Uninstall and reinstall the Universal Serial Bus controllers driver can be an effective fix . Reinstall the Universal Serial Bus Controllers Driver Incorrect or outdated card reader driver can make the SD card unrecognized on your Windows 10. If your SD card doesn't show up in Windows 10 File Explorer, check whether there is a drive letter. Full stepsĪ dirty SD card or a dusty card reader will cause poor contact and make SD card not reading. the flash utilities that come inside the archive from HP, won't work on Windows PE, which I've tried to use for several hours.You can connect your SD card to another computer, or alternatively, try another SD card. The DVD/BD-Combo drive is a little bit broken on this laptop, so I couldn't boot from there. It took two attempts at flashing the BIOS correctly, but after that, the keyboard works just fine. The Flashing tool comes from a rather dubious location on Mediafire, I have no idea where this program originally comes from, there was no URL to be found in the program, etc.Īfter puzzling a bootable, minimal FreeDOS, with the flash tool and the ROM image, I've installed the SYSLINUX bootloader onto the USB stick, and booted from it. fishing out the correct ROM image required several hours and a Virtual Machine, as well as a lot of hair-pulling.Įventually found a program (from Insyde, actually) that'll run on DOS, so FreeDOS it is.

The BIOS comes with a weird update tool from Compal, the Chinese company that built the chassis an the motherboard of this laptop. What have I done to fix the Numlock issue? Upagrading the EFI BIOS, which was nothing easy to do.Īs a Linux user, I made a FreeDOS boot image, and booted from USB drive. I don't know what caused it, but it seems the BIOS got corrupt at some point. The "InsydeH2O" BIOS had to be flashed from version F.0A to version F.2D. OK, I managed to solve the problem, and it wasn't obvious at all. I also tried setting the flag and LED on the linux console with setleds +num: setleds -v now reports the flag and LED is set, but the Numpad is still not working, and the LED isn't on either. I tried setting the Numlock status programatically under X with numlockx on: didn't work. Any ideas how I might solve this? As the keys do absolutely nothing, I have no idea where to even start. Now, I believe because of the "duality" of the nature of this keyboard, it confuses the driver.
I discovered, some other, weird behaviour with the Fn-key: When I hold down Fn, and press 'jkl' I get '123'! So, it's as if there was a laptop keypad embedded onto the main block (as it is quite often, when the keypad itself is missing). The keyboard has an Fn key, to access some media keys located under the F-keys. When testing the keys on the console with showkey and on X with xev, the keys do absolutely nothing, all other keys send keycodes as expected. However, I don't believe the keyboard is physically damages, as it worked OK on Windows, and the four buttons right above the keypad, at the top edge, work fine. None of the keypad keys seem to produce any keycode, Even Numlock won't turn on. The keyboard works as expected under Windows, but on Linux, I can't get the keypad to function.

I've recently got a HP DV7 laptop for free from a friend:Īs you can see in the picture, the laptop features a (modified) full size keyboard, including numeric key pad.
