Acer :: 7720: Power Settings - When Unplugging
Dec 15, 2008
I have an Acer 7720-6604 notebook. For Power Settings I usually keep it on "High Performance" when plugged in (I'm usually gaming). I've found that when I unplug it with this setting, it acts like it's on "Power Saver" mode, which equals a big drop in frame rates when I game. I checked out event viewer and it shows this message as associated:
"Event 2, Kernel-Processor-Power
Performance power management features on processor 1 are disabled due to a firmware problem. Check with the computer manufacturer for updated firmware."
I've looked all over and can't find any way to fix this problem. I really haven't seen anyone else have the problem actually. It's bad though because it really makes games unplayable and shouldn't be happening on a relatively new laptop (bought it only about a year ago). I don't know what firmware I need to update or what I need to do if that's not it.
I did uninstall all of the empowering technology programs, including epower management. I'm not sure if it's related... I thought it was just a power scheming tool and windows has it's own in the control panel anyways.
Someone please help. I don't want to have to format or send it in for repairs if I can help it. Acer has an expensive repair fee (so I hear). I will format if I have to but I don't know that it will fix anything.

I'm having an issue where my lappy completely freezes up when it is on battery power. It will boot off of battery fine, and I can click to the desktop, but then all icons become unclickable and all keys/input functions cease to work, and after about 30 seconds, the mouse won't move anymore. If it is on and then unplugged, it instantly freezes. I checked and I have the most up-to-date bios and drivers. I'm a bit perplexed as I've never run across an issue like this before.

 My battery has not held more than about a 45-second charge since 2009; however, the AC adaptor seems to work fine, and the Power Management icon always tells me that I have a full (i.e., about 45-second) charge and that the AC adaptor is plugged in.  Today, just after I disabled the Acer Tour Reminder, CyberLink PlayMovie, and Microsoft Office OneNote (because I never use them and I wanted a faster startup), I moved some program icons that I didn't need or that were already on my Quick Launch tool bar into the Recycle Bin.  Suddenly, the notebook make sort of an electronic squeaking sound and immediately shut down--black screen; no lights. Â
Â
I unplugged it, checked to ensure the battery was properly seated, felt to make sure it did not feel hot anywhere, plugged it in, saw that the lights were showing on the adaptor and on the front left edge of the notebook, turned it on, and selected normal start; it started up again.  It ran for at least three minutes (which, because of the battery, it would not unless the AC adaptor was functioning) and then, after I moved a few more icons to the Recycle Bin, it suddenly shut down again in the same manner. Â
Â
I started it again and it has now been running long enough for me to look up my Acer Forum registration information and update it after resetting my password. Â I am writing this on another notebook. Â The Acer is still running, but I want to ensure it doesn't shut down on me when I am in the middle of a project.

My laptop turn will not power up, circumstances I shut it down yesterday, packed it up, when I tried turning it on an hour later at school I couldn't get it to turn on.Â
Is this a hardware issue that can be repaired?
Computer: Inspiron 7720-17R, i17Rse-3589BK, Intel i7-3630QM
A. I have checked the power chord it works on my older backup Inspiron17, I two power adaptors the work. the original Dell and an after market rocket fish. both work on my older model Inspiron 17.
B. Without the power chord: open the lid, press the power button, it does not turn on the computer on or light up, none of the indicator lights do not light up.
C. When I plug the power adaptor in to laptop:
1. the power indicator light on the laptop does not light up showing it is plugged in.
2. pressing the press the power button it does not turn light up or turn the computer on,  none of indicator lights do not light up.
3. (Original Dell power adaptor) the blue light at the end of the power chord goes out.
4. (Rockfish aftermarket power adaptor) the blue light on the adaptor goes from a solid blue to a blinking blue light.

When i press the power button laptop seems to be powering up and running but the screen is black. The LEDs for power and disk are on and i can enable the keyboard back light. If i try to turn the laptop on again and again then after some time it boots up ok and then works without any problems, at least until i turn it off. I tried to connect an external monitor but it didn't get any signal.
I'm not sure if it is connected but i think it starded after i did the system recovery. I use Windows 7 Home Premium SP1.

Laptop is on and plugged into the docking station which is "powered". Â Connection to monitor / keyboard and mouse is fine, however I'm surprised to see a lower power - plug is soon message. Â Isn't docking station supposed to provide power to the laptop?

Just wondering what we use in terms of Power Management, whether its part of the OS or its Dell's Control Point Manager, and whether it affects the fans kicking in or not under comparable settings.
I use an M4400 & an E6400, both have the latest BIOS revisions, and both use Vista's native applet, selected to "Balanced".

I have a Dv6500 series notebook with C2D 1.5 GHZ processor and Nvdia 8400gs Graphics card.
My notebook came with vista preinstalled which i did'nt like...
so I Installed XP primarily using the guide at this location
www.nogodforme.com
and
Installing Windows XP on the Intel based dvx500t Series
I have installed all the drivers mentioned in the thread and I dont have any "yellow" marks in the device manager...
The problem is With Vista there was a toolbar option that displayed "battery level", "charging status" and allowed to use the following settings
1)Power saver
2)HP recommended
3)High performance.............

I bought this computer on Jan. 1st and so far I love it, however, a few days ago I noticed that everytime I connect or disconnect my charger the screen goes black for a few seconds. Â It's not the worse problem however it is extremely annoying! Â I tried checking both the intel graphics settings and power management settings to see if an adjudtment would work but it has not. Â

After a smooth clean installation of Windows 8.1 and loading all the Lenovo drivers, software, and apps, the system runs extremely well except in the Lenovo Settings Metro App, I no longer see the option of battery life protection (to charge only up to 50%). In addition, in the Windows power settings, there are only four power profiles: high performance, balances, power saver, and fly mode. Â I do have Lenovo Power Management Driver and Settings Dependency Packages installed. Â Lenovo's System Update does not show any missing installations.

