Windows 10: HP Elitebook 8440p microphone stops working after sleep

Hello, About a month ago I've encountered a very strange problem with my laptop. The microphone stops recording any sound whenever I put the laptop to sleep and wake it up.

HP Elitebook 8440p microphone stops working after sleep

Hello,



About a month ago I've encountered a very strange problem with my laptop. The microphone stops recording any sound whenever I put the laptop to sleep and wake it up. It won't work for an extended period of time, and sometimes it'll just suddenly start working again, I don't know why yet. The sound driver is installed correctly. I've reinstalled Windows Vista, Windows 7, and Windows 10 on this laptop and all three operating systems exhibit the same problem, so it doesn't appear to be a compatibility problem. Even weirder is the fact that the microphone itself clearly works because it works occasionally. Is there a way to fix this?

Sorry! Download it from here:

Scroll down to where it says 'Intel(R) HD Graphics' and press Download!

Let's see if it fixes it!

Cheers!

HP EliteBook 8440p - Product Information not valid

In that case, I think you're unfortunately out of luck. HP is the source for that information, and if they're not cooperating, your chances of finding out the required data are between slim and none ... leaning heavily towards none.

It's possible that an independent computer repair tech who has been in business for 10 years or more will know how to deal with that, but I wouldn't be very hopeful.

I was looking to find out how old your laptop might be in order to justify the 10 years in the above sentence and I ran across the following listing. Perhaps you should cut your losses. You would have to reinstall any application programs using original installation media and licenses, and restore data by recovering from your computer's drive, but for less than $200 you'd have something pretty similar to what you have now: https://www.amazon.com/Elitebook-8440p-Laptop-Notebook-Computer/dp/B00JW6O9EQ
