CPU, BEEP Issue... Help

Bought a refurb laptop its the acer aspire v3-771g  it was a solid deal and understand the risk of refurb.  But let's cut to chase.

It has the i7-2670QM processor.  I am finding out that it will beep and then stop charging, screen dims and then comes back to normal (all that in just 1-2 seconds).  This occurs when the CPU hits max speed.  So one thing i did was make cpu max slate 99% and this solved issue so to speak... BUT I want to know how I can just get rid of beep and such and leave it at 100%  Anyone know why this is happening and how to fix it??

I hope someone has a better way to fix this?

no it doesn't randomly spike it will spike during loads and such not randomly sorry.
 

all up to date and it still does it.  It starts doing it during Guild Wars 2 when the cpu is being used a lot
 

No overheating issue i been watching that.  The best way for me to explain what is happening is when the cpu hits its max like during a game it the speed will bounce around and when it hits that 3.1 that is when it beeps and "trips" not really trips but the charge thing happens.  then when it is off of 3.1 it goes back.  so when I make it max 99% rather then 100% it never happens.

just want to add some more info.  I had the turbo boost management when the beep and "trip" happened except this time it didn't come back to charging mode.  so I minimized guild wars 2 and when I do that the start menu was up as well.  THIS is when it began to beep consistently with a little time in between maybe 2-3 seconds then go again.  i watched the turbo boost and it was not at max.  but i did see that the engery saver leaf was coming on and off with the beep and also see that the start up menu "shut down" button was going from normal to administrative icon on and off next to it... so I went into power again and made it 99 and it was "fixed"... lol

here's my convo with acer... not sure I believe it yet..

Vignesh RB: Hi, my name is Vignesh RB. How may I help you?
Vignesh RB: Hi, Andrew.
Andrew Benak: Hi
Vignesh RB: How are you doing today?
Andrew Benak: I am having an issue with my laptop and have been trying to solve and can not..
Andrew Benak: I will try to explain it the best I can so bare with me
Vignesh RB: Andrew, for better understanding, may I know the exact issue you face with your Notebook?
Vignesh RB: Please proceed.
Vignesh RB: I am waiting for your response.
Andrew Benak: When under CPU and Graphic demanding situations for example Guild Wars 2.  The computer will beep then dim the screen, with say it's not charging and then come back to normal
Andrew Benak: Now one way I have gotten around this is I go into power management and set CPU max slate at 99% and it NEVER happens but when it is at 100% it will occue
Andrew Benak: occur*
Vignesh RB: Andrew, I understand that the computer will not take charge when you play games in it. Correct?
Andrew Benak: no
Andrew Benak: it will just cut out for a second or two
Andrew Benak: then come back
Andrew Benak: and it will do this off and on sometimes 30seconds in between sometimes 1 minute
Andrew Benak: but when I am not gaming or under a high CPU usage I have no issue
Vignesh RB: The Notebook does this only when you play game in it. Correct?
Andrew Benak: Usually is during games but have had it happen when under high CPU usuage
Vignesh RB: Andrew, I will help you in the right direction.
Andrew Benak: heating is not an issue tho.  It will happen right away during the game there is no way the CPU got that hot that fast
Vignesh RB: I understand.
Vignesh RB: This will happen when the game interface occupies the CPU space and there are no trouble shooting steps to prevent this.
Vignesh RB: Andrew, the game which are playing in your Notebook has high graphics part and that may require more graphic card performance.
Andrew Benak: the game is performing great there are no issues with the game.  I don't get why this issue happens when the cpu max slate is 100% and wont when its 99%
Vignesh RB: In this case, you can either contact the game developer support or the Answers by fee based support through 8775264466.
Andrew Benak: that sort of proves your theory wrong
Vignesh RB: Even if it is an computer, when the work load goes high the performance of the computer will go low.
Andrew Benak: Right.
Andrew Benak: But
Andrew Benak: why is there NO issue when max slate is 99% ?
Vignesh RB: It is not that it will stop working, it will work but it will take some more time to finish the assigned job.
Vignesh RB: Andrew, the computer memory is not full at least it has 1% to breath. When the total space is occupied it will not have space to run the assigned job.
Vignesh RB: I do agree with your point, there is not a huge difference between 99% and 100%. But, in this case it makes a huge difference in performance basis.
Andrew Benak: The laptop has i7-2670 quad core with 8 gigs of memory and 2 gigs on graphics card.... how can there be this issue?!
Andrew Benak: I mean I see what your saying but feel that it shouldn't have a problem with these specs is all...
Vignesh RB: I understand that, even if it has 8GB of memory the game occupies the whole RAM space and that will cause the issue.
Andrew Benak: hmm ok well I guess I am glad this is not a big issue.  Yet a little upset I have to set it at 99%
Vignesh RB: Andrew, the Notebook will not run the entire games memory. I believe that the game will be of 2 GB , but the RAM will run only with the 8 GB of space it has got.
Vignesh RB: I do understand your concern, as a customer even I will feel the same.
Vignesh RB: To conclude, we have provided you information regarding CPU utilization and this should help you fix the issue. If there are no additional questions on this topic, I will close the chat session.
Andrew Benak: I have one more
Vignesh RB: Please proceed.
Vignesh RB: I am waiting for your response.
Andrew Benak: so this is COMPLETELY normal and there are no issues at all?  Right now laptop is under warranty but if I have an issue that is based around this after warranty I will not be happy... I also will be saving this conversation to back me up in proving I tried to have it fixed right now.
Andrew Benak: If your willing to say everything is ok and I should leave it at 99% that I will trust you and go on my way
Vignesh RB: Andrew, I understand your concern and I completely agree with this.
Vignesh RB: For your security I will send a copy of this chat transcript to abenak89@gmail.com
Andrew Benak: perfect! thank you!
Andrew Benak: that is all I have for you ha just am glad its not a big issue
Vignesh RB: It is my pleasure assisting you and your satisfaction is my primary concern.
Vignesh RB: Andrew, it was pleasure assisting you today. I appreciate the patience you presented while we worked together on this issue. May health and happiness be yours in all seasons.
Vignesh RB: Thank you for contacting Acer live chat support.
