Nov 21, 2014

Model:  Inspiron 17R Special Edition Inspiron 17R Notebook (Inspiron 7720), Windows 8, 64-bit,English

My laptop was installing updates (not sure which updates) when the battery suddenly died. I charged it and ever since every time I turn it on, it gives me an error message and I'm unable to log into my system

error message is: BAD_SYS-CONF_INFO

I've tried accessing the BIOS with F2 button upon start up many times to check the settings but no luck. Pressing F2 constantly right  when the Dell logo appears does absolutely nothing. get back into Windows without reinstalling and losing everything

Dell Inspiron 1750 :: LCD Test Failed - Unable To Access EDID EEPROM

Jan 29, 2012

I have a dell inspiron 1750, and the past couple of weeks, i have been having intermittent screen problems, it occurs when i shut the computer down and then restart it, sometimes it works, sometimes i get a bit of light off the screen but its just blank (black), i know everything works because when the windows 7 start up screen comes on, i can hear the sound and can enter my password (even though i have a blank/black screen), i did a diagnostic test and the lcd test failed, i got the error code:

Error code 0321
Msg: Error code 2000-0321
Msg: LCD EDID - Unable to access the EDID EEPROM

I just moved he screen, and it goes different colours and pixels go out of place, i think it might be a loose/bad connection on the right hinge where the laptop joins the screen?

Dell Inspiron 17R :: Cannot Access BIOS Or Boot Order During POST

Jan 3, 2013

What I Was Doing:

All I wanted to do was install an SSD (SanDisk Extreme 240GB) as my primary drive using factory recovery created from Dell Backup and Recovery/Recovery Media from USB drive.... I was trying to update firmware on the SSD. It requires a download and the creation of a thumb drive to which one boots after adding it in the BIOS. Ever since I tried using that thumb drive during boot (on power up it was in a USB slot with the intention of opening BIOS and setting that thumb drive as a boot device to complete firmware update) things have been a mess.

The Problems:

I have run into a situation where no matter what key I press during startup, it has no impact on the startup. Main problem is that F2 will not open BIOS. F12 does not show Boot Order.

 Here are the symptoms:

Cannot access BIOS or Boot Order during POST All partitions on the factory 1TB hard drive now show in Windows File Explorer whereas previously only the partition labeled C: OS was shown

Potentially Stupid Things I Tried:

I discovered that if there are no hard drives installed, the system will boot to a DOS-type screen with options for Boot Order (with no drives it lists only Network Boot), Setup, Diagnostics, and Boot Configuration.

Setup takes me to the BIOS (vA11) but obviously with no drives showing Diagnostics takes to me to a test suite which when run gives me an error on the video memory but all else tests OK (tests of the video memory from within the Dell Suite within Win 8 show no errors) Boot Configuration gives me Legacy, UEFI Secure and UEFI Not Secure

I also downgraded the BIOS from A11 to A08 and then back to A11 in hopes of getting back access to BIOS but no luck.

Dell Inspiron 1564 :: Unable To Upgrade BIOS SW

The SW on my bios is A06. I downloaded the A13 ( the windows executable ) and ran it as admin. A windows poped up warning that the pc would reboot after completion. I click on Flash, a CLI poped up, done a few things and showed a success message. But when I go into the BIOS, it's still ver A06. By the way my os is Win 7 x64 ....

Dell 17R SE 7720 :: BIOS Will Not Allow Access Unless HDD Pulled

Jan 20, 2013

I have been having numerous problems with the BIOS where it will not allow boot device additions, required two power-ups to boot W8,  and finally today I can not even get into the BIOS A12 (latest)  with F2 or F12. Pushing F2 and F12 was completely ignored by the BIOS as it would only boot W8, even though it worked fine until yesterday.  I finally had to pull the hard drive to get the BIOS to give up and let me in. 

Seems to have a mind of its own but it did present the BIOS menu.  I had no problem using F2 & F12 on BIOS versions A10, A11, A12 before today except A12  did delete all the boot device priorities when initially loaded a week ago. That glitch caused the two power-ups everyone is starting to see.  The two power-ups are gone now but I need access occasionally for DVD's. Seems like there is some type of adaptive "smart" (I call it "dumb") strategy in the BIOS that really confuses us users to the point where I  am wasting way too much time chasing phantoms.

 The really big problem is that there are zero (none) Manuals with this computer.  The maintenance disassembly manuals are even gone.  No one has any write-up of how the BIOS is supposed to operate?  Dell explain how this BIOS is to be used to add boot devices?  Pulling HDD's is not the answer for most users as we are just going to wear out the HDD electrical bus connector when you want to boot a legacy MBR ( or an .ISO) DVD.

