the AC charger ( an internal fail safe of the
AC charger) and the laptop to swich back to battery power. When the laptop is turned off, it can charge the battery because the power requirements are low, having all processor, main board, hard disk etc turned off. Therefore the AC charger can handle the load. However you will need to have it checked by a service center as it is a hardware fault. Both AC charger and laptop needs that check.
The charge controll circuit needs to be replaced probably. It will be a somewhat expensive repair. Don't buy any other battery untill you have the laptop checked.

Yes you should when the battery is low.
You can check the amount of charge in your battery by -
Open Control Panel - Power Options - click on Power meter tab - un-tick Show power levels on each battery.

there is a possibility the battery has shorted out, try removing the battery and powering it on by a/c power if that works get a new battery, if not get a new charger

good luck

Hi,
First of all you have to determine whether it's the battery, charger or the laptop itself.
Remove the battery and boot the laptop on AC power only, if the laptop boots up you can rule out the charger and the laptop, you may need a new battery if that is the case.



Regards.

Sounds like you have a faulty ac adapter or jack on the laptop and its not charging the battery fully. More like a trickle charge. I would recommend leaving the laptop on default power settings or the best power settings and see if their is a differance in life or either shutdown the laptop and let it charge until the light shows fully charged.

Check if there is a green light on the Adapter, on the black Box, if it is not there, please get a new adapter

Change your AC charger.
It's NOT charging "When the laptop is plugged into the AC, the power meter in windows tells me that the power source is still batteries, and the battery level drops by about 1% every few hours"
That's the reason why: "battery has completely died"
If you do not change it you'll continue to "still it gives me the same low battery indication and will not turn on. "

well...this one is interesting, for certain. You bought a display model, so the chances of it working off battery are mighty slim. Could be that the m/b was running off ac power all the time, and can NOT charge a battery. I'd take it back, and have them show you that it will run on battery, which is considered a fairly important issue with laptops, at least around these parts on Hawaii
