Damaged Bios When I was upgrading the BIOS in my Satellite 1955-S807 the power went off resulting in the BIOS being damaged (apparently) I assume it was damaged because the instructions warned about making sure the power would not go off during the upgrade process. The laptop which was working beautifully for the last 3 years just died. A toshiba service repair center wanted to replaced the motherboard that costs more a new laptop. The question is: is there anyway to repair the damaged BIOS without having to replace parts, I understand it is a programming problem what I have not a hardware break as such. Thanks a lot

    Thanks for replying. I double checked the motherboard and in fact the chip is not removable, it comes soldered to the board. I believe I'm gonna have to let it go, rip it apart to use the memory and other usable parts and let it go, I was really satisfied with the laptop's performance but as you said that particular warning in small letters is just another way to mislead the consumer, due to the criticality of such upgrade it should not even be posted in the Toshiba's website. My advice for Toshiba owners!! Don't even try to upgrade the BIOS unless the computer is still under warranty. I lately found out that there wasn't a power outage in my area, it was just the laptop that turned itself off during the process. Let's just call it bad luck, so I don't make my day miserable. Thanks again

In older machines you just replaced the BIOS chip with one that had been programmed outside of the motherboard. Newer computers don't have that luxury as the BIOS is often burnt into a chip that is soldered to the motherboard. Too expensive to have chips mounted by humans at the factory. Also, increases the depth of the motherboard and in today's designs, creates additional problems. Your tech at the service center is correct. The warning should be a WARNING!!!

Laptop keyboard mouse not working


Toshiba has released a few different advisories related to its Satellite line of laptop computers having keyboard problems. Remember that damage caused by liquid or physical damage is not usually covered by warranty.

Bios Fixes
On Satellite models 1955-S801, 1955-S802, 1955-S803 and 1955-S804, the BIOS (system utility setup program) had trouble reading the firmware for the wireless keyboard. BIOS version 1.40 repaired this problem. The BIOS flash program can be downloaded from the Toshiba website. http://askiris.toshiba.com/ToshibaSupportSite/search.do?cmd=displayKC&docType=kc&externalId=286356xml&sliceId=&dialogID=124900040&stateId=0%200%2084585964 b> Satellite 1955 Text Anomaly b> Toshiba reported a strange, software-specific problem between the Satellite 1955-S801 and S803 computers and Microsoft Word and Excel. Users who held down the shift key for more than five seconds while using the arrow keys would see their highlighted text disappear. The only provided solution was to use an external keyboard attached with a PS/2 connection or to release the shift key if pausing while highlighting in those programs. General Troubleshooting for Satellite Keyboards b> For general concerns about the keyboard -- if it doesn't appear to be working -- try these few steps. Use the keyboard before Windows loads: hit F1 on the first screen that appears after turning the system on. If they keyboard works here, it's probably a Windows problem. Try attaching an external keyboard; if it works, the internal keyboard is likely broken.
Toshiba Laptop Mouse Problems
Some symptoms that occur with Toshiba laptop mice include jumping and vanishing pointers. These situations have occurred after software upgrades have been made. The problems can often be solved by following basic mouse troubleshooting methods. Overall, Toshiba laptop mice contain the basic functions characteristic of the USB variety.

