Acer Aspire 4752G :: Do Restart Instead Of Shutdown Since Windows 8.1 Update

Oct 4, 2014

I cannot turn off my acer laptop since windows 8.1 update.. whenever i do shutdown, it simply just restart after shutting down.. i dont know how to turn off my laptop.. also sleep and hibernate seems not functioning, in a couple of seconds it awakes again..
I tried the every thing about the power management to untick something about fast startup.. still no luck
And i forced to shutdown my laptop during startup but it cause me a problem.. It wont power on.. and it seems dead but when i plug the power adapter the battery is charging but no signs of powering up(no power led, just battery led) whenever i press the power button.. i tried dispersing the static electricty but no luck.. the only option that solve my problem on not powering up is to disassemble my laptop and remove cmos battery. then i assembled it back.. it shows 1 blink of power led whenever i plug in the ac adapter without the laptop battery plugin.. and then it powers up again after i press the power button.. what a relief.. but it doesnt fix my shutdown problem..
the only thing i havent tried is BIOS update.. but im having problem right now..
i tried last year to update my BIOS after that it went wrong the black "screen of death" they call.. so i sent my laptop to service center.. and it fixed!..
I tried lately to update my BIOS but it says that i have already an updated BIOS version 2.19.. i guess this is the bios version installed by service center.. how can i apply the BIOS posted on ACER website with the latest version 2.15?
If i want to turn off my laptop, i simply close the lcd monitor to remain it in sleep mode..

Lenovo P/Y/Z Series :: Z510 - Default Boot Device Missing Or Boot Failed After BIOS Update

Dec 13, 2013

I get the error in the Title after i tried to flash the latest BIOS update for the Z510. I can press ok and then get into the boot manager but i cant choose anything there. Also I cant boot from a Disk with e.g. XP on it.
I also tried the Inside BIOS crisis mode (fn+r) with the BIOS file on my USB drive but it doesn't work and tries to access the file on the USB drive but boots normally instead to the error again. (Couldn't try it with removed battery as I have to remove the whole back to remove the battery on the Z510).

Acer :: Aspire 7720z - Bios Update

Apr 23, 2010

I have an Aspire 7720z. As Vista was having so many glitches, I set up a dual boot system with XP and Ubuntu 8.10 on two partitions on the same drive. Last week I upgraded Ubuntu to 9.10 but started having power problems. I read somewhere that a BIOS update would help so I flashed to v1.45. Everything is now going great with my Ubuntu OS. The problem lies in Windows. When I try to boot to XP the splash screen comes up for a couple of seconds and the the computer reboots. I used a test disk to check the drive and everything is fine. I then tried to repair the XP installation with the install disk but was told that it couldn't find an XP installation. So, for the umteenth time, I tried to re-install XP but was told that the installer couldn't locate any devices to install onto. Completely bewildering as my Ubuntu installation works perfectly.

Acer Aspire 5517 :: How To Know If Need To Update BIOS

Sep 3, 2014

My Acer Aspire 5517 Laptop is running Windows 7 X 64 with an AMD Athlon TF-20 Processor at 1.6Ghz with 2GB of physical memory. Every once in a while, and lately quit frequently, my screen goes black, and it will not boot...I have attached an exterior Monitor to it, with no success, so I assume it is not the video portion. To get it to boot I turn it off and on until it re-boots. Sometimes it reboots quickly and at other times it takes several minutes...up to 20 or 30 sometimes. I have run a disc check to see if all the  sectors are good on the hard drive. It checks out okay..I thought if the BIOS was out of date, I would update it, to  see if that work....

