The screen stays black after waking from sleep or hibernate despite the power indicator being on, and the other buttons (e.g. Airplane mode) still functioning. If I connect it to an external monitor the computer is actually running as normal (though, the original micro HDMI port does not function, and I have to use a USB to HDMI adapter). The issue happens whether or not I am plugged into power.
This has continued over the last few years and is not getting better or worse, and seems to happen randomly.: it will occur every time the laptop wakes on some days, and then not again for a week or more. I don't have any other display issues (no flickering etc)
The only way to fix it temporarily is to hold the power button for 45-60s and then release, forcing a reboot. The solution was suggested by bestbuy.com/geek squad appointment team, he also suggested that this will be permanent fixed after physical check.
Try to change the sleep mode settings for the options "Turn off hard disk" and "Sleep after" to "Never" under the Power Option. Select "Power buttons and lid" from the drop-down menu. You can also set the "Put the Computer to Sleep" option to "Never" in your "Power Plan" options. If none of these options will work, then it might be a screen problem. You can go to a master and try to repair it, but if it's already an old model, I think that it's better to buy a new one, especially when you can find 144hz monitors under 200$ on how2pc.
