Re: bios flash

This is something that I really would not recommend doing unless you are sure what you are doing as this can seriously harm the computer. The best suggestion is to contact the sony help online and send them your product number and serial number then they know what flash bios you have and can send you a link to the correct download. Through experience when I tried to do a flash bios upgrade my computer went dead until I opened the back and had to shock the dumb thing.

Hello, My name is Keith and I run a small computer repair store in Alabama. I have a customer that has a Toshiba Satellite C75D-B7200 and he cannot remember the BIOS password

Hello Keith!

First of all, there is an OEM Toshiba software out there to flash the bios directly from windows, doing so will remove any password and restore the BIOS to it's original settings with an updated version. If that still doesn't work, consider a 3rd party software to recover the password or if the bios is socketed and none of the above solutions worked, order a new one directly from Toshiba.

Be ABSOLUTELY SURE to flash the BIOS with the correct version according to the model number of the laptop and that you connect the laptop with the power adaptor so it does not run out of battery in the middle of the process failing to do so might rend the computer unusable with a corrupted BIOS file.

Combination for flashing BIOS

You will have to purchase an eeprom that is pre loaded with the correct bios to replace the bad bios eeprom. You will need a hot air desoldering machine and lots of expertise. Flashing the bios when there is an anti virus programme on your laptop can cause issues. The anti virus programme will not allow writing to the eeprom and leaves it empty. So the processor has no boot programme to run and won't do anything at all, not even run to bios.

How can I recover my

Flashing a motherboard's BIOS can have many positive purposes and can help keep a motherboard compatible with changing technology. says that a proper BIOS flash can introduce enhanced features and bug fixes for the motherboard.

However, a bad BIOS flash can be devastating to a computer owner and very difficult to recover from.

If the proper preparations are made and all instructions are followed, a bad BIOS flash can be corrected.

Remove the side panel of the computer case, using the screwdriver to unfasten the screws normally located in the back.

Remove the jumper from its normal position on the motherboard and place it in the recovery position.

Usually, the jumper will need to be moved over one space to cover a previously exposed prong.

Locate the BIOS CMOS jumper on the motherboard, usually in the bottom, right corner.

The jumper consists of three metal pins facing upward and is usually marked with "CLR_CMOS" and has a plastic cap over two of the pins.

Check your specific motherboard manual if you are unsure where the jumper is.

If the motherboard does not have a jumper, removing the battery for 30 seconds and then replacing it may have the same effect.

Insert the BIOS flash disk and power on the computer.

If you used a flash tool or utility and did not create a BIOS flash disk before flashing the BIOS, then you will need to do so using a functioning computer.

Since there will be no video, listen for the internal PC speaker to beep.

This means it is performing the BIOS upgrade.

Power down the computer once the BIOS upgrade has been completed.

This process may take some time to complete, so be sure to not turn the computer off before the BIOS upgrade is finished.

Without video, the only way to be sure is to listen to the PC speaker.

When the upgrade is done, the PC speaker will beep again, and the floppy disk drive will turn off.

Replace the jumper back in its normal position and put the side panel of the computer back on.

Power the computer on.

If the computer turns on as normal, the recovery was a success.


How to Recover My Laptop BIOS

The BIOS is the basic input/output system on your computer that normally runs invisibly in the background, yet it's required for your computer to perform even the simplest task.

When something goes wrong with the BIOS, you might have difficulty even booting your computer.

There are a number of things you can do to recover a laptop BIOS that has gone wrong, ranging from relatively simple to somewhat costly.

Recover your BIOS by restoring the manufacturer settings as the first line of defense.

Reboot your laptop, reading the on-screen startup messages to determine what key you have to press on to enter the BIOS (normally "Esc" or "F2").

Press on the key when required to avoid booting into the main operating system, going instead to the BIOS screen.

Locate the item named "restore default settings" or "restore manufacturer settings"

(or something along those lines) within the BIOS.

