Sager NP8651 Keyboard input "stuck" in video games.

I bought this custom laptop in 2014, and ever since it has worked perfectly fine. Originally, it came with Windows 7. I upgraded it to Windows 10 around 4-5 months ago. Since the upgrade, and whenever I am playing video games (Battlefield, Minecraft), some keys' input gets stuck if I hold down on a key for too long. For example, if I am holding down the W key to move up my character, and I hold down on it for more than a few seconds, the character will still keep moving even after letting go of the key. It subsides eventually, but it's getting to the unbearable point. I remapped my keys to move over from WASD to ESDF, and it was back to normal at first, but then now it's starting to do the same thing. It's not every key, and it's only a few like W E D. This ONLY happens in video games, and it's in ALL video games. After the problem activates, I sometimes, but rarely, get one of those keys unregisterable, but that goes away really fast. The whole problem never occurs while browsing or surfing the web.

I don't have a disposable keyboard to plug-in and try to see if it still is happening. I went and unchecked tabs in Device Manager that allowed the computer to stop some key operations to save power when in use. I contacted customer support, and they were unable to help me. My BIOS has not been updated since I got the laptop. I have vigorously cleaned and removed the affected keys to airblow in it. I do not have a warranty, and would rather not ship it off somewhere. Nothing has worked so far. I also changed the Delay Rate and Delay Speed for the keyboard, and got nothing. I do not know if this is a physical or software problem. Hoping there is a solution that I can make happen. If you need more information from me, I will certainly tell you.

(I tried two threads in Tom's Hardware but got 0 responses.) Any help would be appreciated, thank you.

 

How are the temperatures in the computer? I believe this has come up a couple times in other threads, and it was thought that the temperatures in the computer could cause issues with the keys at some point. I don't know if it is 100% the cause, but it has come up before as a potential cause.

This is one of those threads:

Just played a full match: In a full 64-player server on Battlefield 4, I reached a maximum temperature of 83 Celsius on one core, the other cores maxes were 75-80. The average was low to mid 70s.

I recently cleaned my laptop around 1-2 months ago, as the temperatures were reaching 80s-90s. After cleaning it, the above temperatures of 70-80 was a normal average for most intense games.

 

Can you run a stress test on the CPU and GPU in windows and see if it happens in a text document too?

 

Do you have a specific program I can use for this? I do not really know how to do that. I also do not know what you mean "in a text document."

 

Just any benchmarking program should work to stress the system. You could even run a game for a bit, let the system get hotter, then tab out and see if the issue is still happening in non-game programs.

 

I'm playing on Minecraft right now: Temperatures are at mid 50s-mid 60s,(now it's in the 60s) and it's doing it. I tabbed out and tried it on the browser search bar, held on/let go and it just kept going. Once it activates on a game (temperatures maybe? idk) it'll transfer to anything, apparently.

This may just be in my mind...but it also seems proportional (not exactly) to the length I hold onto the key.

 

I had this before, you will need to replace your keyboard, it only went away after I replaced mine.

 

How do you replace a laptop keyboard? Especially a custom model one like this (and where to buy)..? And how do you know that's the only solution..

 

By removing the two screws that hold it place, then gently pushing it out and, also gently, removing the cables from the keyboard to the motherboard. A part number is on the back of the keyboard; you can look that up online and shop replacements or contact your reseller about it.

 

No horrible glue like some manufacturers like to put on!

 

So you also think I should replace the keyboard too?
