This is an issue that I have been having for over a year on my Inspiron 13 7370. No matter what OS I use, Windows 7, Windows 8.1, Windows 10, ANY Linux distribution and yes, even Mac OS Mojave (it's possible, believe me), this problem persists between ALL Operating Systems installed on this machine.
Is it a BIOS issue? Is it an Inter driver issue? I have no idea.
I manage 20 of these machines in our school, all purchased in brand new in a lot and used as staff machines. I love these great little machines, but if it isn't the FRAGILE USB-C port, the sometimes lightly applied CPU compound causing the machine to overheat and burn the fans out, it is THIS screen issue.
Holding down the power is fine and all, and yes, it will reboot my machine, but what if I have a really long download going or a critical file transfer and I simply cannot plug in my laptop and keep the screen active? Oh yeah, then my transfers and downloads fail.
Please fix this issue, or at least own up to the fact that something is wrong.
Just so everyone knows, after the issues with these purchases, we in our IT department at the school opted to purchase HP laptops from our vendor rather than Dells.
I got the Inspiron 13-7370 for my daughter back in Dec 2017.
She had been complaining about this issue from day 1, but I assumed it was something she had done, i.e. some software she installed, a bad driver etc. I finally got sick of her leaving her computer on all the time (she disabled sleep mode to stop this issue) and have spent ALL DAY trying to fix it - going as far as completely reinstalling Windows (several times)
The issue persists. And after reading this thread, it seems it is likely a hardware issue. However, the warranty expired in Dec 2018.
I'm already behind monetarily - her battery is completely wrecked from leaving it on all the time so have had it replaced. Her screen is showing signs of wear too. This laptop was supposed to last her 3 years.
Is it worth trying to renew the warranty to get this replaced?
Or do I just ... well, never buy a Dell again?
If possible, I'd try force installing the older driver linked on page 8 or 9 of this thread. I don't run this as my main laptop, however this driver stabilized the issue for me for a solid week of testing. It makes sense as the issue didn't happen initially (and I bought the laptop in early 2018) but rather began *at some point* prior to January 2019.
