Old Asus Laptop Plugged In, Charging 0%

Have an old laptop asus u45jc-a1. I haven't used this laptop in a while since its i3-370m processor and thus slow for what i do. Well i recently powered up this laptop and then put the charger in it...


I get 0% available, plugged in, charging. Basically that means the moment i unplug the charger, the laptop immediately shuts down. Thus even if it has a few minutes, that would be okay. I had bought a replacement charger on ebay a while back for pretty cheap, it was under 20 dollars i recalled. It worked for a while but i never really used this laptop but got charger mainly because well the asus laptop still works and thus just get a replacement charger.


Does this mean my charger doesn't work? Or could it be possibly the battery?


I see a thread here a while back where someone fixed it by going to this and uninstalling it. Is this safe to do? It ask are you sure you want to delete this and well... that seems to be important.

"Plugged In, Not Charging"


Thanks.

Hi... well i dont want to try it in case something bad goes wrong. Thus i want to know are there any other alternatives first.

it not going to hurt anything to uninstall it. you should be fine. I would try what was suggested.

okay but any other alternatives? I didn't like that message since it seemed okay that means i have to download it again and not sure where to dl it from.


Someone in another forum said i could check to see if my battery is actually defective using some program called hwmonitor and hwinfo? Anyone has done that before?

i downloaded hwinfo64. someone had mentioned to download this to test battery. When i went to battery, it shows battery number 0 and shows


Designed capacity 84000 mwh
full charged capacity 61815 mwh
wear level 26.4%


power status critical on ac power
current capacity 0 mwh
current voltage 5.908v

I would power off the notebook, plug in the charger, and leave it alone for a few hours, then see if it works.

Does this mean my charger doesn't work?

Will it power the notebook with the battery removed?

Do you mean if i remove the battery, the plug in the charger, does my laptop work? If so... yes it does.

Okay, then that suggests either the battery is bad, or it is so far discharged, it is trying to draw too much current from the charger to support both the battery charge and running the notebook. If the battery is bad, you have no choice but to replace the battery. If the battery is still good but is really deep discharged, plugging in the charger but leaving the computer off for a few hours (or even overnight) may allow the battery to charge enough (or even fully) so it will cut back on what its demanding from the charger, and allow you to run the computer with the battery installed.

Note this is because all batteries attempt to draw as much as they can from a charger when they have been deeply discharged. Then the more charge they take on, the less they demand from the charger. The closer they get to fully charged, the weaker the demand on the charger. This is exactly why, BTW, chargers are always rated at a higher voltage than the batteries they go with. You have a 12V battery in your car, for example. But if you checked the alternator/charging voltage, you will see it typically is between 13.8 and 14.2VDC.
