I recently updated my BIOS from F.04 to F.05 and then some of they keyboard keys would not function normally. I would have to press the backspace key repeatedly to delete mutiple letters rather than holding the key down. I was able to solve this by holding down the shift key and then holding down the backspace key to delete multiple letters. I also found the same problem with the g, h, and n keys. I had to downgrade the BIOS to F.00 to get the keyboard to work normally. I could not find a F.04 file.

 

Is this a common problem with F.05?

 

Thank you.

 

Edit: F.06 still has the same keyboard problems.

F.07 has been released. Time to get testing!

 


- Provides improved proximity sensor performance. 
- Fixes an intermittent issue where typing rapidly on the keyboard causes keystrokes to be dropped.

I am running into the exact same issue after this BIOS update (b, n, g, and backspace keys skipped).

I noticed that the keyboard works perfectly well when the laptop is on battery, but the problem reappears as soon as the battery is  fully charged. Very strange and really frustrating!!!

I wish I could downgrade, but I can't even find any previous BIOS release.

Are we the only ones having this problem?

Have you both tried to enter BIOS setup and "Load setup Defaults" then save and exit?

HP Recommended

I emailed HP about ths and they said it isnt a reported problem, but Im sort of glad Im not alone with this problem.

 

Ive already tried loading defaults in the BIOS, setting the keyboard delay to short and repeat to fast, and unistalling the keyboard from device manager. Nothing.

 

When my laptop is running on battery, they keyboard works normally.

 

Now HP is giving me the standard safe mode troubleshoot. I dont think its a software/OS issue.

I don't know what did change, but the problem disappeared as mysteriously as it started.

I don't think changing settings in the bios did help (but I cannot be too strongly affirmative as I tweaked them a bit).

But, for the most of it, I just let the battery discharged, I shut down the laptop, re-plugged the AC and the keyboard was working well again.

I hope you will be as lucky as I have been.

So you just used your laptop on battery untill Windows forced you to shut it down?

 

I got a link to the F.04 BIOS, but I want to try the battery drain first.

The problem was suddenly back this evening! 

It seems to have reappeared when I forced an application to used the AMD GPU instead of Intel HD. It has to be related to the switchable graphics, but it doesn't seems to be software/OS dependant: I have a ArchLinux dual-boot (where I only use the integrated chip) and I encountered the same keystrokes problem.


I don't fully drain the battery, but I guess that - somehow - shutting down the laptop on battery forced it to reuse the integrated graphic chip when restarting... it seems to have done the trick again this time (I just shut down the laptop after letting the batter discharge a bit, I restarted on battery and then re-plugged the AC).

Well, the keyboard gets messed up when the battery is at 100%. They keyboard is fine when the battery is charging or discharging. Im going to pass the findings to HP and test out the F.04 file they linked me.

 

Edit: The first link they gave me was for the F.04 BIOS for the dm4. HP said the only way to flash back to F.04 is through a service center...which is such a lie. I dont see why they cannot make a file. Now the only option is to stay with F.00 and wait for F.06 to be released. I dont know why I bothered updated to F.05 when the description on the HP website is all in asian characters.

Edit: False alarm, the problem came back after I restarted my computer.

I, too, am having th keyboard isue after updating to F.05 earlier today. The most anoing part about his is that there's no way to roll back to F.04 I've verified so far that as long as the AC adapter is not plugd in, the keyboard wors just fine (similar o what a previous post above mentioned, but for me, the oly defnite way to avoid missed keys is to run on batery).

 

Annoyed by my many typos in the last paragraph? Blame it on HP, b/c it's the resul of all the mised keys resulting from F.05. Honestl, I've been overlooking al of my annoyancs w/ his laptop so far (thebiggest anoyance being regarding the inability to produce RED colors), but HP, come on--enough is enough!
