HP Notebook 14-ck102tu 5EA35PA#UUF
Microsoft Windows 10 (64-bit)

Hey. So recently I've been experiencing some minor issues with my laptop like the battery icon disappearing everytime I boot up or LED indicators not turning on. So stupid me thought it was a good idea to update the BIOS. I went to Device Manager and looked for Firmware and updated it there. It downloaded, restarted the computer and it brought me to the BIOS update confirmation at bootup. It seems to have went smoothly and finished without errors.

 

Skip to about an hour later and Im still staring at a black screen. I tried the bios recovery combination by pressing Windows + B and holding the power button for a few seconds but to no avail. I tried pressing f2 when turning on the computer and tried to Rollback my BIOS (now F.61) back to F.47 but it keeps saying that it "cant open signature file". I tried flashing the old BIOS version (F.47) too but it also says it can't read the signature file.

I tried flashing an even more up to date BIOS (F.62) that I downloaded from the website through usb flashdrive but the HP Logo just pops up along with a loading animation and then goes into a blackscreen after a few seconds.

After messing around with it for the whole day trying to find anything that could help, I noticed that it does seem to boot into Windows and the system itself is running. Whenever I plug a usb flashdrive in, it plays the sound. If I press capslock or f6 the LED Indicators light up like normal. When I press Alt + f4 and press enter, the computer actually shutsdown. And when I leave it alone for long enough it actually goes to sleep mode, but then the monitor never turns on after.

I really wanna save factory reset as as my last resort because I have loads of work and data in this computer and I do not have easy access to an external hard drive large enough to hold all of the data in this thing for backup.

I pray to the Gods and Primordial beings out there that there's something I can do to save this laptop.

 

Here's the Log when I tried flashing the older version f.47:

Update: I think I can confirm that Windows itself is actually running in the background like normal. It just cant seem to display anything. I can hear all the sounds and notifications and it connects to my phone's hotspot. 

 

I don't have access to an HDMI cable right now to text with an external display, so I tried using another laptop and connected them the same network, and tried to project the display. After a few minutes of blindly clicking around trying to click he Ok button somewhere in the corner. I managed to connect them. As i tried duplicating the display, the other laptop also showed an entirely black screen.

 

Im guessing maybe the video drivers aren't working properly with the new BIOS..??

 

maybe someone can provide me an older working bios? I cant seem to find F.42 anywhere, only F.47(which doesn't flash for some reason, log says it's incompatible) and F62(still doesn't fix blank screen), both firmwares I got from the product's own software.

Someone help me pls 😞
