Hello Douglas,
Thank you for reaching out to the Microsoft Community and I'll be glad to assist you today.
If your device won't turn on (meaning you don’t see any LED indicators on the keyboard, keyboard backlight, power LED, or if the screen remains completely off), this suggests a hardware issue rather than a software-related problem caused by updates.
When you install an update, it can sometimes mess with your operating system, which might cause error messages or throw you into an automatic repair screen, where you can try some recovery options to fix the issue or reinstall Windows as a last resort. However, if your device won’t even turn on, it’s likely a hardware problem. Here are a few things you can check:
- Try using a known working AC adapter and a different wall outlet to check if your device powers on.
- If your laptop shows any blinking LED patterns, note them and report them to HP hardware support. These patterns can help diagnose the issue and determine if hardware replacement is needed.
- Try draining residual power:
• Disconnect the AC adapter and remove the battery (if removable).
• Press and hold the power button for at least 30 seconds.
• Wait a few minutes, reconnect the power, and try turning the device on again.
If your device still isn’t powering on after all that, it’s best to reach out to HP for help. If it's under warranty, they should be able to assist you with any hardware replacements needed.
If your device turns on but you're seeing an error message, please share a screenshot or describe the error in detail so we can help troubleshoot the issue further.
I hope this information helps. If you have any questions, please let me know and I will be happy to help you further.
Best regards,
Gunasekar N
