Hi

The laptop HP Pavilion 15-eh1006no with Windows 11 Home 22H2 randomly has black screen issue.

Not at booting, but in using sometimes screen goes to black. Power key has LED on, also keyboard has back-light but doesn't respond for keys pressing and within some time keyboard back-light coming off also but power key LED stay ON.

Lid cover closing/opening and touch-pad masturbating doesn't wake-up display. Short pressing power button also doesn't help, long pressing just switch the PC off.

Sometimes after this power button coming inactive for some time, but sometimes boots the system normally and black screen can come again within couple minutes or doesn't appear several hours. Periods of display stability don't depend on battery level, but seems plugged-in AC adaptor cause black screen issue more often than in battery running mode.

All drivers are updated to latest versions available from HP support page.
All windows 11 latest updates are installed.
Sleep mode setting is Never for all scenarios, hibernate mode is disabled.
What I can try more to solve the issue?

I am guessing there is a heat problem.  Laptops heat up when charging and running any intensive graphics combined with charging can cause overheating.

When on battery the CPU runs slower by design.

I assume you have used Air Duster.

Try keeping the CPU out of turbo mode when charging.  At the fastest speed the CPU can quickly overheat.

Try %95 for maximum CPU speed when plugged in.  If that works then try raising go %99 else try lowering it.

Edit your power plan and click on "Change advanced power settings"

Thanks BeemerBiker for the advise. 

Yes, Air Duster was used, also RAM modules were reinstalled.

Will try lower CPU powering and will report if helps, thanks.

Unfortunately lower CPU powering doesn't solve the issue. I have tried max. 95% and 90% also, but unsuccessfully.

Frankly I'm not sure black screen is caused by overheating, since laptop in these cases feels same warm as usually. AC adapter is OK also, since black screen also coming at using another similar HP adapter. Also have tried external monitor connected by HDMI, that says No Signal when laptop screen coming black.

Can you borrow another power adapter?  Possibly there is A/C ripple in the DC output or the voltage is not within spec.

This should be your adapter

741727-001

Smart AC power adapter (45 watt) - 4.5mm barrel connector, non-power factor correcting (NPFC) - Requires 3-wire AC power cord with C5 connector

It should be 19.5 volts at full load and any ripple should be %5 or less.   The Ryzen7 can draw up to 25 watts just by itself.  Possibly the charger voltage drops way below 19.5 and the A/C ripple goes up compounding the problem.  Just a guess.  Borrow a charger if you can.

Thanks BeemerBiker for your advice, but I have tried another AC adapter already loaning fully identical one from friend. He has another HP model laptop, but the same adapter. The reason of issue seems not adapter, since black screen appears in battery running mode also as well, when AC adapter not plugged in.
