Acer :: Aspire 7720- Booting And Sound
May 13, 2010
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.

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.

Dell Inspiron 7720Bios V. A07Windows 8.
Today when I booted up my laptop, it shows the Dell logo and goes to a screen that only shows me a few things. It says "Boot mode is set to:UEFI; Secure boot:ON" Then there are two categories, "UEFI BOOT: Network" and "OTHER OPTIONS: Setup, Diagnostics, Change boot mode settings" I ran the diagnostics in ePSA and it said there's something wrong with the video card. It gives error 2000-0332 - "Video memory -Video memory integrity test discrepancy"... when I searched for this code, it said the solution is "Flash latest BIOS, retry diagnostics."

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. The reviews I've heard about Acer's commercial technology were just great so I had no worries about taking a chance with a company that I'd never owned a computer from before. Turned out to be one of the best computers I've ever owned!

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.......................

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

I've had this aspire 7720-6381 for about a week and a half now. I've been very satisfied, and have even been content with the mediocre laptop speakers it contains. I wasn't expecting much in that realm anyways.
The problem I have is that periodically the speakers will make an annoying clicking noise. It's pretty sucky. Even worse, after a time all sound will screw up and a deathly fuzzy roaring sound is all that is heard.

I was concerned about slow page loading speeds with this new laptop. I had done comparisons with this new laptop and my Toshiba satellite A70, 2.8Ghz Celery, 768MB RAM, Realtec RTL8/810x family Fast Ethenet NIC.
I was concerned enough that I booked a call with an ISP tech who was here today. He tried several download tests with a test site provided by the company and found that the new laptop was download/transfering data at around 200-400Kb/sec while the old laptop was getting download speeds of 1.6Mb/sec.
The AV programs and firewalls were disabled for each of the tests. Tried updating the driver on the new laptop but it had the newest driver available.
I deleted the driver and rebooted with no better results. I have an email out to Acer as of an hour or so ago and am awaiting a response from their tech.
I believe that there is a bad ethernet card/circuit in this laptop.

last year i formated my acer 9500 laptop and got a normal home win xp. A couple of days ago i got a hold of my original acer system cds and i decided to restore my system back.
Everything went well until the install finished; I was in windows and the first time i restarted the laptop it didnt boot back in win xp. When its about to start booting windows it stops and all i get is a black screen and a flickering white small line on the top line. I tried reinstalling the original system again and the same thing happends; after the first restart it doesnt want to boot xp.
I started reading forums and found out that if i press alt+f10 it might fix the problem.
It worked, if i press alt f10 before it reaches the black screen it loads into xp. This is the only way i can load it. As i read i got the feeling i might have messed up my MBR.
Im not sure how this all works but i have a hunch that my laptop doenst know where my xp is when its supposed to load it and by pressing alt f10 it somehow temporarly fixes that.
Is there any way to permanently fix this ? Some pple said that if i ran a normal non-acer win xp cd and ran some sort of MBR fix it might solve my problems. Im getting a cd from a friend in a couple of days . Is there any other way i can fix my notebook before then ?
Its not a big deal if i have to press alt f10 everytime i restart but its annoying and i have a hunch ill run into trouble later on.

I was installing Windows 7 on my Acer Aspire 6920.
It had Windows Vista installed. I deleted all the partitions including backup (Yes I found out that was stupid), and tried installing Windows 7.
It wouldn install Windows 7 so I went back to Windows Vista. I found my recovery disk and it sort of worked. There where no errors in the setup but when I start my computer it doesnt go to Windows.
It has a black screen with a white _ blinking.

I have a brand new Acer Aspire 5536 Notebook. It came pre-shipped with Vista which I did not want.
So I tried a fresh install of Win7 - formatted drive etc,. Machine takes 5+ mins to boot so I put this down to a compatibility issue and tried XP. However I have the same problem, fresh install with only updates installed and it takes forever to boot (even longer than Win7).
Once booted performance is ok (in Win7 it was near perfect). Any ideas, I am beginning to think it is defective.

I have had my acer aspire 6530 since August 2009 now. It never had any major problems. Sadly, after comming back from New Years Eve 2014, I wanted to turn it on, but it just started up for around 4 seconds and then started to reboot again and continued so, until power was plugged out or shut down. There was only a black screen, without BIOS etc.I've searched forums for a solution, all of whom resulted in failure.

 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.

I bought an ACER Aspire 7720G Intel Core 2 Duo with Vista SP1 3 weeks ago and have now some problems with my WLan and with booting after sleep. WLan only works when I restart the computer after swiching on the WLan connection either by pressing the WLan button or by activating the connection in "networks and sharing center" (at least it works then, but it's annoying to restart the computer all the time). Since I use WLan at home I get a message while booting the system (Broadcom UNDI PXE.... Client... MAC ADDR:... GUID... DHCP ...not found..blabla). I use a Lan connection at work and here I have no problems yet. My second problem is that my computer really stays asleep after I woke it up from sleep or just if I would not use it some minutes. It does not show any system related information anymore and I can only restart it again. I have looked up my BIOS and it is Version 1.44 (read the thread about the BIOS problems),

Just bought an Aspire ES1-511. Not my first Windows 8.1 laptop, but my first with UEIF firmware.
Â
I've been trying to boot Driveimage from CD to do an offline backup, and guess what, it wouldnt recognise the CD as bootable. Fixed that by setting the boot type to "Legacy" in the BIOS and it boots fine.
Â
My problem is that the mouse doesnt work after booting from the CD. Watching the behaviour of the mouse, it powers up when I press the power button, but powers off immediately the POST completes.
Â
If booting Windows from the HD, power to USB is restored as soon as windows loads to the lock screen.
