Acer Aspire 7740-5691 :: Boot Screen Freezes With Pixel Distortion At The Top - Reset BIOS
Oct 21, 2014
I have an Acer Aspire 7740-5691. The boot screen freezes with pixel distortion at the top. I've tried all the restore discs. I found where some people referenced a similar problem with other computers and they were fixed by resetting the bios. I can't figure out how to do that. There's no place for that in the boot settings option and there's no visible coin battery to temporarily remove to reset.

I had my notebook evaluated by a local technician who told me the trouble I was experiencing was due to the DVD disc not recognizing and communicating with the computer. Upon further investigation she determined that the drive did read and play audio just fine. Video and graphics (pictures) would not play on the drive. Her conclusion was that the drive had a defect of some sort related to the DVD function only.
I have two questions.
1. Could it be that the ROM is corrupt and can that be replaced?
2. IF I have to replace the drive can I do that myself or do I have to have a professional do it??

I returned from windows 8 to windows 7 64 on my Dell Studio 1749 because i had a Hibernation problem.
Now the problem is not solved, i've the same in my windows 7 64 (when the laptop hibernate, it freeze). I think it is a bios error, and i want Reset it, but, if i try to reinstall the last bios, installation program does not work and report: "the last bios is already installed).

So I just bought (came in yesterday) a brand new aspire v 15 nitro and now it often freezes and crashes/shuts down at boot-up. I turn it on i get the acer boot up screen and then it stops and after a minute or so and shuts down.
I have done some things to it:
-partitioned the hdd (150/800 GB)
-updated windows
-checked for updates through acer care center (only one intel update)
-installed: steam, origin (EA), firefox, openoffice, winrar, viper (plagiarism scanner wich i used on my previous pc) and a couple of games
-uninstalled mcafee
I did not change any strange settings, like disabling apps from start-up except for steam.

I recently sold my Aspire 5002 WLMi notebook to a friend who changed too many settings and mussed up the BIOS in record time.... 10 days. I got most back by using a restore point but noticed he had a BIOS password requirement for booting up. I went to change that and set the new password with blank fields....save and quit....reboot....
...and whoops. Neither does a blank field nor his old password work now. in hindsight, I recall it was odd how some of his BIOS options had been greyd out and realized he must have a supervisor and another BIOS password. Swears he doesnt remember what he did. Now, we're locked out with 3 tries and error code 00000.
I removed the CMOS battery but unlike desktops I've messed with, I cant find any jumpers or marked pads to short out. Read somewhere that Acer now uses some form of flash memory. I cant find any documentation on this and Acer hasnt answered my email. Most of their sites dont even list this version of laptop. I bought it in Amsterdam at the end of 2005 but their Netherlands site is only in Dutch, a language I cant begin to decipher.
Anyone have ideas on this or possibly a motherboard schematic with lables? I looked at lists for Acer MB's and theres not a single number printed on here that resembles those lists I found.

Today I was using my laptop (Acer Aspire 5742G) normally and then suddenly my screen freezes and turns off. The picture at that moment when the screen froze was covered with green horizontal lines and some small green squares and then the screen switched off while the laptop continued to operate normally.
I tried to restart my laptop, but the screen does not turn on, and looks like laptop is working normally because I can hear the windows login sound (led indicators for WIFI and read data from the HDD are working). I tried to connect the laptop and TV via an HDMI cable, but the TV does not get any picture.

I have an Acer Aspire 7740-6656 that shows no signs of life. I have tried removing and replacing the battery as well as trying different locations to plug into power. I have even tried removing battery and power supply and holding start buttom 30 seconds. Except for a green light on the power supply cord, still no signs of life. What if any are my options?

I have an Aspire 2920 laptop with Windows Vista Home Edition O.S. It starts and works fine except that after I was using it with an external monitor (a flat screen tv) on the option to use external monitor, it only now starts thinking the monitor is the flat screen tv and does not recognizes the normal laptop screen. The laptop screen is now "pixeled" and only shows like 2/3 of its total width. I've checked in Control Panel and it has the flat screen registered as the "normal" monitor, but I can not way a find to tell the computer that the monitor is the same as usual and not the flat screen tv.

