Precision M4600 Owners Lounge

Ok, that's what I was looking for, thanks. Btw the brightness control works really badly also with the Quadro 2000M so I don't think it can be worse than that.

 

Ok, I've finally upgraded to the M5100 but one thing doesn't want to work. THE BRIGHTNESS CONTROL. Is there any way I can force windows 10 to do it?

 

Nope, never worked for me. Set in in BIOS is the best you'll get

 

What about software dimming?

I never messed with 3rd party apps

 

Ok, after the upgrade another problem came up. Sometimes the laptop won't load win10. In the bios log i get a CPU power off or something like this and the light error code is:
hdd - blinking
battery - solid
wireless - solid
It's not a really big problem but it's frustating having a laptop that doesn't want to turn on after having the win10 loading wheel if you're on a hurry.

 

This might be problem with some HDD/SSD installed on your computer, i had troubles with my laptop when i had SSD Kingson model V300. He coudn't boot until manually forced from boot options. What is your OS HDD/SSD drive?

 

I've got a used Samsung EVO 850 (used by me in a previous build) but I don't think that's the problem. It seems to be something like an overload of the psu because it only happens when fans start spinning at high speed during boot. Everything else is good and boots like it should. It's now 3 days that it's booting normally.

 

Just a few days ago I plugged in my 200w hp charger by mistake and ever since the keyboard fails intermittently.
Most of the time it won't even work on the login screen upon boot up and if it does, i'll stop working after a few minutes of logging on.
Taking out the battery and hold down the power button for 15 sec and than plug it back in and reconnect the charger increases the change of it working again at the login but eventually stops.
I even did a store of of the system, only the files but still having this issue.
It wouldn't even work when windows 10 asks me to enter a user name during set up and had to take out and reinsert the battery numerous of times before the keyboard would work again.
If I had damaged the circuit where it emitting power to the keyboard, it should stop working completely.
The fact it's fails intermittently is what's confusing me.

 

Maybe you might try removing the keyboard altogether and plug it back in. Its also possible you may find visual attributes that shouldnt be there.
