I thought it wasn't really a big deal since I always use it with the AC, but recently when I am gaming the laptop just turns off. I can turn it on right away - so it seems it loses power for half a second or something, which is enough to turn it off.

Seems like my battery serve another purpose than running with no AC. And it also provides extra current during high demand usage like heavy gaming, and also carry my computer through brownouts. In my case this prevents me from actually using the laptop for other things than browsing...

I have tried to uninstall the battery drivers, tried holding the power button on for 60 seconds. Next step is to reset to factory, and reinstall windows 10. Would also like to flash my BIOS, but I guess I can't do that since my battery is at 0%.

Anybody managed to fix this without opening the thing and replacing it with a 100 euro battery?

Thanks

im from Latin america so send the PC to a good technitian its dificult.

Saludos Desde Guatemala!

There is the images, Y gracias por los comentarios

there was 2 electonics

1- a micro recistance

2- was the IC who i dont know (and Trying to find with your help)

PS: The LCD wire was my first idea but when i saw the Missed IC and the are of it was y dettected the problem, rear the Missed IC area are the coneccion to the LCD screen

PD: El problema de pantalla fue mi primer idea, pero cuando vi que faltaba el CI detecte automaticamente elñ problema ya que detras de ese integrado va el cable hacia la pantalla

I have to pound on most of the keys to get a response, the wifi keeps disconnecting, and my right button doesnt work. Im thinking its the motherboard, but how can I know for sure?

My laptop is 3 years old and since 1 month ago the noise is outstanding. When it boots it is silent, but few minutes later the sound is incredibly loud.

I need to clean the fans, but how to do that?

I’m not sure how to diagnose this. Bad charger? Bad charging port? Bad motherboard? I saw on ASUS’s ROG forums that many people have trouble with their charge port but the cheapest one I saw online that didn’t look like a scam was $110. I don’t want to just have to guess and end up buying the wrong thing, as parts seem to be pricy so I want to make sure to get the right thing. I don’t have any multimeters or anything either. Maybe someone more experienced can guess as to what the problem is?

Hi,

The laptop stopped suddenly while in use and since I couldn’t start it again. No lights on even when plugged in. I tested the power supply and the multimeter indicated 19.5v as expected. I also tested the battery (not sure though if it is meaningful) and the expected voltage was what I read. I replaced the CMOS battery (I don’t know if this was necessary).

I need some guidance about what to replace. Which tests can I perform to identify the culprit? A new motherboard is pricy. My battery is old (5 years with daily usage), can a dead battery prevent the lights from turning on and the laptop too? Is it the DC connector? How can I know?

I hope someone can help.

TEST RUN 1:

From my first test run, I tried to play Company of Heroes 2 on the lowest settings. Today it only flickers to battery sometimes. Here is a GPU-z sensor log from when it happens. You can see at the 30 second mark I alt-TAB into the game, and it changes to battery for 4 seconds. As you can see from the picture below, the GPU memory clock changes, as well as the PerfCap. (Note: this flickering to battery happened in the game maybe 5 times in a period of 10 minutes, and also in Windows when I am opening folders and Chrome.)

TEST RUN 2:

So I tried Heroes of the Storm with high graphics, and the laptop shut off after a few minutes in game. Actually it shut of while we were loading into the game (after the hero select and the menues). As you can see, the GPU Load [%] , Memory Controller Load [%] is very low right before the shut down, because there werent much graphics, only the load screen.

One more thing to note is that when I boot up the laptop again, I can clearly see that it stays on battery for a few seconds during the ROG logo (before windows boots). I can see this because I have 100% brightness on battery and 0% on AC. (When I tried to boot without the battery yesterday, it wouldn't even boot into windows).

TEST RUN 3:

Heroes of the storm with lowest graphics. 30 minutes in-game, with actual gameplay and no shut downs. Changes to battery approximately once a minute for two seconds.

At about 28 minutes it changed to battery, and didn't change back. I turned off the computer manually and when I was back in windows, it recognized the AC again.

Since I am not able to view .CSV files, the only thing I notice from the GPU-z logs are the GPU Memory Clock changing to 799.8 and the PerfCap Reason to 1 during the AC disconnect.

TEST RUN 4:

So with FurMark there isnt much to say, I run it, and it shuts down before the graphics appear.

A few hours later, I can’t detect either smell from the installed battery, even when close up. The inside of the (closed) battery bag still smells like sort-of-grass/toxic-chemicals.

Problem: Is this safe/normal? The battery doesn’t seem to smell now, but the bag’s inside still does. I don’t think that either smell was sweet/acetone-like.

Question: Is wrapping each exposed wire of the battery cable with electrical tape okay? Aside from the added bulk in a tight space.

Thanks!
