Backlight not working and keys not working intermittently

[boysonfire]

Had problems with this computer from the begining. Would turn on with lid closed from sleep and heat up and eventually wouldnt boot. Think it was a system died error. Anyway reinstalled/reset using microsoft key and all seemed well. After an update noticed backlight stopped working. Performed a hard reset and wouldnt boot or re-install this time. Returned to shop and they installed windows 10 etc. Just noticed the backlight doesnt work and the keys are not working. Sometimes they do and sometimes they dont and it happens with all keys. Any ideas what can be causing all these problems as after decades of owning laptop i feel as if there is something fundamentally wrong with my particular model. Thank you in advance

Welcome to HP Community

I have gone through your Post and would like to help

Since you reinstalled Windows, I suggest you download and run the HP Support Assistant from this Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...

HPSA will automatically search for all the latest drivers for your Notebook

1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

   

2. Click Check for updates and messages to scan for new updates.

   

3. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.

4. Click the update name for a description, version number, and file size.

5. Select the box next to any updates you want to install, and then click Download and install.

Also ensure Windows is up to date.

Select the Start  button, and then go to Settings  > Update & security  > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available

Keep me posted how it goes

Thank you and have a wonderful day 😊

Hi thanks. HP assistant is loaded but today my laptop went black screen made clicking noises then lit up again with a different display ie 150% rather than 125%. I looked in task manager and hp update was running. this ran for hours until i stopped it. i then looked in HP assistant and there was an update for AMD high def graphics driver with red !. I tried to download and now it say dismissed at the top and installed at the bottom. Dont understand why hp update was running using 39% of cpu

Try running the AMD Auto detect Tool. Link; https://www.amd.com/en/support

Backlight stopped working twice yesterday and on one occasion keys stopped working properly. Closing lid and putting to sleep solved on wakeup.

i only had one optional update for realtek but dare not do that if not needed

Since this issue is intermittent, I suggest you perform a Reset

Hi, i reset a month ago and a couple of weeks later it started again. It then wouldnt start up and i couldnt reset, restore or safe boot. I had to take it back and they reset installed windows and it has started again so as i said could it be that there is something noit fixable wrong
