Toshiba Satellite L755-s5306
Anyway, after a lot of research and swapping parts I've pretty much came to the conclusion that she had a bad BIOS flash. Apparently this was somewhat of a big deal awhile back for the Satellites and a lot of people were having issues with it.
The symptoms are that the computer receives power and turns on while the screen stays black and unresponsive. No POST, no beeps, nothing. The fan continually speeds up and slows down. The first three indicator lights (AC plugged in, laptop powered up, and battery light) all three light up as normal. While the hard drive is in, its indicator light flashes as normal. However, nothing else happens. I've reseated and swapped RAM modules, I've disconnected all extra peripherals, I've pulled the CMOS battery, I've swapped the hard drive, I've pulled all power sources and held the power button for 30+ sec. The only thing that I haven't tried yet which I'm not even sure would help would be to reflow the GPU chip... regardless I've tried about everything else practical that I could think of.
So after trying to figure out how to blind flash the BIOS, the closest thing to help I could find online was http://forums.toshiba.com/t5/System.../dead-satellite-after-bios-update/td-p/103870 and http://forum.notebookreview.com/toshiba/469337-toshiba-satellite-a350-bios-recovery-phoenix.html which basically outline the same procedure.
I have yet to get this to work with a USB flash drive or a Micro SD card usb reader with the file systems formatted to FAT and the storage space being 2GB or less.
One thing that I'm not sure about with this laptop model is how exactly force it to boot from USB or floppy. I know some models are FN+B or FN+F or WIN+F or just U or whatever but I can't find any concrete advice on how exactly to do it on this model.
So with all the backstory, the questions I have that I hope some might have an answer for here or at least point me in the right direction is:
1. What is the correct key combination to force this particular laptop to boot from the USB when you can see the screen.
2. I've downloaded the latest BIOS update from the Toshiba website for this model, but all the instructions I've read say to look for a .rom or .wph file to rename. All I can find in the downloaded container files are .fd files which I'm not sure would work the same.
3. If all else fails, would an EEPROM programmer work to flash the correct BIOS?
4. I know I could just inform the customer they need to purchase a new motherboard, but I like the challenge and the customer is actually a friend of mine so the waiting part isn't of concern.
Thanks in advance for all your advice and help!

- 15.6-inch glossy 720p display (1366×768 resolution)

- DVD burner (TSSTcorp CDDVDW TS-L633F)
- 6-cell Li-ion battery (10.8V, 4200mAh, 48Wh)

- Price: $689.99
These specifications are almost lacking for a notebook priced at nearly $700. The included 640GB hard drive runs at a pokey 5400RPM and holds back overall performance. 4GB of RAM is the minimum these days; some similarly-priced notebooks offer 6GB. The 1366×768 screen resolution is the lowest offered in this screen size across the industry. The L755 just doesn’t have anything above the bare essentials.
Performance and Benchmarks
The L755 performed well in our benchmarks. Anyone looking for a casual computing device should not be disappointed with its performance. The L755 is not good for the latest 3D games as configured since it has an integrated Intel graphics card, not a powerful Nvidia GeForce or AMD Radeon dedicated card. It’s more than enough for everything else including HD video.
