Hello.
I updated my mobile HD4670 with 2-3 different BIOSes trying to change the clock values and the device ID.
Updates were done by booting from a USB stick and running ATIflash in DOS mode.
The drivers were installed in Win7 x64 but couldn't start so I kept reverting back to the original BIOS.
In my last try, the system powered up, the disk tried to start up and couldn't, while the monitor stayed dark.
No lights on the USB stick either so I guess the system died early on.
The original BIOS run the boot at 625/500 (GPU and RAM, respectively) at 1.2 volts.
My last update had it at 700/500 at 1.25 volts (I actually forgot to put it down to 1.2).
1.25 volts was in the voltage table of the original BIOS but not used.
I suppose it's a power problem because of the modified parameters.
Does it sound like a valid assumption? It seems too small of a difference to cause this.
In any case, I removed a memory stick and tried to remove the two internal hard disks so I can use the USB stick only.
I managed to remove one of the disks but the system still wouldn't boot.
With the second disk I still have a problem.
Two of its screws are worn out and I can't find a way to remove them and pull the disk enclosure out.
Are there any tools for this that I can buy?
Anything else I can try?
Thanks for any help.
