G73JH battery problem

Hi guys,

recently windows started to say me I need to replace my battery and my unit is just one year old since I bought it. I checked it with HWiNFO32 and this are my readings:

Right now, I'm on battery but when I unplugged from the adapter the discharge level started in 60% (of full) and in lest than 10 min on battery the level decreased to 45%, like 1% every 30 seconds. After those 10 min, the windows battery indicator become stuck and after 10 more min of use is indicating I have 35 min remaining with battery levels at 100%!!! (during all this time I stayed in battery).

Finally, in the battery indicator a red cross appears and now I have no time remaining and the battery is still in 100% of charge... and windows is still recommending me replace the battery...

What can I do, the laptop is no older than one year.


Thanks

 

You should do the full discharge and then let it charge up.

 

Start by deactivating the sleep/hibernate when battery reaches critical levels and let it drain completely. Once it's fully drained, plug the laptop in and start windows. Let it charge to full and check what charge level you get. It might just need to be re-calibrated.

Dang, ninja'ed by Chastity by less than one minute i'd guess.

 

Thanks tijo and my lady Chastity for your prompts replies. I'll do a full discharge and lets see whats going on. After my post (still on battery) the indicators started to decrease from 100% to 92% in a couple of min (with no time remaining). Now is stuck in 100% again with 54 min remaining...

I'll reproduce a DVD playback to drained out asap.


Thanks

 

You could also start prime95 and watch the battery drain at a crazy rate . For more crazy, try furmark + prime95 on battery with the GPU at full 3D clocks. The fact that the battery indicator is going bonkers is a good indicator that all you need is to recalibrate.

 

replace your battery, wear level is already 68%

 

Yeah bleed the battery and full recharge it could just need calibrating. Otherwise that is some impressive wear you have right there. Congrats!

 

Yeah, if you managed to wear it down 68%, when you can choose your custom title, instead of notebook deity you should call yourself battery vampire .

 

Sometimes the microcontrollers on batteries go bad... and other times the EC can go mental and never work again with any battery even after a reflash and reset. If you see either of these scenarios you can try disabling all of the power management actions in your OS and just keep an eye out for the critical battery LED flashing.

Definitely try running the battery down and fully recharging it to reset the battery 'gauge'. I would NOT do this in windows since you can corrupt your filesystem by letting it hard-poweroff, instead I would run it down to around 10%, reboot and hit F2 and let it sit in the BIOS menu until it dies. Then fully recharge it and hope the capacity restores itself. Good luck!

 

Ok, I'm done with my testing and the battery became normal. I follow the directions given in this tread, so, I left the battery drain until the laptop was off and it was unable to turn on the laptop on battery. Next I plugged the AC, boot to windows and the laptop started to charge the battery with normal %s and also the "Battery Replacement Warning" was gone. When was full, I checked with HWiNFO32 and the wear level drops to 45%

So, I repeated the process so I let the battery drain out again to also check how long was the battery lasting. In Entertainment Mode, Wi-Fi on, browsing on you tube and gametrailers, screen all the way bright and always-connected wireless mouse (USB dongle) the battery last one hour before goes off. Usually last for me 90 min in this scheme and when the laptop was brand new, the same scheme last 1:45 or even 1:50 min, no more than that. During this battery period I checked the wear levels and it's drops to 14%!!!

So, I recharged again to full, the wear level now remain in 20% stable and finally, at least, windows is indicating the right charge percentage and time remaining with no warning ... yet ...

Thanks guys for the light.



Two notes:

Found this info for the G73JH battery calibration in the asus g73jh support page, which is not applicable to the G73JH because the option it's NOT available in the BIOS of the G73JH... lol

The battery replacement at Asus eStore website is $139.00... lol lol

 

I'm resurrecting this, just to add that i experienced a similar problem today, took two discharges to get the battery to behave, but it seems to be behaving fine for now. The funny thing is that i had 75% wear reported (25% reported now) in HWmonitor, but charge capacity was at 320% which meant that i was getting the battery life i should be getting, but windows was bugging me that i had to replace the battery.

 

I haven't checked with any programs, but my laptop wouldn't turn on with about 50%+ inside windows.. I'm going to try and resync it now, i really hope that it's not almost dead.. Would ASUS replace this under warranty? AFAIK i have 4-5 months warranty left!

 

Matt-Matt the battery is only warr. for 1 year. I was having an issue about 9 months after purchase, and they cross shipped one to me that died at 25% and I was charged for shipping
So I just kept my stock battery.