Select this option using the arrow keys and pressing on enter, confirming when requested by pressing on the "Y" key.

This restores all of your old BIOS settings, potentially recovering your laptop BIOS with a minimum of fuss.

Send your computer back to the manufacturer or to an authorized dealer if restoring the factory default settings doesn't work.

The technician removes the old, faulty BIOS chip, replacing it with a new chip if possible.

It may also be a problem with the battery connected to the BIOS, which is always removable.

In many cases if the BIOS itself is the problem, the entire motherboard must be replaced since the BIOS chip is rarely removable in a laptop.

Hope this helps

L350-170, Updated bios driver,note book shutdown, now won,t start up. no screen nothing. any resolution to fix this?

Sounds like your BIOS update didn't Flash correctly. They usually give warnings at a website about the dangers\risks of updating your BIOS. Usually if the BIOS update didn't go well, then your computer, or the motherboard at least, is just a paper weight. Do you get any lights to light-up at all when pressing the power button. If so, then you have a chance of re-flashing your BIOS and maybe it will do it correctly the second time.

Emachines notebook m5310 corrupted bios recovery

Solution 1: Boot-block BIOS
Modern motherboards have a boot-block BIOS. This is small area of the BIOS that doesn't get overwritten when you flash a BIOS. The boot-block BIOS only has support for the floppy drive. If you have a PCI video card you won't see anything on the screen because the boot-block BIOS only supports an ISA videocard.
Award: The boot-block BIOS will execute an AUTOEXEC.BAT file on a bootable diskette. Copy an Award flasher & the correct BIOS *.bin file on the floppy and execute it automaticly by putting awdflash *.bin in the AUTOEXEC.BAT file.
AMI: The AMI boot-block BIOS will look for a AMIBOOT.ROM file on a diskette. Copy and rename the correct BIOS file on the floppy and power up the PC. The floppy doesn't need to be bootable. You will see the PC read the floppy, after about 4 minutes you will hear 4 beeps, this means the transfer is done. Reboot the PC and modify the CMOS for your configuration.
Solution 2: Get a new BIOS chip
Contact your motherboard manufacturer to see if they sell BIOS chips. Some motherboard manufacturers send them for free.
Contact a company that sells pre-flashed chips, like Unicore Software, FlashBIOS.ORG, BadFlash or BiosWorld
Solution 3: Hot-swapping
Note: I'm not responsible for any damage this method may do to you or your computer !
Replace the corrupt chip by a working one. The best option is to take the working BIOS chip from a motherboard which has the same chipset although that's not absolutely necessary. It just has to give you a chance of booting into DOS. Before pulling the working BIOS chip out of it's original motherboard, set the System BIOS cacheable option in the BIOS to enabled.
After you have put the working BIOS in the motherboard with the corrupt BIOS boot the system to DOS (with a floppy or HD).
Now replace (while the computer is powered on) the working BIOS chip with the corrupt one.
Flash an appropriate BIOS to the corrupt BIOS and reboot.
Note: Use a flasher from MRBIOS. They are known to work best. You can find them at
Solution 4: (for Intel motherboards)
Change Flash Recovery jumper to the recovery mode position (not all products have this feature)
Install the bootable upgrade diskette into drive A:
Reboot the system
Because of the small amount of code available in the non-erasable boot block area, no video is available to direct the procedure. The procedure can be monitored by listening to the speaker and looking at the floppy drive LED. When the system beeps and the floppy drive LED is lit, the system is copying the recovery code into the FLASH device. As soon as the drive LED goes off, the recovery is complete.
Turn the system off
Change the Flash Recovery jumper back to the default position
Leave the upgrade floppy in drive A: and turn the system on
Continue with the original upgrade

I flashed new bios on my CELSIH230, and now the computer is dead.

