Acer :: Flashed Bios, Now Can't Power On Laptop
May 27, 2010
I was having issues with my laptop(keyboard stopped working, mouse jerky, trouble booting), and after a lot of research found that a common acer problem is that the bios is the wrong version, and that it needs to be upgraded. so i downloaded a bios upgrade off of the acer website and ran it.
now my computer will not boot up, pressing the power button does nothing, it doesn't even light up.
i'm assuming that it was a bad bios flash, and i'm wondering if there's anything i can do to fix it.
my computer is an acer aspire timeline 5810tz-4657, 320 gb ram, intel pentium processor, 3 gb ram. i had windows vista and ubuntu v 10.04 installed on it prior to the bios flash.

I have an Acer Travelmate 4070 series and have accidently flashed the BIOS. When I switch on now, there is a black screen and it seems that the laptop is a paperweight now.

I replaced the system board for an Acer Aspire 5552, and noticed that the product information for the machine, IE: Serial Number, SNID, etc are not flashed into the BIOS. The serial number for this is listed just as 123456789. Do any of you know how I can get my information flashed into the BIOS?

I thought it would be a good idea to flash the BIOS (latest version A24) before reinstalling Windows, but after doing that and installing Windows the on board mic isn't detected anymore! headphone jack, built-in speaker, work but the mic doesn't work. it worked right before doing the BIOS flash.
to remedy this I reset BIOS settings to Default, enabled and disabled Mic in BIOS settings, installed Dell Audio drivers instead of generic Windows drivers. nothing works.  in fact in BIOS diagnostic tests says Webcam/mic board not detected.

The charger is plugged in and the battery is at 100%. This is a M4500 Precision laptop with Windows 7. I tried flashing bios from safemode, also from Windows PE.

There are a lot of BIOS MOD request forums out there but most of them only specialize in SLIC modification. Our job is to unlock hidden menu in the BIOS. We don't want to use "specialize" word here but we know the "how" to get the job done. Based on the old thread Acer Laptop with Phoenix BIOS: Enable Virtualization, we decided to open new thread which specifically deals with BIOS MOD requests.
Other BIOS modder (bob12x, Darkening & others) and I will help you to unlock hidden menu(s) such as Intel Virtualization Menu and Intel Speedstep Technology.............

I'm having major trouble with my laptop (an Acer Aspire 3660) which is about 2 years old now. I don't know if there is a problem with the internal power socket or something else, but sometimes when it is plugged it just won't run off the mains or charge the battery. Sometimes I can get it to charge up, seemingly by rotating the power cord cable but at other times it will randomly go to battery even though absolutely nothing has moved, and sometimes it will go to battery power with the slightest little nudge. I don't think this could be related to the battery as the battery seems to work fine (although it does drain quickly I guess it's pretty old in laptop terms). Has anyone else had this problem or have any suggestions? I bought a new power cable (completely new including power pack and the plug end) but the problem still happens.

I own a Acer Aspire 8930g which I bought at the end of November 08.
Ive been having power problems, Id be playing a game or just browsing the web, and the machine just switches off.
Upon booting up again and logging into windows I notice the battery is completely flat, and is charging at 1%
The laptop is ALWAYS plugged in.
It seems to run down the battery if the computer is put into sleep mode, even though the power is plugged in, and also, I think, cant be 100% but seems to drain the battery even when fully shut down with the power plugged in.
Strrange problems and is really annoying as you would imagine if your in the middle of a good game or halfway through a good movie.

just got an Acer Extensa 5420-5687 laptop (used no warranty), added a new hdd and plugged in and I get nothing, the battery light does not light up, I swapped power supplies with my 5102wlmi and I still get nothing, no lights no nothing I have a feeling I know where this is going which might be the trash bin, but I thought I might ask if there is something I should be looking for. I have tried holding the power button without a battery and all that neat stuff. The battery charge light does not come on at all, its been plugged in for about an hour now and I get nothing.......

I have a Dell Latitude D800 that will not power on. When the power button is pushed the green power indicator light comes on, the CDROM spins for a moment, but then nothing happens, there is no BIOS information displayed, no power on self test, no Dell logo. It just sits there with the green power light on.I have tried removing the power & battery then pressing the power button for 10 seconds (actually, I have tried as long as 60 seconds). I have tried to turn on with the power connected but not the battery. I have tried removing the connector cable for the power button and the connector cable for the display and then reseating them.

I currently have a Acer Aspire V3 Laptop that runs on the most current version of Windows 8. Ran perfectly fine last night without any kind of problems. Went to get on it this morning and the power button won't respond. When it is plugged in, the LED light shows that it's charging, but when I try to turn it on, the power button doesn't respond. Every few presses, the power button lights up for a split second, then turns off. The screen never responds to the power button being on for a split second.