The other day I tried gaming while on battery and got terrible frame rates. I had the power settings on Maximum Performance. Are there other settings I am missing?

I have downed to XP and everything seems to be fine. All standard functions work A-OK!
The MOTU audio drivers are loaded (same drivers I use on my desktop PC) and viewable via the CONTROL panel in the SOUNDS section. I get absolutely NO Windows sounds at all. If I change back to the REALTEK, it works just fine.
I have added an ExpressCard Firewire card for the MOTU interface and it uses the T.I. chipset that MOTU advised me to use. Yep, I am using the same cable that I use on my desktop PC.
I was also advised to disable the RealTek sound in the BIOS, but when I accessed the BIOS I found there is NO system settings tab at all. I have also been told to uninstall the integrated Firewire port via the BIOS. What gives here?
I have used the SYSTEM/DEVICE MGR/ to "disable" most every item listed (one-at-a-time) then tried the sound test again, but nothing has helped.
So, my current plan is to flash the BIOS to 1.43, it is currently 1.44 InSydeH2O v3.0.
So, I am not sure if I can use the 1.43 Bios code.

I have been looking for Acer 7720 hotkey drivers but in vain. Can a good soul direct me to an appropriate place to look in? I've looked on Acer's driver download page but it doesn't list anything regarding hotkeys. Btw I'm running windows 7 (if you can find a driver for vista, it'll do).

I purchased this model because of the right balance of power, memory, storage space, and battery life. The great video card was a factor as well.

Turned out to be one of the best computers I've ever owned!

It seems Acer has disabled the Intel-VT support for the Acer 7720 in the BIOS. I;ve installed the 1.43 version of the BIOS, but no difference.
I;ve created a support request with Acer to ask them for enabling this option, which makes it possible to run an hypervisor like xen, kvm or hyper-v. At this moment it does not seem possible to run these. This would enable us to have almost native virtualisation of several OS's.

I been looking to upgrade my CPU and would like to know what is the fastest (MHz and cores) CPU that my 7720 can use? I am looking at the q9900 or extreme quad core socket p CPU to up grade to. Yes I get my jollies off of stressing the maxium capabilities out of a laptop. I have a Acer Aspire 7720-6556 or somthing close with intel core2 1.66 with 17in LCD and 2 500 western digital scorpion blue harddrives using MS Vista for OS with 2 gig of ram BIOS 1.45. Whew! I've tried windows 7 poor support for intel video and ram and no ir drivers. Oh back to the point, I am looking for to find out if this laptop will support quad core tech and what is the fastest CPU that BIOS ver. 1.45 will allow,

I purchased my Acer in Dec of 2007. It's worked great except it's overheating problem (got a fan, no more problem). Last month it started intermitently not booting properly, and not coming out of sleep. I "fixed" the sleep problem by telling Vista not to put it to sleep any more. I typically shut it down when I'm finished with it so sleep wasn't an issue for me.
To ellaborate on the booting problem. If I attempt to boot it, the display turns on, and power button turns green, but neither the fan, nor Drive turn on, nor do any of the USB ports get power (I know this because I have an illuminated keyboard, which doesn't illuminate when this problem is occuring). I've waited for as long as an hour and it will never boot. If I hold down the power button for 4 seconds, it turns off. And if I boot it again it boots up properly. Doesn't matter how many times I reboot it after it always comes back up. I've never tested how much time passes before I can't boot it. I also tryed putting it in hibernation manually, that worked twice, the last time it wouldn't wake and had to be rebooted. I've done a check disk on it but all seems fine.

I've uploaded my referenced screen grabs here since I ran into difficulties last night. This seemed like the logical solution.
I bought the Acer Aspire 7720-6395 yesterday. I couldn't find any reviews other than those on Best Buy's website (a couple are okay, but none comprehensive), so I hope to contribute to anyone else who might be considering it but unsure. I live an hour from the nearest big city, so any additional details would've made it easier to make the drive.
Forgive me if there are details you don't need or none that you do. I'll do my best.
I won't repeat the specs that Best Buy gives on their website, but I'll shed light on a couple that aren't clear through writing or screen grabs.
It seems that a number of people bought it thinking it had a Blu-Ray writer (BB had something on their site saying so, apparently), but be sure you note that it is only a Blu-Ray ROM drive. I say only...
Oh, and it is also a dual layer DVD writer and CD writer.
It has an integrated webcam and microphone if you're prone to video chatting.
The speakers are in a strip directly under the power and accessory buttons. It boasts "DOLBY DIGITAL LIVE" above the mesh, but they sound like most other decent laptop speakers. Not great, but pretty good all things considered.......................

Acer Aspire 7720 I've got. Basically it has both the common boot-up freeze and crackly/distorted sound problems that appear to be common. I understand that the best, albeit riskiest, way to solve these is to flash the bios to a more recent version, which I am prepared to do.
However - the bios upgrades are not available from Acer's own support site, and I don't know where else I can find them, and I have tried.... Is there anyone who can help me locate them? The problems with this laptop are driving me spare, and I really can't afford another, or even another motherboard, just yet.

My aspire is as per topic title a 7720 T7300 (2.0ghz ,800mhz FSB , 4mb L2 cache)
I am running a recent Bios flash so up to 1.43 spec.
Is a CPU upgrade to a T9300...simple just a case of processor pull and new CPU refit?
Will it be of benefit or worthwhile in the firstplace?
As i can get a Intel®Core™2DuoMobile Processor T9300/2.5GHz/800MHz/6MB
