View Full Version : G74Sw Issue - Battery/AC Mode switch under load.

Thought I'd give a post here as well as the technical support page (it is still under 90 day warranty). I recently purchased a G74Sw refurbished, and I must admit its absolutely amazing. However, whenever the system load increases due to gaming, or other programs, occurs the laptop begins to switch between AC and Battery mode. To note, it also does this when no battery is plugged into the unit (No power down. Just multiple notifications of "AC mode"). I was wondering if anyone had a problem similar, and if anyone can tell me what the issue may be. I'm hoping its something simple like a bad AC adapter, and not something worse.

Thanks to any and all help that can be offered. Its an amazing laptop, and I don't want to see such a problem bring it down DB

Try this first

Go to control panel and fiddle around with the power options management.

I've tested both situations. With the battery in, I get "AC Mode" And "Battery Mode" alerts one after the other in small bursts. Without the battery in, it just repeats "AC Mode". I suppose I could go fiddle directly with the power management options. Anything in particular you would recommend altering?

EDIT: Without the AC adapter connected, I've so far received no alerts, but I'm unsure as to how accurate that is, given I think the system is taxed less when the AC isn't connected (games slow down, and the like). Also Power4Gear Hybrid is installed

Technically speaking "IF" this problem still persist even when the battery is in then the issue might be lose power connector.

Is there a good way to test for that? The power cable seems to have snugly fit into the socket, and the laptop isn't moving at all when these alerts occur. Only thing that I notice that could be triggering them is the system load increase/decrease. It almost always happens when I begin to play a game. Oddly, if I've been playing it for awhile, it usually either will not happen again, or it will happen later. It also seems to happen if the system load decreases. Say if I minimize the game window then go to a browser I had running.

Try switching to each different power settings and try gaming for awhile.

or reinstall the power 4 gear hybrid..

Btw i strongly suggest bringing it down the service centre for the tech guys to take a look.

Oh and at what % level your battery are? 95%?

Its happened both while charging the battery, and while fully charged. It's also occurred under both Entertainment and Performance power options. I'll give re-installing power-4-gear hybrid a shot. By the way, I hope you don't mind me asking where I could find information on the location of a service center I can take it to? Sadly I'll have to wait a few days regardless, as I'm without car (I had a lovely holiday car accident ^.^; Thing is still in the shop).

I would suggest UNinstalling Power4Gear. Take extraneous add-on stuff out of the loop to better diagnose the problem.

Just uninstalled the power4gear, and restarted. To test a hunch, I played Alien vs Predator 2010 for awhile, and even while running off of window's power modes, I had it switch between AC and BATT (noticed the screen dim to bat mode, and raise to AC mode. Only way I can tell it's happened while in a full screen game)

Sadly, I just did so. And the issue still occurred. I'll likely leave it off (but keep an installer) as I prefer the default windows tools anyways.

I DO however, thank you for the advice. I can actually game while on battery mode now. Any other bloatware I'm safe to remove you can recommend? :P

I took off everything that had ASUS name attached to it except ATK, since the keyboard backlight is nice and needs it to operate. The general advice around the forum too is to remove all of it except ATK.

I think the evidence is clear at this point.....amount of Asus bloatware is inversely proportional to system stability. For those with OEM systems (i.e., owners who choose not to do a clean install), you can get rid of all this stuff:

Note: I deleted some programs, like Cineplayer and Nuance pdf Reader, because I use other 3rd party programs instead.

Very Interesting! This shall henceforth be known as "The Brody Stability Principle". ;>{)>

And it is also interesting that out of the other 3rd party apps pre-installed on my G74SX, those 2 were the only ones to exhibit buggy behavior...

So now, I can never be accused of being unprincipled! :)

You actually tried the Nuance reader? I assumed that everyone...well, maybe not everyone, just everyone in the known universe....uses Adobe Reader. ;)

Also, did you use the Trend Micro trial? I never use those trial security programs, but it seems like I've heard that that one, in particular, has some issues.

Hi i'm having the same problem, the power switch to battery after a while playing a game. I noticed that the charger is 19v 6.3a, and that's the same description of the product in the official page but the input of the laptop says 19.5v 7.7a 150w so... if i buy a charger with the specifications of the input on the laptop rather that the one provided the problem will be fixed? (by the way english is not my first language if i wrote something wrong) Saludos desde Peru!

I'm still finding out about the problem myself (Asus is giving me hell about the warranty), but as far as I know it is a failing/underpowered AC brick thats the cause. I'll get back to you as soon as I find out for myself.

Sorry to reopen this discussion, but I'm having the same issue. How did you resolve your problem finally?
Thanks so much.