Acer Aspire 5560g :: Failing To Boot After Firmware Update

Jan 28, 2015

So i recently upgraded my Aspire 5560g to Windows 8.1. I liked it but it seemed to have lost my drivers in the process (my track pad scrolling didnt work and my Dolby audio origram was gone).
I went to  for the drivers and decided to start with a firmware upgrade (9545 for hard disk performance). 
After the computer rebooted, I entered the dreaded Windows 8.1 boot loop. It would say "Your PC ran into problems..." with the bluescreen, then turn off. Then it would attempt the Automatic repair, and fail again, then restart the cycle.
I wasn't able to even get into my BIOS until I cleared my CMOS, now at least I can get into BIOS.
I created a bootable USB for Windows in hopes I could do a clean install, but even when trying to boot from a USB I get the blue Windows 8 screen, "Your PC ran into problems..."Is there a way I can undo the firmware update, it seems like the culprit, doesn't it? 
EDIT: I've read that the Windows boot loop may be caused by outdated drivers. Think this could be the problem after I did the firmware update? How can I install the drivers without being able to boot into Windows?

Acer :: Aspire 5100 Bios Update Failure

Sep 1, 2009

I have an Acer Aspire 5100
AMD Turion 64x2 Mobile Technology TL-56, 1.8 GHZ
Radeon Xpress 1100 hyperMemory
1 GB DDr2

It has vista home premium preinstalled. Lately I installed Xp on it (Ive done it many times before because its faster) The only thing is that with Xp it shutsdown after some time, 'cuase of the heat. So I thought I'll update the BIOS. It went well but then IT shutsdown! I was afraid of this but it happened. Now my Lap won't boot, nothing comes up, not even a sound! The only thing that work is the dvd driver. The fan goes like it would boot but nothing. I tried to flash it via usb but didn't read the usb.

Acer :: Aspire 5315 Failed BIOS Update

Nov 9, 2009

I attempted to update the BIOS in my Acer Aspire 5315 laptop to no avail, the winbios program froze straight away, while erasing the BIOS I think. So since then I havn't been able to start the laptop, no fans, but does blink a red LED beside the little light icon when left for longer than 10 seconds or so when you press the power button. I've tried the fn+esc method to boot it to flash the bios but nothing at all, tried it with USB and CD-ROM. I've tried removing all the hardware and starting it, I've also tried resetting the CMOS, still no luck.

I'm thinking that the red LED might be a little indicator of hope, or is it maybe the capacitor filling up

Acer Aspire V3-571G :: BIOS Update (Not For Upgrades)

Oct 9, 2014

I own an Aspire V3-571G Notebook with ArchLinux dual-booting Win8.1. When I'm starting Arch I get this (Ivybridge-/Sandybridge -related) error:

"[drm:cpt_serr_int_handler] *ERROR* PCH transcoder A FIFO underrun"

After research I think a BIOS Update should fix the problem. But in the BIOS-section there is a confusing line:
"BIOS - UEFI for Windows 8 (Not for Upgrades)"

So, does that mean:
a) not for those who had Win8/8.1 pre-installed (like me) or
b) not for those who have run an inplace upgrade of Win7 to Win8/8.1 instead of a clean install.

Acer Aspire E5-571 :: BIOS Update - Linux (Ubuntu)

Feb 4, 2015

I have an Aspire E5-571 without pre-installed OS. I don't care about Windows - I am using Linux (Ubuntu).

There are some problems reported by the Linux kernel at boot (UEFI mode) an I was hoping that a BIOS update may solve some of them (ACPI issues and unclaimed hardware). May be very well the Linux kernel but I can't exclude BIOS either.

On the Downloads page, under BIOS tab, there are four current BIOS versions with brief and strange description: versions 1.08, 1.09, 1.11 and 1.24

IF (and only if) I decide to update BIOS, which version should I use? What are the real differences between versions (Release Notes)? Except Windows 8 hacks, is there any real "improved system performance" on other OS? What is BIOS (5.2MB versions) vs. VBIOS (13MB update)?

Acer :: Aspire 4520 Dead BIOS Update Failure

Sep 1, 2008

Im using Acer Aspire 4520. Now my laptop have dead because im update the BIOS firmware on windows vista platform. On 8% progress its 'hang' now i'm can using my laptop.

the many solution i have try on this forum. not done.

