Acer Aspire V5 552 gaming performance slows downs when plugged in to the charger (HELP!)

Are you sure that the charger is working good?

there 2 options here:

1) Power Options not working good, check in Control Panel - Power options

check if you can "force" highest performance and try again with and without charger

or check advanced settings with AC charger connected

2) the AC charger output is not correct, maybe giving less wattage or amperes to the notebook.

The charger is working as it should, I even tried with a generic charger and its the same result..

How do I exactly force that in power options, because when I go to change my power settings on the profile am using everything is on max, but under ATI Graphics Power Settings>ATI Powerplay Settings on battery and plugged in both have maximize performance, but when plugged in with maximiza performance the results still the same, fluctuating cores and not staying at 2.8 GHz, however when setting plugged in to Maximiza Battery Life it stays at default speed 2.1GHz but still framerate is not good.

When on battery is set to maximize performace it would stay at 2.8 GHz turbo mode and the cores would not fluctuate. I really dont know what is causing this...

As power option, i mean the windows power options not the ATI power options.

By the way is something wrong on the cpu frequency control.

Years ago i used a program to set it manually but i can't remeber the name.

nothing wrong with it, the only time that fluctuates like that while plugged in and using the maximize performace is when I play games, and yes I also tried the windows power options with no luck.

Are you using drivers from Acer website or ATI website?

Yes official drivers all up to date

Can you check on BIOS (press F2 at boot) if any power setting is available?

if so, set to maximum perfomance, disable cool&quite or C1 and C6 state if any.

about AC charger, the generic charger has the same specs?

No power settings avilable, only options I found were Quite boot, network boot, and so... the generic charger has different voltages, I can set it up to 24V, I tested using mu laptop with that, and the cores doesn't fluctuate as much as before but still fluctuate between 1.7 GHz (the lowest I saw) and the max 2.8 GHz, still better performance and stable 2.8GHz when unplugged.

I´ve got the same problem dude, it´s a BIOS malfunction, but Acer won´t do anything till we make some noise, look at this thread: community.acer.com/t5/Ultra-Thin/Performance-slow-when-plugged-in-V5-552/td-p/202767...

Lenovo user got their problem solved with a BIOS update, i´ve been contacting support and they only make excuses and repeat the same: Are your power settings on high performance?. never buying Acer Again.

Has Anyone Solved this issue?

I have exactly the same problem with the same model V5-552M laptop works fine when on battery but FPS drops from 100 down to an unplayable 10 - 20 when charger is plugged in on CSGO although this effect happens on all games, its not the power settings, updated drivers, re format, update bios. It has been for repair twice and has not been fixed by suppliers and everything replaced including battery and AC charger. Still the same

Any news would be helpful

Mine is a V5 55p x684 A10 5757m....been already 3 times on repairing, and THEY HAVE REPLACED THE FULL MOTHERBOARD....so this is a Software issue, We have to flood Acer with complaints so they make a solution as Lenovo did...A YEAR AGO.....I WANT MY COMPUTER WORKING NOW!!!!!!!!!!!!

been trying here a lot of things too...nothing...different chargers, power plans, voltages, nothing works...

Yes you are totally right, we Acer users have to start to make some noise and make our voices heard, I just noticed this issue few days back...and wasn't aware how much of great laptops for this BIOS issue are being left with so little when they can perform and do a lot more, there has to be a way to make Acer aware of this...

And where are the Admins and Acer People? You are loosing customers each second.

I really don't know...but they have to listen now this is a mayor problem...its bringing good products down...as well as costumers

Acer fix this BIOS issue!

Please an Acer employees or someone from Acer, take note of this, users of the A6, A8, and A10 processors are having performance issues with their CPU's due to a malfunction when the charger is plugged in, the performance while gaming decreases to the lowest frequency and with a lot of fluctuation, all this because of the BIOS, please release a new BIOS update to fix the issue.

Thank you.

Hi FIPOLINIO,

It sounds like a power setting to me, if you're getting the same results as the video you posted, something is happened that's throttling the system when the AC Adapter is plugged in. Try this and tell me your results please.

Windows Key + C to open Charms
Select Search
Type Control Panel and select it
Select Hardware and Sound
Select Power Options
In the right hand menu select Create a power plan
Select high performance (name it if you'd like)
Click Next
Click Create

You should come back to the Choose or Customize a power plan screen. Your new custom power plan (whatever you named it) should be selected. Go ahead and close out of that, reboot once just for good measure and then see if your games continue to have an issue.

Hope this helps,
Cory
