after fitting a new hdd to a Toshiba Satellite C660 laptop (model code PSC 0LE), I was installing Win7 64bit from scratch.
The OS had loaded, and I was installing drivers. After the motherboard driver install, it rebooted - a little faster than I was expecting - I thought I'd clicked the button to Reboot Later. However, after reboot, there is no screen display at all, no POST, no beeps, nothing. There is a single short flash of the power led on the laptop, and the cpu fan can be seen to spin up for a few seconds inside the casing.
It does the same thing now with the HDD removed, or with either or both sticks of RAM out. Connecting an external display shows nothing, either. The only difference is if the battery is removed (but power still attached), it won't boot at all.
The old HDD is definitely bad - not even seen in BIOS on other PCs, and sounds physically damaged. The laptop had been jolted to cause this fault in the first place.
My suspicion so far is that the Mobo update has damaged the BIOS. I've been trying to get a BIOS update to work, but most toshiba utilities seem to want an OS to be in place.
I've downloaded the update from here, and run it on another PC (but not to the end!)
As it runs, it unpacks the files to a temp location:
- in this location is the BIOS.ROM file. I've copied all the files out of here, and then cancelled the installation (as I don't want to flash a laptop BIOS onto my main PC!!). This BIOS.ROM file is 2100 kb - therefore too big for a floppy...
After seeing advice on other forums, I've been trying to make a bootable USB memory stick, and to use this to recover the BIOS.
[most of the download links there are dead, but the concepts seem to make sense]
To make a bootable USB disk, I've used http://www.bootdisk.com/pendrive.htm
- Method 1
I've tested this on another laptop, and it boots to FreeDOS nicely.
The instructions on using it for BIOS recovery are more complicated though - there are many online references to WINCRIS.EXE, which should make a bootable **floppy**, but the problem I have here is that I can't fit all the file onto the floppy.
I've also tried copying all the files to my bootable USB, and then the recovery process is supposed to be that you remove the power AND battery, connect power ONLY, and hold Fn + F while you hit the power button. Hold the keys down for 10 secs
- however, on doing this, I get no response at all, not even the single LED flash of before.
Other sites refer to other keys, notably Fn + B, Fn +F3, Fn + Esc - but none are working.
This is a friend's laptop, and he's really skint, so I don't want to end up with a large repair bill for a whole mobo replacement unless we really have to.
Anything else worth trying?