Function b> The mouse device is used to move, open, delete and otherwise connect with items available on and through the computer monitor. In Toshiba laptops and many others, the mouse pad replaces the point and click USB mouse device. This enables the mobile computer laptop to be more compact, portable and ready to use. b> Features b> The mouse pad on a Toshiba laptop is located in the middle, directly below the keyboard. The control buttons, both primary and secondary are situated below it. The primary key, on the left, represents the left-click button on an USB mouse device. The secondary key on the right represents the right-click button on an USB mouse. This button is used to pull up the short menu of an item after selecting it. Update Keyboard Driver b> Many Toshiba mouse issues can be solved by updating the driver. The driver enables the mouse to function properly. Update the keyboard driver first to increase mouse and keyboard device compatibility. To complete this task, click "Administrative Tools," accessible from the Start menu. Next, click "Computer Management," and then select "Device Manager." Click the "Keyboards" expansion node to bring up the list of installed hardware, and then right-click on the keyboard that is in use. If the "Update Driver" option is available, click on it. Otherwise, select "Properties," go the "Driver" tab and press "Update Driver." Device Manager is a useful tool to update, rollback or uninstall incompatible drivers. b> Update the Mouse Driver b> Update the mouse driver by following most of the instructions in the above section, "Update Keyboard Driver." However, after selecting "Device Manager," click the expansion node next to "Mice and other pointing devices." Select the current mouse device in use and right-click on it. If the "Update Driver" option is available, click on it. Otherwise, select "Properties" and go to the Driver tab and press "Update Driver." b> Check BIOS Fixes b> Some older Toshiba laptop models require BIOS (Basic Input/Output System) fixes. Most of the downloads are available from their website. Since, the BIOS chip is the liaison between the hardware and software, any issues should be addressed promptly. Symptoms, such as erratic mouse behavior or the pointer disappearing, are signs of a need for a BIOS fix or driver update. b> Compatibility b> Toshiba and most Microsoft Windows products are compatible. This is vital when it comes to updating necessary drivers needed for continual operating system function. The service packs they approve of are listed on their website. Hope this helps.

Model Asus Eee 900A I tried to update bios and all of a sudden everything went off now no power at all, buttery is in good condition power charger is in good condition tried them on an other Eee and found...


I'm sorry but looks like the BIOS maybe damaged - you'll have to get the BIOS fixed or replaced (on the motherboard) unless it has a socket. If anything happened during the upgrade process like a power interruption, it could cause the problem. The BIOS upgrade process does an erase/write flash of firmware to its' memory. If disrupted, the firmware codes become corrupted.

How to upgrade BIOS in my XW400?


Upgrading the BIOS is an easy task but not recommended unless your computer has a problem which will be solved by a BIOS upgrade.

I assume that you are aware that a failed upgrade may render you system unusable till it is reloaded. Primary cause of a failed upgrade is a power failure so please make sure your PC has a back-up power source in case of a power failure.

The latest BIOS update can be downloaded from this website.

Download the exe file on your desktop and double click on run it. It is to be used on Win XP or 2000.

Before upgrading, check the version of your BIOS. If the version number is same as the one with you are upgrading, it means you have already the latest BIOS and it is not necessary to upgrade. The version number of this BIOS is 3.06 Revision A.

I have a toshiba satellite A205-S5809 and after a bios upgrade it will not power up. Can anyone help me?


A bios update should not cause the laptop to fail in powering up. Regardless, whether you used the correct bios update or not, the laptop should still power on. You may not be able to boot to windows, but you should still power up.

You are have hardware failure unrelated to bios change.

Bios damaged


Best thing to do courtesy of Toshiba is to try and update your BIOS by going to this page:

http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/modelContent.jsp?ct=DL&os=&category=&moid=1209157&rpn=PSAA0U&modelFilter=A100-S8111TD&selCategory=3&selFamily=1073768663&selModel=1209157|PSAA0U

The file you want to download is the one that says BIOS, it will be the 4th file down that you want. Download it and run it from windows, it will update your BIOS and may take a while. Once it tells you its complete, reboot the computer and try going into the BIOS then and see what happens. Should take care of the problem as long as the BIOS wasn't completely corrupted.

Toshiba Satellite M45-S169 CPU Upgrade


the chipset will support pentium M processors and some pentium 4 notebook processors. the bios should recognize the processor's new speed and should be able to support a 533mhz fsb. as long as your celeron is not soldered to the socket, you should be fine with the upgrade.

Can't change any settings in BIOS on Abit At7-MAX2 model KT400-8235


It is possible that the bios is damaged. You ran the flash utility correctly by what you posted. It would be worth it. Most companies chargh $5.00 us. Can't beat that.
