HI, I have a R52 type 1848. I flashed the bios with a flash for type 1858 and during the flash, a message display : "Insert a recovery crisis diskette". When I have rebooted, the laptop makes 1 long beep and 2 shorts beeps (Maybe it's the graphic card) and I have a black screen. I made this diskette but it's not possible to boot whith the floppy usb.
Moreover, there is a fuse wire of the power AC that is blown.
Victor, please can you help me ? Can you send me a picture of the bios chip ? Can I reprogram the bios chip ? How can I replace the fuse wire ?

Thank you for your reply. Sorry for my english.

Best regards.

Sorry for the delay.
Yes, we can repair the BIOS binary code but you have to remove it from the motherboard and read it in a programmer. It is a SST parallel flash 40 pin.

The fuse must be replaced with another one exactly the same value, not just soldering a wire there.