FYI on my procedure

1- Run the Phoenix Crisis Disk -> Format the floppy procedure.
2- Open the Acer BIOS from website -> I get the Z03_3626.wph file then rename to bios.wph
3- Copy the bios.wph to Floppy drive
4- Insert the USB floppy to my laptop then remove the battery, hold the FN + ESC button, plug in power then press power button
5- I hear the floppy drive reading on 3minutes then after 3minutes the floopy drive stop and i release the holding FN + ESC button
6- waiting about 20 minutes nothing happen.

so what i want to do...? i think this is right procedure because it reading the floopy drive long about 3minutes. If i try burn the CD procedure nothing happen (can read), then try rename to .fd it not read.

Acer Aspire 5742z :: BIOS Update Black Screen

Feb 16, 2015

I've spent 3 days and countless hours trying to find the solution to a black screen after attempting to update my daughter's Acer Aspire 5742Z from the bios it had to the latest bios available on the site (1.30).  I ran the windows version from windows and I clicked thru the various dialogue windows appearing to be on its merry way.  At one point, the screen went black and after about a half hour it stayed that way so I unplugged it b/c it wasn't responding to the power button nor the ctrl-alt-delete. I've tried using a usb stick formatted to both fat and fat32 containing the dos version of the bios files and the full contents from a windows 98 startup floppy disk i dusted off from retirement.  I also tried a cdrw and cdr only containing the bios files.  In all attempts, the hdd led and either the optical drive or usb stick led blinked a little before dying out and nothing more.

Acer Aspire E1-571 :: Hangs On Boot Post Windows Update - Appears To Be Corrupt Driver

Feb 19, 2015

My daughter's Acer is 2.5 years old and it's running Windows 7.  She recently rebooted it last week for a Windows Update and since then it starts up but hangs, with the hard drive light blinking slowly.  I ran it in Safe Mode and it gets through CLASSPNP.SYS then hangs.  According to articles this is usually a hardware problem.  The only option I have with this OS is to bring up the Command Prompt.  I've tried System File Checker - no go.  System Repair comes back with unknown error and what looks like a bad Driver.
I was able to build a new partition (100+GB) and do a clean install of Windows 7 x64 Ultimate w/ SP1.  This went through fine, though I would have to load the Acer drivers for the network card, etc. to finalize it.  The point here is that this shows that the hard drive isn't the issue.
My fear is that Windows installed either some sort of driver or other update that has now caused the current OS on her laptop to be unusable.  I went to do a System Restore and the only restore point it had was the Critical Update that she rebooted to on 2/13.  Trying to roll back to that Restore Point didn't work.

Acer Aspire R7-571 :: Locks 3 Min After Boot With BIOS 2.09

Oct 28, 2014

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.

Lenovo P/Y/Z Series :: Z50-75 Won't Boot After BIOS Update

Sep 28, 2014

I just bought Z50-75 with AMD FX7500, 8GB Ram and FreeDOS. I installed Windows 8.1 Pro, and they pulled some drivers during the installation, and I went to Lenovo sight and downloaded all the rest (graphics, camera, etc.), after each installation the computer restarted normally and all was O.K. The last drivers that I saw on the site were BIOS drivers, and I downloaded those to and it started the installation after which it said:"The system will now restart for changes to make effect", and it did, but, it would not boot up after that, all it did was show me this on the screen:
And I tried both of the options (the second one with the Windows CD inside), but it just stays where it is, no effect.

I can enter the bios and change the settings, but none of them seem to work because this is the maximum where it will go, the only difference is when I change from AHCI to Compatible mode, it restarts and than I have a blank screen, I have to use the One button Recovery to get back to this one from the picture above...

Acer :: Boot Issue On Aspire 2930 Laptop Corrupted BIOS

May 9, 2010

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:


2. IDE1 :
3. USB FDD :
4. Network Boot :
5. USB HDD :

My friend's:
1. IDE0 : Hitachi HTS542525K9SA00
3. USB FDD :
4. Network Boot : Realtek Boot Agent
5. USB HDD :

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.

Acer :: Aspire Timeline 5810tz Won't Boot, Can't Access Setup Or Bios

May 7, 2010

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.

Acer Aspire 5810TZ :: Flashing BIOS - Boot It Up And It Just Showing Logo

Mar 13, 2013

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 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.

Acer Aspire M :: Boot Configuration File Being Invalid - Cannot Access BIOS

Dec 26, 2014

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.
