Display turns off when laptop is opened beyond 90 degrees (approx)
When I open my laptop's lid beyond a point (say approx 90 degrees), the display turns off while the programs are still running.
This problem initially started at more than 120 degrees (which was not affecting me much). But it deteriorated gradually to around 90 degrees now.
The problem is consistent (happens at any time of the day and usage).
Currently using the laptop by not opening it beyond 90 degrees and adjusting my seat. No other problems exist. Works fine if I use it this way. But it's getting frustrating and soon it will deteriorate further to <45 degrees making it unusable.
It's definitely a HARDWARE issue related to the screen.
I live in India. This is a Lenovo B490 laptop.
Can somebody please point out which part is malfunctioning and what to do about it?
Is this a good question?
