Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm sorry to hear about your wife's laptop problem. The first question is, Does it work well otherwise, aside from the dim backlight? i.e. and especially, when you look at the screen in a bright direct light, does everything on the screen appear normal?
I think she turned down the brightness on the screen, which can sometimes be done by key combinations, through her rubbing the keyboard off.
(I presume though, that the decrease in brightness happened *after* the rubbing-off, not before - ?)
There may be another way of adjusting the brightness on the screen - the brightness of the backlight, strictly speaking.
(She is displaying it on a TV, right? is the image on the TV of a normal brightness?)
Have her try holding down the
key, and then press
key several times. That's the keystroke for turning up the brightness of the screen on many Lenovo laptops.
If that doesn't work, have her look on her keyboard's upper-row keys and function keys, for a bright-light or similar logo, and press that key after holding down the Fn key.
Has she restarted the computer since this happened?
If not, I advise trying that.
Let me know the result... or, has it already been tried?
What Windows version is on the Lenovo laptop in question?
Click advanced settings
click on Properties
click on the Driver tab.
After you click update driver, it will ask you how you want to search for driver software;
click on Browse my computer for software
Let me pick from a list of device drivers on my computer;
you'll see compatible drivers, look for
"Microsoft Basic Display Adapter"
click on Next.
That may help... but be sure to save all work and close all programs on the computer, in case it has a problem. And leave it hooked up to the TV if at all possible - that may be needed. This is a slightly chancy recommendation.
If those instructions run into a snag or are too elaborate or cause problems or simply, if you'd like to try another procedure, let me know.
OK, that must be the difference between Windows 8.1 and Windows 10.
I apologize to both of you, for giving inapt instructions.
Try this instead:
double-click on the Display Adapter entry, to open it.
go to the Driver tab. Let me know what information there is there, please. It's needed for further instructions in specific.
That's fine - take your time.
Doing something with that driver is the idea, yes.
Try Update Driver... if she has an internet connection, choose to search internet for appropriate driver.
Then this won't be simple and fast.
More time will be needed - at least 1/2 hour.
The driver must be refreshed... universally (almost) this common Lenovo problem is solved by re-installing the driver for the display adapter.
But it must be the right driver (even if a slightly lower version # i.e. of a slightly earlier release date).
So please tell me what the Driver Details says. In full, unfortunately, will be needed, as to the driver name and version #.
I had an internet access outage - please pardon the delay.
I am assessing the information you posted (and yes, catching up with one other customer) now that I can see it...
Pressing the F11 or F12 (especially) keys sometimes affects or locks up or corrupts (?) the driver for the display adapter.
This is unusual for a laptop. Lenovo may be criticized for this fault.
Driver version - thanks to your wife for typing in that no doubt tedious information.
I am looking for a reliable download for that... meanwhile, if your wife's laptop is Windows 10, it might matter that it is 32-bit or 64-bit... so please have her go to
System and Security
and look for the System Type, either 32-bit or 64-bit.
Thanks... will post again shortly (5 minutes?)
This page appears to be the right one.
Which of these does she download, Save, then double-click upon to Install ?
The one that matches both her Windows 10, AND also matches the 32-bit System Type - or the 64-bit System Type.
If this answers your question, please rate my answer. A five-star rating would be appreciated!

I'm sorry about that outage... it was actually a failure to load your case's screen, not just an overall internet failure. I had to do various things to get it working... the delay was, I hope, not my fault.
"Nothing happening" - in that what *has* happened please?
Did the intel logo appear, showing that the downloaded driver installer is executing/has executed?
Then have her re-adjust the brightness - NOT using the F12 nor F11 keys, unfortunately....
I regret to say that possibly the backlight has actually failed.
Try turning the laptop off for overnight, and see if it works in the morning, is about all there is left to say.
I hope to hear better news in the morning or tomorrow sometime.
Thank you for following this regrettable matter through with me.
