Problem Description

‎Device: Dell Precision 7730
‎Version: 26.04 LTS.
‎
‎So I’ve got a very peculiar issue with my laptop, the whole reason I got into this whole Ubuntu saga was because windows didn’t allow me to absolutely set my cpu to what I want without it boiling over.
‎This all started when the laptop got stuck on BD PROCHOT and refused to budge without a repaste ( which I won’t and can’t )making the cpu stiff at 800 mhz which is horrendous for the resource hoarder windows is. I installed Ubuntu and it ran pretty smoothly with 800 mhz but albeit slow because what can 800 mhz do in this day and age.so I wanted to tweak it a bit and installed cpupower and set the cpu upper and bottom floor to 2400 mhz while only setting it up to 3200 mhz for extreme work like managing web browsing and some editing. The laptop only reached a 100 degrees only a few times after which I toned my daily use speed down to 2000 mhz. The issue is when my laptop battery started failing, it’s making my genuine dell charger forget it was genuine, forcing another bottle neck which at this point i thought would be avoided by CPU power. It wasn’t. So when my laptop started this phase, it remembers the battery during usage and also forgets it time to time while it’s booted. Setting the speed by cpupower only changes it without load, the second you change its load on the system it gets stuck back to 800 mhz. Along with this, an issue with which the laptop has become unusable, the key presses are being registered either too slowly or register as like 20 at one time, this issue does not go away with an external keyboard and within the bios the keyboard works just fine. This is the reason I am posting because I have tried jus tabour anything, disabling sticky keys for Ubuntu, from terminal also and changing the keypress speed to no change. Any ideas on what I can do without just giving my system a hardware overhaul

What I’ve Tried

Tried changing the sticky keys version for Ubuntu, changing it via terminal, changing keystroke timings via terminal

Regarding the overheating problem: re-applying thermal paste is the absolute final measure and is only called for if the paste has gone bad and can’t conduct heat anymore. Before attempting that I’d try cleaning the inside of the machine especially fans and airways.

All the other symptoms seem to me to be possibly heat-related (either the heat making other components behave erratical or rapid/repeated changes in CPU speed breaking code).

You described some somewhat serious hardware issues and yet you seem to be looking for software side “solutions”, “fixes” or workarounds?

Ubuntu is a solid OS but it ain’t “magical”. Better to deal with the hardware for good.

While I agree with the other responses that it sounds like you might have a bigger hardware issue, one thing I would try would be to boot a live image of any Linux distro to see if the keyboard is as responsive as you expect.