If you already have BIOS A10 installed. Version A10 was the last unlocked BIOS while  A11 and A12 are locked right up and very unpredictable in behaviour. Deleting A10 and the maintenance manuals from the download site is pretty  vicious on Dells part in my mind.  The maintenance manuals were called "Owners"  or "User" Manuals of which the obvious intent was to cover up there are no real owners manual to explain the basics like the Function Keys to get into the BIOS and use it.

Acer :: 5536- Bios Access

A friend with a desktop PC discovered that by some weird key combination before boot, he could get into further bios screens and set timeouts for disk access etc.

I'm trying to find a way to switch off the Realtek device at the bios level on my AS 5536, with Phoenix bios. Is this possible?

Lenovo Z50 P/Y/Z Series :: Cannot Access BIOS

Jan 14, 2015

I have searched the issue and all I can see is I have to flash the bios. I am not comfortable doing that because I have done this before on my Alienware and it took me three days to restart the computer. Everything was messed up.
 
All I want to be able to do is charge USB devices when the computer is in sleep mode. I have set Windows 8 power mode up, but it appears the BIOS is still preventing this from happening. So I need to access the BIOS.When the computer restarts no message appears to say *'hit F2 to enter BIOS'.So I have tried, Fn + F2, Fn + F1, F1, F2 and none enter the bios on start up. How do I enter bios on this Z50?

Acer Aspire M :: Cannot Access BIOS

Jan 3, 2015

I'm a high school junior with a year+ old Acer computer that has broken down twice and is now out of warranty.  I purchased this computer with my own money.
 
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 offeres 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.

Lenovo Yoga 2 Flex :: How To Access BIOS

Jun 21, 2014

I purchased a new Flex 2-15 online the past week. The model name shown on the back is "20405". Manufacture date is May 12, 2014. The User Guide refers to a "Novo Button", which is shown in diagrams as being on both the left edge and the right edge near the front. Neither location has a button of any sort. The right edge has a pinhole in the supposed button location. A curved arrow icon is next to the pinhole. I have an inkling this may be some sort of factory reset button. Lacking the Novo button, what is the procedure for accessing the features which the manual says are accessed by pressing this non-existent button?. That is, BIOS, and/or the one touch image backup/restore system?

Lenovo P/Y/Z Series :: Y410p Can't Access Bios

Feb 16, 2014

I was trying to access my BIOS recently, but whenever I attempt to do so, all I get is a constant beep sound. I used to be able to access the BIOS just fine, but now I can't. The computer itself still boots fine, though I also can't select any boot options either.
 
I thought I could fix this by resetting the BIOS, but there doesn't appear to be any way of doing that. The CMOS battery is nowhere to be found, and there is no BIOS update for the Y510p that I can apply.
 
I can get back into the BIOS?

Acer Aspire V5 571G :: No Access To BIOS

Nov 29, 2013

I can´t enter BIOS on my notebook, I don´t know what´s the problem what to do now.
 
What did I do? I had Windows 7 installed and everything worked well. Then I decided to install Debian GNU/Linux instead. That worked as well, though I had some issues with wifi connection and the system did not shutdown properly. That´s why I wanted to reinstall Windows. In order to boot from DVD, i had to change the boot order, because Debian always changes its own boot priority to max - so at this point BIOS was still working! During Windows 7 setup, I formated all HDD partitions, created new ones and BAM! Windows 7 would not installt because it has some problems with GPT partitions, it said it could not install to this partition (I tried all). So I canceled the installation and restartet the system. Of course now it printed "Operating system not found". I could not even enter  BIOS (allthough it showed the normal message "Press F2 ..." and the Windows 7 installation had trouble finding some drivers, so it did not even start correctly. The Acer Recovery I created from Windows 7 (before installing Debian) started, but it failed to copy the first file and ended. So nothing worked. However, I could install Debian again, which is now my OS.
 
Current situation: OS is Debian 7, it´s working, but I have many problems with it (cannot change display brightness, often looses wifi connection, instantly reboots (!) after shutdown) Can´t enter BIOS: I have tried F2, DEL, ESC, F10, F12 without success. Debian is again at boot priority #1, and I can´t change it without BIOS (so not able to BOOT from DVD etc) I have tried to short the G2201 contact (service manual describes how to use it to remove BIOS password), no success. Maybe it´s import that I use GRUB bootloader, which was automatically installed with Debian...

Lenovo T400 / T500 :: Won't Boot (can't Access BIOS)

Nov 9, 2009

I have a T400 2765-P3U model, and it won't boot up.  When you turn it on, you see the Thinkvantage logo and it stays there.  Trying to access the BIOS is non-responsive.  I connected the hard drive to see if it was a hard drive issue, but it's not.  The hard drive is response when connected via USB.  I can't get past the Thinkvantage logo, no response when attempting to access the BIOS.  It's still under warranty, so I'll probably send it in for repair but thought I'd give it a try fixing it before hand.

