I have a Compaq Presario 2175US Laptop, the other day I began installing updates from Compaq's website and without thinking I ran their windows based bios flash. The program made a backup of the bios and began to flash the new bios , as soon as it got to writing block 2 of 8 the laptop shutdown completely and only the wifi power and caps lock scroll lock and num lock lights were on .
This lasted 1 hour before I turned off the system because it was beginning to get hot . Now when I turn on the system the same situation happens. The wifi power and caps lock scroll lock and num lock lights come on the CD rom sounds as if it is reading for 2 seconds and the HDD sounds as if it spins up then stops. I have tried hooking up a usb floppy drive and holding FN+B and it will not read this drive or boot it at all for some reason .
Any help at all in recovering this bios is greatly appreciated . Thank you in advance .

I tried removing the cmos battery and it still produces the same result. I was told that I could use a boot block jumper but I'm unsure of how to make one and what matterials to use.

you'll better contact compaq for help, since a bad bios flash gives you just an expensive paperweight.

If you are not under warranty and if Compaq advices to change mobo...Don't accept that fast...Aim on repacling bios chip first...In the end, if you are very sure that bios chip won't help...then mobo...