The new bios you flashed is either not compatible with your system or has been incompletely flashed, you need to restore the correct bios for the system, for this you would require a floppy drive, the bios is divided into two regions static and volatile, routines in the static region cannot be changed and supports booting from legacy devices like floppy drive. you need to copy the bios files into the floppy and use this floppy to restore the bios, I have tried this on desktops 4-5 years ago, For this you need to power-on the system with holding some specific keys (the keys differ from system to system)

How to flash my BIOS

Flashing Your BIOS

General Instructions:
Flashing [aka upgrading] your bios should be the last resort to solve a problem. Most people flash to gain the use of larger hard drives although recently, many are flashing to get all the features of XP to work. Other people have to upgrade their bios just to get XP to work properly with some specific hardware.

A couple of items are really important if you decide to flash. First. Make sure the updated bios addresses the issue you are trying to solve. eg many motherboard makers update their bios's for many different reasons. A reason may simply be to get a certain big name brand of pc to work correctly with a new cd writer big brand pc is selling.

So you really have to read the docs so see if the upgrade addresses your specific niggle or concern. Secondly, try your motherboard maker first to see if they have the files you need. Bios's upgrades are best had, if available, from the company that made your motherboard or pc. In most cases these are free.

Thirdly, READ THE DOCS CAREFULLY AND FOLLOW THEM TO THE LETTER. Dont skip any steps, especially the backup option if available. Fourth, if the upgrade calls for a clean bootdisk, use one. The disk I made especially for bios flashing is the one you can download above. It's a DrDOS bootdisk with NO drivers loading up in config.sys or autoexec.bat which is very important. My bios flash bootdisk is recommended by the most popular motherboad makers.

If you dont have a 1.44 drive I also created a utility to use to flash from a CD which you can add the new bios and flash utility to and then burn it.

It should have room to add your new bios, the flash utility, and also have room for the backup. If not one can always use another disk for the info. Always use BRAND NEW MEDIA when dealing with flashes.

In order to locate the correct bios upgrade for your motherboard you need to know who made it AND you need to know the model number. If your PC was made locally perhaps you have the manual. If not, then you need to find out the maker and model. Or, and very common with major brands, your computer maker will/may have the updated bios's on their website.

I have one windows and three dos utils that find your motherboard maker and model number. One of them should work for you. The DOS utils are on my DOStools Page under Diagnostics, and are called CTbios, MBID, and HW iNFO. The windows utility is called BIOS Agent and is on my Utilities Page under Hardware .

Once you ID your motherboard and model go the the manufacturers website and see what they have available. Note that some upgrades will come with their own bootdisk/utility so you may not need the disk I made.

Again, note that even tho many people flash their bios regularly to get the latest features and never have a problem, I still recommend it as a last resort as a flash gone bad will make your pc unusable if the backup doesn't work. Look at it this way, suppose I have a used 80 gig drive I want to resuse and my old P400 cant even detect it so I have an unusable pc. This is the best, and most common reason to flash.

On the other hand, if you have a more modern pc that cant see lets say a 180 gig drive and but all else is working properly then you may want to consider a PCI hard drive controller card which has an onboard bios that will see your new large hard drive and also come with 2 more IDE channels you can use in addition to the 2 channels you already have. This is safer than flashing the bios.

Acer aspire one model zg5 battery won't charge

I have exactly the same problem and am searching at the same time as you. I think you are wrong. I think the 150 is for the larger screen model. I think we need the 110.

I think it's this one that i found at acer-euro

but I'm afraid to use it (which is not to say I know how). Somthing about putting it onto a USB drive and running scripts. At least that's what they do with this problem on a 150

Acer Aspire 1800 not booting!

Did you make a backup of your original BIOS before flashing? If not you'll need to download the BIOS and reflash again. If you did then put your original BIOS back on the chip. This is definitely a BIOS problem. Worst case is you may have to purchase the BIOS from Acer or I've seen some 3rd party BIOS providers. I did not find the BIOS for the model you specified at the Acer site but I did find it at an English site: It's L12 about $15.00? Good Luck