Wife has a Dell Inspirion E1505 that keep freezing on the Vista boot screen. You know the one with the 3 yellow bars that just run across the screen right before you see you login name.
Well it just freezes and never gets past that screen. I walked her through reinstalling Vista over the phone and it boots from the cd and then loads all the drivers off of it and then goes to the Vista boot screen again and freezes..

I just bought an Acer Aspire 7740-5691. I really like it a lot, but the screen appears a little "washed out". The problem is that the screen can only be pushed back to an angle of about 30 degrees. The unit is designed so the screen can't be pushed back any further than that. If I put something underneath the front of the laptop to tilt the whole unit back, the screen looks nice with good color saturation.
My previous laptop (also an Acer) had a screen that would go all the way down to 180 degrees so that the unit would be flat. It was possible to adjust the screen angle to suit anyone.
I don't want to return the unit (14 day return policy at Staples), but this is going to bother me too much if I keep it. I have tried to adjust the color controls, including the gamma, contrast, brightness, but the problem is the angle of the screen.
Are all of them going to be like this, or is this some type of manufacturing defect that might not exist in other units?

I recently updated my bios on my R7-571 and it has caused me great woe. My computer will lock hard between 3 min and 3:30 min after bootup if I don't disable the WIndows Managment INstrumentation service. THis of course caused other problems on services that depend on that like LogMeIn. I need a solution to this. Either a way to downgrade to an earlier bios which I don't think is possible without a version of the bios updater that will support this, or a newer bios that addresses this issue.

I have an Elitebook 8540w laptop. I wanted to upgrade RAM memory from 2x2GB to 2x4GB. I bought not a kit of 2x4GB as i wanted to, instead I bought two 4GB memory chips from HP.
After replacing the modules the laptop does not boot up.
What has been done:
- Bios Default Restore
My first question is: i realize it is better to buy a kit of 2 matched chips, but is it a must?

You can flash the bios with the version 1.11 (1.09 unavailable on the Acer website).
Flash only the bios under DOS.

I updated my Acer Aspire 4752g's BIOS to use the BIOS_Acer_2.10_Windows.zip in the BIOS downloads in the Acer site and when my laptop rebooted it was stuck in a black screen. I've tried doing the FN+ESC and tried all the BIOS downloads in the Acer site but it still did not work.

i was wanting to install ubunu, but i can't get into the bios without a password. someone told me it's' a administrative password. someone told me it has nothing to do with the hdd password. i need to change the order of the bootup for this to work. id rather not pay for this. i also know removing the cmos battery won't do any good either. is there a cracker or patch i can use? i was gonna download the latest software for my acer aspire m5-583p laptop but didn't because it would ask for a password.

I just buy an Acer Aspire V3-371, then I delete all partitions in HDD and install MS Windows and driver for this notebook. Everything are OK until I ugrade BIOS form v1.05 to v1.08. Now, it cannot boot to MS Windows and shows me "No Bootable Device".
I try to reinstall MS Windows, but I see a notice "Windows can't be installed on this drive" with details "Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks".

