Hi @Lyn11,

Welcome to the HP forums! It is a great way to engage, post questions and find resolutions by working with specialists in the HP community. I understand that your computer’s HDMI port does not work after a windows 10 update. It will be a delight to assist you here.

 Real smart work to analyze that the computer’s HDMI port may have stopped working after this recent windows 10 update. Commendable job! Kudos to you for that. We value your relationship with HP and greatly appreciate your business with HP. I take it as a privilege to share this platform with you.

We need to diagnose correctly if the issue is hardware or software related.

Please try these steps:

1 - Open Device Manager. Right click on the Start Menu Button (The windows logo in the bottom left of the screen, YES you can right click it in Windows 10), and select Device manager. 

2 - Find the Graphics Drivers

3 - Right click on the Graphic Driver (If your laptop has an integrated card you have to right click that one) and select Update driver

4 - Select the bottom option, for Search drivers in your PC

5 - Select the bottom option again, for Search from a list.

6 - Select a different version from the one you already have. If you have an integrated card, you need to select the older versions.

7 - Click Next, wait for it to update the drivers, the screen will flicker for a while.

8 - Restart your PC, if it doesn’t help, please post a picture of how the Device Manager window looks in your PC so we can see what you have on the laptop.

If this does not work, you could visit this link to update your graphic card drivers from the HP support  site: http://support.hp.com/us-en/drivers/selfservice/HP-15-Notebook-PC-series/7486447/model/8073954

Please make sure that you update the correct display drivers from the list that matches your computer’s graphics card.

Hello David

Thanks so much for your answer, I'm sorry I didn't answer before, I've been away. Have tried all your steps, but still no luck. Tried to update driver, but get message to say "best driver software already installed" I've tried "select HDMI output as default audio device" but only have "speaker/HD as default device" I shall attach print screen if it works, and will keep my fingers crossed that you may be able to solve this maddening problem!

 Please help, my hair is growing greying by the minute, and my husband will soon divorce me as I spend hours on internet trying to find an answer!

Regards

Lynne

Hi @Lyn11,

I read your post and I thank you for your reply. I reviewed it and I'll do all I can to assist you here.

• First off, you'll need to update the bios and chipset drivers from the above-mentioned link.
•  
• Later you will need to uninstall the existing audio and graphic drivers and then visit the HP support site to download and reinstall both.
• Please check this link out as well: http://h30434.www3.hp.com/t5/Notebook-Audio/HP-15-TS-Notebook-PC-HDMI-port-not-working/m-p/5767345/h...
• Finally, you may need to roll back your windows 10 build to a previous version of windows. 
• If it is a recent update you could use the go back feature in windows to roll back the operating system. Link: https://support.microsoft.com/en-us/instantanswers/1235b5b0-bf94-4b77-9cbd-1c1a8337070c/going-back-t...
• If you had installed windows 10 and updated it again to a newer Windows 10 build, then you could perform a system restore to an earlier time before the problem occurred. Link: http://support.hp.com/in-en/document/c03327545
• If nothing works, the only alternative would be to perform a complete system recovery to factory settings from this link: http://support.hp.com/us-en/document/c03489643

Please note that the system recovery would wipe the drive clean and restore it to default factory settings.So please backup all your files before attempting it.

Hope this helps. Let me know how this goes. I hope the issue gets resolved without hassles and the unit works great.

To simply say thanks, please click the "Thumbs Up" button to give me a Kudos to appreciate my efforts to help. If this helps, please mark this as “Accepted Solution” as it will help several others with the same issue to get it resolved without hassles.

Take care now and have a splendid week ahead.

Hi David

I am trying to update bios, but need the product key no. and I can't read it from the back of my laptop as it is scratched. Is there another way or finding it please?

Hi Lyn11,

I thank you greatly for your quick reply. Yes, there are ways to locate the product# and serial# of the unit. 

• On the desktop ,(first screen of windows with all programs closed) please press this key combination to bring up the system information which will also give the product# of the unit. Please write it down along with the unit's serial#.  Do not post your serial# information on HP forums. Press the fn key (function key) along with the "Esc" key on the keyboard simultaneously to bring up this information.
•  
• You could also locate it in the bios. Please power down the unit.  wait for a few seconds and as soon as you power it back up keep tapping the "Esc" key right away, gently several times.
• It will bring up the startup menu. Then press the F10 key to go to the bios. The bios will also give the serial and product number information.
• A third way to locate the product# would be to power down the unit. Disconnect the charger and remove the battery.  Then use a flashlight to look inside the battery compartment to locate the product#.

Please visit these links that could provide more useful information.

Sorry David still having bother with HDMI port, I have followed all your instructions, updated BIOS, chipset drivers, graphics drivers, audio drivers, and then as a last resort did a system recovery to factory settings this morning. Now I am back to windows 8.1 and still no HDMI port! This suggests it was not a problem with windows 10 update as I thought! BIOS ID is F.40, disc drives SOHC card ST1000LM024HN-M101MBB whatever that means! Does this now look as if my HDMI port is broken? I recently sent my laptop for repair and when it came back there seemed to have been a problem with the motherboard, so if that was replaced could that have damaged the HDMI port? We live in France, so laptop was sent to french technician, so not easy to find out exactly what they did! Any other ideas please, or should I just accept the fact I don't have HDMI?  

Thanks

Lynne
