BIOS Chip Repair and Replacment
BIOS chip repair and replacement service for Desktop and Laptop Computers and other equipment that use flash memory.
BIOS replacement is often necessary after a failed or bad flash, and is a cheaper alternative to replacing the mainboard, which can be expensive. In most cases useable BIOS or ROM/BIN files are available from the mainboard makers.
We have a lot of mainboard BIOS Chips Available from the Programmed section of the website, with more being added on a daily basis.
Repairing the BIOS is simply a matter of replacing the damaged or missing code stored within the EEPROM or flash BIOS chip. Although uncommon, the BIOS chips or CMOS chips can develop errors and may just need to be replaced.
Soldered BIOS Repair
Most Modern Desktop Mainboards, and Laptops are now using SPI Serial flash EEPROM in preference to the PLCC Types and TSOP types previously used.
Most modern Desktops Mainboards now use removeable PDIP SPI Serial Flash PDIP EEPROM, some even have ZIFF Sockets fitted for SOIC Type BIOS Chips..
Modern Laptops in comparison are mainly using soldered SOIC SPI Serial Flash parts, rather than PDIP SPI Flash or Socketed SOIC parts. Older Laptops and Desktops would use PLCC, TSOP or VSOP EEPROM Types.
If you do not want to do the work yourself, we offer a soldered bios repair service, you will need to read the terms and conditions on the page before using the service.
Soldered PLCC BIOS Chips
If you are handy with a soldering iron and want to attempt to remove and replace a soldered PLCC BIOS chip yourself, then check out this page DIY soldered BIOS Repair it may save you a few headaches. This proceedure is not recomended for any other type of part ONLY PLCC 32 and should be a last resort.
We would normaly where possible use a hot air station to remove these parts and this would be recomended
Password Issues
If you need to remove a password then try this page Passwords and Security. we do not specialise in password removal and other than the limited information we have, we can offer no more advice
CMOS Battery
Some machines will not boot at all if these button cell batteries are at a low voltage. CMOS Battery Voltage should be between 3.0 volts and 3.3 volts, if it drops below 2.8 then the battery will soon need to be replaced.
Problem Motherboards
In the unlikely event that a new BIOS doesn't resolve your problem's, then your motherboard or other hardware may be faulty. If the file used to program the chip is the correct one and you still have a problem with a board then the board and or other vital hardware has to be suspect. It pays to remove any unnecessary hardware when trying to recover from a no boot situation.
It is important that you know your board has had a bad flash before you use this service, and that you know the model and revision number of your motherboard and BIOS chip part number. I will need this information to properly program a chip for you.
If you just suspect the BIOS to be the reason for no graphic's or no boot, then using this service is merely speculation and the outcome may not be favourable as the problem could lie elsewhere.
