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.

Dell Latitude E4300 :: When Bios Is Flashed Now Built-in Microphone Is Not Detected

Apr 11, 2013

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.

Acer :: Laptop With Phoenix BIOS: BIOS MOD Request

May 3, 2010

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

Acer :: Aspire Laptop Power

Oct 8, 2008

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.

Acer :: 8930g Power Laptop Is ALWAYS Plugged In

Jan 22, 2009

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.

Dell Latitude D800 :: Will Not Power On / No BIOS Information Displayed / No Power On Self Test

Apr 16, 2013

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.

Acer Aspire V3 :: Laptop Won't Start - Power Button Does Not Respond

Nov 9, 2014

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.

HP Pavilion G6-2148TX :: Laptop Will Only Power On With Power Cable Disconnected At Motherboard After Fan Replacement

Oct 21, 2014

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.
 
I then reopened the machine and reconnected the power cable to the motherboard and nothing - no power.
 
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.
 
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.
 
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).

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:

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.

Acer :: Laptop With Phoenix BIOS: Enable Virtualization (Test Machine: Aspire 9420)

Mar 8, 2010

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:-

HP/Compaq :: Either The BIOS Goes, Or The Laptop Goes Whitelist BIOS For An 8710W

Jan 30, 2010

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?

Acer Aspire 6930 :: Will Not Power Up Even After Power Reset

Oct 13, 2014

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?
 
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).