Lenovo U/S Series :: U310 - No Longer Access Bios

Oct 20, 2012

I bought a u310 slightly used but had a failing HDD. The person who was using it installed an operating system on the SSD and now I can't seem to access the bios at all. I had read that this may happen if Rapid Start is not disabled before formatting the SSD. 
 
What do I need to do to be able to access the bios again? There is no bios files listed as a download for this computer so I can't even seem to be able to flash the bios.
 
I already sent it to lenovo to replace the HDD and instead they tried to charge me $167 to image the machine, which I said no to and they sent the computer back without fixing it.

Lenovo 11e E/Edge :: Cannot Access Uefi Bios Anymore On E535

Sep 23, 2012

I recently bought a new E535 laptop working like a charm up to now. Bios access was possible by pressing Enter directly after switching machine one, than came some sort of POST analysis which could be skipped by pressing any key and than came some sort of table where I could access Bios by pressing some key (cannot remember which it was exactly). Alternatively I could enter Bios when in boot menu by pressing tab which switched to another tab where Bios could be entered (also some sort of diagnosis programs could be started). As mentioned in the subject it is impossible for me to do this now, after I did the following:
 
- exchanged built in HDD with an new SSD (Bios access yet possible)
- changed in Bios Setup boot mode from both (legacy + UEFI) to Uefi only (this might be the problematic point but I'm not sure)
- Installed Windows 7 in Uefi mode on ssd
 
No when I press enter on startup it brings me to Windows boot manager menu (you know where you can say start Windows normally or in safe mode and so). Boot menu also changed with a new "start windows" entry (well, this seems to be correct), but when switching to the other tab it is empty now, no entry for Bios setup or diagnosis tests anymore.
 
This is really bad. I have googled around and tried the following up to now without success:
 
- Pressing F1 instead of enter
- Shutdown laptop, and start with F1 pressed down
- starting without HDD
- starting unmodified HDD which was originally installed in laptop (which cannot be booted anymore, probably because it was installed in legacy mode)
 
I have also thought about flashing the bios, but the newest version available on lenovo support seems to be 1.04, but pre installed on my laptop is 1.10, so my version is a lot newer. Should I try to flash it nevertheless ?

How can I access the BIOS on the ACER 4755g?
 
I have tried mashing f2 a million times, but no luck.  f12, f8, ...none of these get me into the BIOS.

The BSOD is a 7b meaning some disk issue...tried all troubleshooting like unplugging all peripherals, removing RAM 1 board at a time, swapping RAM position....etc.

Lenovo ThinkPad L R/SL :: R400 Freeze On Boot Before BIOS Access

Feb 10, 2013

My R400 laptop (7447-W14) suddenly freezes on boot: it displays the early logo ("thinkpad, to interrupt normal startup, press the blue Thinkvantage button"), and waits forever, neither the bios menu nor the operating system (windows and ubuntu in dual boot) appears.
 
I can shutdown by holding the power button more than 5s, but on reboot, the same freeze come back, whatever I do:
- holding the F1 key before and after powering on
- holding the "ThinkVantage" button
- doing this on battery, or with power supply (with or without battery)
- trying to boot on an external USB HD drive
 
It does not seem to be a CPU problem (nothing would be displayed), nor RAM or harddisk one (it is cheked later, at BIOS time).
 
In fact, I was wondering wether removing and putting back the small battery of the mainboard would solve this problem ... but this battery seems not to be eaysyly found. At least, it is not under the keyboard, where the RAM is.
 
of course, warranty has ended ... any way, before I throw this laptop to trash ?

HP Pavilion G7 OS/Software :: Can't Access Bios Settings / Disable F1-f12 Keys

Jun 27, 2014

I got this Notebook-PC in 2012 it is a G7 series I am fairly sure. My problem is that when I turn off the computer and turn it back on, there is no (esc) option to open bios menu or any option for that matter. Just a blue HP symble directly in the middle of the screen with a small loading symbol below it. I have pressed esc, f1-f10, and pretty much every other key to try to access it. All I really want to do is disable the most annoying f1-f12 function keys.

I am no longer under warranty and my operating system is Windows 8.  There are also no error messages at all, just no response to anything just loads up to the password login screen.

Lenovo B / G Series :: G500s Hung At Startup And Can't Access BIOS

Sep 11, 2014

I have a problem with my Lenovo G500s  1.1 years (1 year & 1 month). It worked perfectly until last month. It started to freeze. I restarted the computer (btw I was using licenced win8 back then) and then the lenovo logo showed up and it stuck there. I was waiting for about 10 minutes, but nothing happened. I turned it off manually, and then turned it on,it was still frozen. after some trial of startup,  it worked normally. After 2 days it happened again. I thought it was the system, so I deleted the windows8 and installed windows8.1 licensed, it worked for a month and then again (last night) it just freezes at startup (lenovo logo shows up). Till now its frozen. I restarted it several times, it didnt work. I also pulled out battery & started on AC power which didnt work too. Obviously, i dont have warranty.

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.
