G73JH battery 78% but powers off

Strange problem here. My G73JH won't run at all on battery even though it says it has 78% available. I also did a check on the capacity of the battery through "powercfg -energy" and it says the battery has around 83% of its original capacity.

However, I also noticed that although it says that it is charging and the charge light is orange, it stays at 78%.

I went into the BIOS and reset defaults, and I even reflashed BIOS 213. I also did battery pull + mobo reset with paper clip. And I've checked the battery pins....

Do you guys think this is a defective battery? Very strange.

 

If you have the Win 7 standard power icon in the notification area, does it have a red X (even on AC power) and does it say " you should consider replacing your battery". I know my battery is "on its last legs" when I run the commnand you used above it says
12 Errors
3 Warnings

(Mine dies abruptly at 40% remaining so I get one hour use how long can you run yours on battery only?)

 

Yeah I think it's defective, worth getting a replacement.

 

Have any recommendations for a replacement? I looked at neweggs (they only seem to have 1) but it's 4400mAh. If they make a 5200mAh version, it might be worth the extra few bucks for the nearly 20% increase in battery life.

Windows 7 suggests replacing, and I get less than an hour on a total battery savings power plan.

 

The asus estore might still have the battery.

 

Either way it's worth getting an original.

 

The notebook has killed a replacement battery too now. My guess is either there is something wrong with the motherboard (oh shock, a G73 hardware issue!) or the batteries are going into a shutdown state of some sort (maybe overloaded when gaming on battery).

I sold the notebook to my boss for one of his kids. The kid is trying to play games on battery. I never did this in the years I owned it and never had battery problems. Battery died shortly after kid started using it.

 

I bolded the part where it went all wrong.

Gaming on battery... Though it does depend on what kind of game he wanted to play. Either way, gaming on a battery... It's... ugh.

Anyway, I've had a similar issue with Lenovo Y480. It would just shut down at 51% of its battery level. Replacing the battery solved the issue.

 

Yeah unfortunately the kids and parents know zero about computers. I didn't think it could kill a battery but that seems possibly what has happened here.

 

Rapid discharging of a battery can kill it and that's what games do. Well, not flash based games, but that was kinda obvious.

 

If you want to find out how to kill hardware, give it to a kid and watch lol.

 

Nvm, not going into kids topic ~~

 

Hey I was overclocking 486s when I was around 12. I didn't kill things any more than I do today. Meaning not very often.

But then this guy has no computer knowledge whatsoever so the sky's the limit. On the other hand he's not likely to try to re-paste it with a complete disassembly. Heh.

 

Did you ever think about recalibrating the battery?

 

Both of these batteries would not power the notebook at all and would not charge. They were completely non-functional. I tried all sorts of tricks like pulling the BIOS battery, new BIOS flash, powering up with and without the battery attached, booting Linux, etc.

I got a replacement again and this one is working fine. I told the kid not to game on battery.