After replacing the fan, I have a power up issue with the laptop. Basically, the laptop will only power on with the power cable disconnected at the motherboard. It was by mistake that after the fan was replaced and everything was put back together, that I noticed that the battery was not charging.
Â
I then reopened the machine and reconnected the power cable to the motherboard and nothing - no power.
Â
When plugging in the power source with the battery in place, the LED adjacent to the power socket lights up WHITE then stays ORANGE and will not power up. No other lights, no fan noise, nothing.
Â
If I remove the battery, the LED adjacent to the power socket lights up WHITE and stays white however will not power up either. Same agin, no other LEDs, not fan noise, nothing.
Â
I have now opened the machine back up and disconnected the power from the motherboard. Put it all back together and the laptop powers up as normal with the battery and it works fine. (Well until the battery runs out anyway).

Our Studio 1749 will retain a solid connection when the power adapter is plugged into the power board along the side of my laptop. I am unsure if the pins residing in the power board are pushed toward each other so as to not retain connection when the adpater in plugged into the laptop.

I have just installed a fx2500 in my M90 and was wondering if I flash it with the Fx3500 bios would it become a fx3500? It seems from the specs that the only difference is the core/memory speed.

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.

Some specs:
7900gs, flashed to GTX. Idle at 55-60 C .
Dual monitor (one dell 19" LCD + laptop)
This setup worked OK for many months.
Today, this happened:
Wake from hibernation.
Browse homepage (internet)
Monitor blanks, mouse freezes
Laptop display blanks.
I turn off computer.
Here is status NOW:
I can boot in safe mode. I have cleaned old video driver.
Boot in regular mode. OK. (with video driver uninstalled)
Install ANY video driver (win XP, media center)- the display freezes, and blanks after the windows loading screen. I do not get to the log in page.
There are also strange lines all over the screen (during boot)
I need this computer for work, so I must fix asap. I would like to know if I should purchase a new video card.

1. Is their any unofficial, modded, or good BIOS for this laptop? I currently have 3508
2. Is their anyway to update the graphics card bios for this laptop?
3. Does this laptop support Bluetooth? I heard it did, and I heard it didn't.
4. Is there anyway I can control fan speed?
5. If I'm using the back USB ports of my laptop, and repeatedly plug and unlpug my speakers from the wall plug, my USB devices turn off for a quick second and come back. Is this normal?
6. On the front of my laptop, I have 3 audio jacks. I have no idea what the 3rd one does.
7. Is their anyway to use the € and $ keys on my laptop without Launch Manager?
8. I have 2 switches on the front of my laptop. 1 For Bluetooth and 1 for Wifi. So if I didn't have bluetooth, what would the bluetooth swich do even? (Related to question 2)

Since 2 years ago, I owned an Acer Aspire 9420. It is a 17" laptop with Intel CPU (Intel C2D T5600). According to Intel website, T5600 processor have Intel Virtualization Technology. However, for unknown reason, there is no option to turn ON Virtualization in the BIOS. Even Acer doesn't provide BIOS update that support this feature. My works involved VMware simulation & this prevent me from running 64 bit guest OS. Since buying another laptop seems not worth at all & Acer Aspire 9420 is a strong laptop to do heavy job, I'm determine, what ever it takes, I will enable Virtualization on this laptop.
For the past 2 years, I have working hard to achieve my objective. I has search & search in the internet and I found a couple of article about hacking the BIOS to enable Virtualization. This is a few forum's threads & articles I found:-

I've run into an issue that has stricken every single laptop, regardless of OS, that I've ran that has an intel 4965N WiFi card. Dell Latitudes, Inspirons, Acers, HPs, Lenovos, Toshibas, Gateway, Sony, XP, Vista, Server 2008, Windows 7, 32 bit, 64 bit.
Transfers of large files to my NAS, such as DVD ISOs, system images, or VMware images, will result in a failed transfer 100% of the time.
The issue does not occur with Broadcom or Atheros cards, or intel cards such as the the 2915ABG, 2200BG, 5100N, 5300N, 5350N. Just the 4965N.
I have an intel 5100N card I bought for a friend to use in a laptop, but he opted to use a Broadcom card that was supported in OSX. I'd like to use it in the HP to fix this issue, but unfortunately, HP's current whitelisting of WiFi cards prevents me from doing so. find a BIOS that will let me use my 5100N?

I have an Aspire 6930 that suddenly died and will not power on. The LED power button was dark and unresponsive. I performed a power reset and the blue light on the power button came back on until I pressed the button to try to restart the laptop. When I did that, the blue LED immediately went dark and stayed that way until I did another power reset. It never gets to the point of anything powering on. Is it a problem with the battery or it the laptop toast?
Â
This is a real bummer since I just replaced the hard drive a few weeks ago and replaced Windows Vista with Linux Mint (which btw is blazing fast compared to Vista).
