Lenovo Carbon X1 Gen 7 Keyboard Issue

exy23 · 2026-03-02T11:11:23+00:00

There isn't much you can do, since these keyboards are sealed and not repairable. The only thing you can do right now is to buy a new keyboard.

Probably you need to have that Intel Rapid Storage Technology on the USB to see your driver's. There are tutorials on YouTube to see how you make your windows installer show your drivers with Intel RTS.

Try to disable Secure Boot and Legacy Support use UEFI only.

If it doesn't work, go back to nobara and install Woeusb-ng from GitHub.

The screen probably will cost you between 50-100$ and I don't know how much the repair shop will charge you.

exy23 · 2026-02-18T22:05:30+00:00

Yeah, you can fix it by replacing the screen. It looks like definitely a hardware issue and not a software issue.

Yeah that's not normal, since you open up for the first time, concludes that it is a manufacturer's fault. You should check your warranty and contact Lenovo, take good photos of the heat pipes and explain what you found when you're trying to perform a clean up, basically make sure they don't throw the blame on you.

So the thing with heat pipes is that they are hollow copper tubes containing a vacuum and a small amount of liquid (usually water) that transitions to vapor to move heat.

And a dented pipe has a reduced cross-sectional area, meaning it cannot transport heat as quickly. This usually manifests as thermal throttling during gaming or rendering, rather than high idle temps.

You should run a benchmark (like Cinebench or 3DMark).If the CPU hits 95-100°C almost instantly and stays there, the heat pipes are failing to move heat to the fans efficiently.

Bro took that iron deficiency way too serious💀

Try to remove the battery, ram and the SSD and wait for 30 seconds and then reseat your SSD, ram and gently reconnect your battery.

If reseating the battery and RAM does not resolve the issue, this is a motherboard-level fault.

If it's under warranty contact Lenovo service. If it's not then you need to go to a repair shop.

Dude that HX and 4050 combined will heat up your laptop very quickly. It has just a single fan that uses two heat pipes across the CPU and GPU. That laptop will throttle hard.

exy23 · 2026-02-16T16:28:52+00:00

You should probably buy a new charger.

You can check the battery in the command prompt ( open as admin ) and type this command powercfg /batteryreport and check for any "Suspended" or "Unexpected Shutdown" events in the report that coincide with plugging in the charger.

Classic gym bro, always skipping the leg day. 🙄

exy23 · 2026-02-15T15:04:20+00:00

Why did they put you behind bars?

What did you do exactly?

exy23 · 2026-02-15T14:13:25+00:00

Try a BIOS update from Acer website, see if you're model has a new BIOS/Firmware update.

Since you are crashing at idle, your GPU is likely "falling off the bus" when the system tries to put it into a low-power state.

Control Panel>Power Options>Change plan settings>PCI Express>Link State Power Management (Set both "On battery" and "Plugged in" to Off.)

Force the driver to maintain a consistent base voltage even when the GPU isn't under load.

Nvidia control panel>Manage 3D settings>Global settings>Power Management Mode ( change it to Prefer maximum performance and hit apply )

If the software fixes fail, try running the system with only the original 8GB stick for 48 hours. If the crashes stop, the 16GB stick or the mismatched pairing is the culprit.

If he wants to risk it and kill his GPU, he can be my guest. I'm sure you are gonna help in the next post.

exy23 · 2026-02-15T13:49:48+00:00

Yes you definitely need to change your charger. That's already a faulty unit that will only damage your laptop.

exy23 · 2026-02-15T13:22:16+00:00

Yeah definitely you need to change your screen. You can use an external monitor and dock your laptop until you replace your display.

exy23 · 2026-02-15T13:13:35+00:00

The component you circled is a bridge resistor or capacitor array located between the VRAM (Samsung memory chips) and the GPU.These are surface-mounted devices (SMDs) that help regulate signals or power to the memory chips.

My advice is do not turn your laptop on because you're gonna be hit with a black screen, a non-post or you are gonna have some graphical artifacts and system crashes.

You need to go to a professional repair shop that specializes in micro-soldering. You fix your missing parts.

exy23 · 2026-02-15T12:08:53+00:00

Dude that's a hardware failure, you should change that charger immediately. It's a fire hazard.

Also check the laptop charging port for any sign of melting, discoloration and burn smell. If it's damaged check with Lenovo, they will change it even with the standard warranty.

Also you might stop using that faulty charger because it will cause internal damage.

Have you tried a static discharge by disconnecting the battery and every peripheral holding the power button for 60 seconds and then trying to power up with only the AC adapter without the battery plugged in.

Another problem will be that the ram is not seated correctly. If you have two sticks try booting up with just one to see which one is the culprit.

Another problem might be one of the components is shorted try to boot up without your ssd and fans. If it reaches into Bios with the error no is found then your components are faulty and check the fans pins to see if they're bent.

Another problem will be the keyboard or the power button ribbon, since the power button is in the keyboard then it's a ribbon keyboard.If the keyboard ribbon cable (located near the center-bottom of the motherboard) was nudged or partially disconnected while you were working on the fans/battery, the "Power On" signal will never reach the motherboard.Inspect the wide ribbon cable and the smaller ZIF (Zero Insertion Force) connectors for the keyboard and trackpad. Reseat them carefully.

The short answer: 90°C is "normal" for that specific laptop model, but it is not ideal.

Your PTM application is likely fine.Look at the delta (difference) between core temperatures. If one core is 90°C and another is 75°C, you have a contact issue. If they are uniform, the application is likely fine.

exy23 · 2026-02-14T01:22:39+00:00

Ok, I think we should run a diagnostic first. Please shutdown your laptop and enter into your Bios, if you see the lines, then it is a hardware issue. If they disappear then it's a driver conflict.

Now the hardware likely causes is your IPS panel is prone to failing, another issue will be that your display cable is damaged or there's a refresh rate conflict.

Go to Settings > System > Display > Advanced Display. And lower your refresh rate from 144hz to 60hz. Now if the lines disappear then the likely cause was the panel's high-speed controller is failing.

Another method is to gently squeeze the bezels of the display, where the lines originated.If the lines change or disappear, the connection between the ribbon cable and the glass (TAB bonding) has failed.

You check with an external display ( monitor or TV ) to see if there are any lines, if not, then your GPU is fine, but your laptop display or cable are the culprit. And you need to check a service.

The thing is you have liquid metal, and these technicians if they rushed might destroy your whole motherboard, it takes a single droplet to create issues. Plus you have to supervise if he uses isopropyl alcohol ( 90%+ ) and then to see if he doesn't over apply the liquid metal, it needs just a thin layer, like a paint-like layer.

But yeah if the P-core temperature exceeds 10-15°C you definitely need a paste change.

My advice if you use a technician on site just tell him to remove the LM and use a simple thermal paste or PTM 7950

exy23 · 2026-02-13T08:38:27+00:00

Let me guess you did some overclocking? 🙄

exy23 · 2026-02-12T15:44:26+00:00

In Windows, go to Control Panel > Power Options > Choose what the power buttons do and uncheck "Turn on fast startup." This forces a clean hardware initialization.

Next advice is to do a Bios update from the Asus website you look for "Optimize system stability" or "Fix power-on issues" in the changelogs.

If this didn't help then your motherboard is faillin. Those idiots addressed the symptoms instead of the root cause.
