Bios Boot Recover .fd or .bin code for Predator 17 g9-793-78cm

I recently had my laptop black screen on me but everything seems to turn on.

I hear noise, the keylights pop on, I'm getting some USB devices to power, but no screen or backlight to the screen.
I searched on here for possible solutions. I've tried letting it die, removing CMOS, taking out the hard drives, external monitors, the reset button through the pinhole, but I haven't tried the RAM yet since I'd have to dismantle everything.

The issue started when the computer updated, froze, powered down, and when it reset it was just no screen.

I noticed a post from years ago about flashing the Bios.

I understand the concept of downloading bios to make the flash drive boot device, but I was wondering if anyone had the recovery file name that it needs to be set for the .fd or .bin file.
Additionally, if anyone can point me in the right direction for this model: Predator 17 g9-793-78cm
I've found walkthroughs for the other models, but I can't find the code for my model on here or using some of the other tricks.

I've had it for 5 years and it was a great computer. Worst case I know I can pull some parts from it and reuse those. However, I'd rather have a working PC again.

Thank you for any help or guidance!

Hi, you can try to do a BIOS recovery.

Here's the procedure for a Predator G9-791:

First of all, download the following file (BIOS 1.11 with the correct recovery name): drive.google.com/file/d/1zsz6F6HonvnlDbOJMHi6OzpncW4GkwFX/view
Then, do the following steps:

1. Copy the BIOS file to an empty and with FAT16/32 formatted usb stick.
2. Unplug the AC adapter.
3. Plug in the USB flash disk.
4. Press and hold <Fn> and <Esc>, and then plug in the AC adapter while still holding <Fn> and <Esc>.
5. Press the Power button. You can now stop holding <Fn> and <Esc>.
6. The BIOS flash should now begin, the fan will spin up and the power led should change its state.
7. After everything is done, the notebook will shut down.

In case you have another model, please post your model here, so I can have a look.

What did the computer update? Are you sure a bios update turned the laptop into a brick? The correct name is CHDRC.FD
But it is not allowed to publish the recovery method in the community.

I appreciate the help with the file name.
Honestly, I don't know for sure, but it's really one of the last options I have before I write it off as a loss.
I had a fresh install and was just going through the drivers from the website to update them.

You need to extract the bios file with the winrar program. Two .bin files will appear!

NightRevengeZ

Out of curiosity, I can't rename both .bin as the CHDRC.FD since it would be CHDRC.FD and CHDRC.FD (1)
Any idea if it will accept that or one one should be rename over the other. (MU5DC.bin and MURDC.bin)

Thank you for the help!
I won't be able to attempt this for another 4-5 hours so I'm just pre-planning everything.

Yes, it is necessary to rename the file. But it is almost likely that you will have to rewrite the bios.

NightRevengeZ

I just finally got around to trying to use the bios 1.14 and 1.11 but renaming it to CHDRC.FD as suggested for Predator 17 g9-793-78cm
I even tried renaming the two MU5DC.bin and MURDC.bin to CHDRC.FD individually and trying different combinations of the bin files and bios . exe files.

Sadly no luck when I formatted the flash drive and tried to flash the bios. This may be a bricked PC at this point sadly unless I'm missing something.
I know it started when it was updating which is why I think it is a bios, but either I'm missing something simple or it may be a lost cause.

It might be time rip it for parts unless there are any other suggestions for here. I know getting a new motherboard is like $700 for this model which probably could be pushed for another model.

If nothing else, I appreciate the help up to this point!

I would try to use an eeprom recorder, to rewrite the bios.

NightRevengeZ

Thanks for the idea. I was curious about them but didn't know about the "eeprom" as the name of the device.
I just got one but won't be here for a day or two. Iuckily, they aren't pricy. I'll follow up with results in a few days.
Now time to find tutorials in the meantime.

Thanks again for the support!

Final post, used an eeprom recorder with bios 1.04 to get the .bin file from that. I was able to have it start up with no issue. Just saved myself almost a grand! Thank you @edydiocoelho for the responses. It gave me what I needed.
There was a helpful post on bios-mods that finished the puzzle piece for me.

Thank you again for this forum and help!

@msmith123 i have some issue with reseting my bios password. I bought my laptop ph16-71-93FR from Acer and they sent me a locked bios, which i did not notice until i tried changing some settings. Can you help me reset my bios password?

After the 3 attempts, at the recovery window, it dumps a code.txt file (with more than 150 char long) in a usb, and it then asks for an unlock password. I suppose i need to type that down somewhere to get the password.