The strangest thing has happened to my Acer Aspire 2930 laptop today.
I shut it down last night as I normally do, then this morning I turned it on and it wouldn't boot. It goes through BIOS and startup, but then it stops. It doesn't start loading Windows XP from the hard drive, it doesn't recognise boot CDs/DVDs. When I go into the BIOS, everything looks normal except the boot portion. There are several options there, but they don't say what they normally say. For instance, the first boot device, the hard drive, is completely invisible. What I mean is that the option is just not there, but when you move the selection around with the keyboard, you can tell it's supposed to be there. Look below for a better explanation. The other options are there, but they aren't recognising the devices. I have a friend with the exact same laptop and her BIOS shows everything as it should be. She's here now and I'm typing this on her laptop because I now have two dead computers here at home.
I don't get it. It's almost like the BIOS somehow became corrupted. I didn' t even know this could happen without attempting to flash the BIOS or something, and that's not what happened. I have never flashed the BIOS on this laptop. Not only can I not figure out what happened, there doesn't seem any way to fix it. I mean, if the laptop doesn't recognise any devices to boot from... I was thinking about taking it apart and resetting the CMOS, taking out the battery. I think that's the best I can hope for at this point.
I don't have any way of cloning the BIOS from my friend's computer so I guess the next step would be to get a new BIOS chip if the CMOS reset doesn't work? The laptop is unfortunately one month over the one year warranty. I read that there's a way to get the laptop to read an external USB floppy diskette drive regardless of the status of the BIOS, you are supposed to hold the function key plus the escape key or something when you turn on the laptop a couple of times, and then it magically reads from the floppy drive. I would have to somehow buy or get a drive, but I haven't even seen such things in years. Things I can try?
Here is what my BIOS looks like compared to my friend's:
Mine:
2. IDE1 :
3. USB FDD :
4. Network Boot :
5. USB HDD :
6. USB CDROM :
My friend's:
1. IDE0 : Hitachi HTS542525K9SA00
2. IDE1 : HL-DT-ST DVDRAM GSA-T50N
3. USB FDD :
4. Network Boot : Realtek Boot Agent
5. USB HDD :
6. USB CDROM :
As you can see, there is definitely something wrong with my BIOS and I believe that's what is causing the computer not to boot.

I just got an acer aspire timeline 5810tz, which came with vista, so i was in the process of reformatting it to have XP, which i've done several times on my previous laptops. When i changed the bios to IDE, which is what i read was the correct setting (perhaps this is where my problem is?), i found that i could no longer boot the computer or access setup, bios or the boot menu. When i attempt to do any of these things, the computer just sits on the logo screen.
i'm getting fairly desperate at this point, having tried a large variety of solutions, key combos, removing the battery, etc.

Flashing the bios. I have a Aspire 5810TZ. I boot it up and it just says 'acer' and won't go any further. I went to the download page for BIOS on us.acer.com and it has a zip file with 5 files:
JM4151135.exe FLA... GPC_V135.bin readme.txt FLASH.BAT
What do I do? I have tried copying the files to a USB and powering on with Fn-Esc held down. After letting go of the power button and holding Fn-Esc a different screen appears after 30 seconds. I let go and have given it 30 minutes but it is not doing anything. I have read online from other people the power button should be blinking. Do I need to rename one of the files.

My Aspire M laptop will not boot due to the 'boot configuration file being invalid', at least, this is what the 'Recovery' blue screen states. The blue screen offers to 'Press Esc for UEFI Firmware settings, but is not responsive. I've tried F2, F8, F10, Alt+F10, F12, Space Bar, Delete and Break to try to activate the BIOS interface, all equally unsuccessful.
I followed the instructions to purchase recovery tools from Acer, but without being able to access the BIOS to set the boot order, I've just sunk another $25 into a laptop that doesn't work. The cost of service exceeds the cost of the laptop, so I'm inclined to continue trying to repair it myself. If it cant' be repaired, there is little chance I'll purchase a new Acer to replace it as this has been a very frustrating experience.

Laptop still under warranty. I recently had a motherboard and HDD replacement. I wanted to install Windows myself, but the BIOS was set to UEFI, and I couldn't seem to boot off of a USB drive. So I switched it to Legacy, booted from the pendrive, and installed Windows just fine.
For whatever reason, I went back to try and change the setting to UEFI. Now the laptop switches on, but refuses to boot. I get a black screen, with no logo or any prompt whatsoever to access the BIOS.
I read a bit and seems I need to remove the BIOS battery, let the memory clear itself to reset BIOS settings to default, and try again? If it matters, I re-installed Windows 7 64-bit.

2 days ago I had trouble accessing the internet on my E1-570. Windows Explorer kept throwing up a fault and restoring the page. Eventually I loaded Safari and then Firefox and resolved to sort the problem with Windows Explorer some time in the future. This may be unrelated to what happened the next night. Started the E1 and got the usual "Acer, Explore beyond limits" screen and spinning dots, then got the login screen - input password then return. Spinning dots for much longer than usual then blank screen. I can see the cursor arrow so the screen itself must be functioning. Lights on the front are working - AC, battery and HDD. I have had the machine 14 months and it is used exclusively at home so has not been roughly treated.
