Flashing the bios is NOT a fix-all !
It's the riskiest thing you can do with a computer !
Never flash your bios when you're not sure whether your computer, or your hard drive and operating system if you're flashing in Windows, is working properly !
Never flash your bios unless you MUST !
The only legitimate reason to flash the bios in most cases is to add support for recognizing a type of cpu that you want to install in the future that your present bios version can't recognize, unless you find specific info in release notes for a bios version newer than your mboard has that it will fix a problem you're having !
When you have the choice of either flashing the bios by using a bootable disk, or by using a flash utility built into the bios, or by using a flash utility in Windows, you should always do it by one of the first two methods, preferably the first one, because things are more likely to go wrong when you do it in Windows.
Even if you use the right bios update and the right flash utility, bios flash chips can only be flashed a small number of times, and the flash chip can physically fail when you attempt to flash the bios, sometimes the FIRST time you try.
You probably no choice except to hold the power button down until the computer shuts off the mboard, then press it again to see what happens.
If you see a "Cmos Checksum Error...." or similar message, and you DO NOT also see "BOOT BLOCK BIOS" or similar on the screen, the flash was successful.
Go into the bios Setup, set the current Date and Time, load Bios Defaults, Save bios settings.
If you DO see a message "BOOT BLOCK BIOS" or similar on the screen, the flash failed, the flash chip has probably not physically failed, and the fail safe Boot Block portion of the bios code is still there - in that case you can do a specific procedure to attempt to flash the bios again.
If you see no message......
- if the laptop has a built in floppy drive, if the led for it comes on while booting like it usually does when there's no disk in it, goes off, then comes on again for a longer time, you can probably do a specific procedure to attempt to flash the bios again, despite the fact you see no video.
