My laptop stopped charging and i lost battery and now it wont charge at all, even tried a universal charger as well.

IF you are not using a Dell charger that is the first thing to try. They are proprietary and wont run the laptop in some cases involving the battery. There could also be an issue with the MOSFET power transistors that may have happened at the same time. This is not easy to check or repair.

When you say it won't charge, does it charge at all?
1. It indicates that it is charging, but as soon as you unplug the charger the battery quickly or immediately indicates it is dead. If the laptop is off, the LED on the laptop shows it is charging but the battery is always dead,

Or: 2. It is as if you didn't have the charger plugged in. No light on the laptop at all when the charger is plugged in.

Possible solutions:
1. The battery has died and is no longer capable of taking a charge. An alternate explanation if you can't even get the laptop to turn on even though the laptop charge LED is on, is that the internal power supply that converts the incoming and battery voltage to all the voltages required has died.
Or: 2. The power connector inside the laptop is a common failure point. The solder joints break from various minor shocks over time. This is going to become more common with lead-free solder as it is more brittle. Less likely is that the charging circuit inside the laptop has failed.

LOL, I didn't know Packard Bell was still making computers. I would think they sold you a bad battery. I've purchased new batteries before that would not charge.

first try to use your charger into another laptop, if the the another laptop was charged using your charger, it means your battery is the problem, but if it is still not charging it means the problem is your charger. then try your battery to use it into another laptop, as same as the i mention in the charger, if they or both fine, maybe the problem is the batery terminal of your laptop.

have you check the charger? or is there a power on the outlet? try to charge it from different power source

The battery of this camera can't be charged using the universal charger. Please purchase the compatible charger to resolve the issue.

If you have another power charger try it. It can only be one of two things. Bad charger or bad battery. Most likely the battery will need replaced

did you have a look at the sticker under laptop to see what voltage it was then set the charger to this,, if to setting is to low it will do this but if to high it could damage the laptop ,, you will find that it set to low or the other problem is most dells wont run via uni chargers unless the charger states it because dell like to use there own parts made by them unlike other makes

I'm not asking if the computer will charge, I'm asking if when you have it plugged in does the computer operate normally. You should be able to take the battery out of a laptop and plug in the computer in and the computer should still operate.

Okay, It can be 1 of 2 problems here:

1. Your laptop battery is completly dead, this can be caused by the overcharging of the battery, You may need to buy a new battery.

2. The battery charger is set at a voltage that can keep the laptop running, but not charge the battery at the same time, try a different charger (universal)
