Please help me! Everything is working fine as expected but the only problem i have with my t440p is that when i connect the charger the Hackintosh reboots randomly....
Did you upgrade your CPU?

You may need a higher watt charger for your CPU if you are getting reboots when plugging in AC power.

I have a fairly slow i5 cpu, would that really be the problem?
When I upgraded the stock i5 to the i7 4910MQ, the laptop would reboot black screen and warn AC is not sufficient. It needed a 135w charger instead of 65w to run.

Things you could try:

- Booting in safe mode from Clover and see if the reboots still occur.
- A different lenovo charger that matches the power requirements of your CPU.
- Check your BIOS settings to see the behaviour of your laptop is correctly specified under AC power.
- Update your drivers and BIOS with Lenovo Vantage.

I would expect the issue is with your charger if your laptop is stable with battery.

I have a 90W/20V charger maybe thats the problem? it is too much? what is weird is that it did not reboot with the same charger when it had Windows 10 installed.

90W is fine.

I suggest you use a known EFI like jloisel's to see if the reboot issue is with your own config.plist.

Back up your machine before doing so.

Hi everyone.
I just got my t440p and I'm trying to install catalina by jloisel's guide.
When I boot from the USB with the right options set I get a hangup of about a minute or so where it says "Incompatible CPU" and "Incompatible PCH".
After a while the installer boots but at that point my keyboard nor my trackpad are functional. When plugging in an external mouse and keyboard, those work just fine.
But now when I try to continue the installation I get an error saying I need an internet connection to install MacOS, while I just have a known working LAN cable plugged into the laptop.
Have you got any idea on how this problem could be solved?

When it says to move kexts into /Library/Extensions does this mean I should remove them from the EFI partition (clover/kexts/other)? Or should it be a mirror? It's confusing...
You should move them, not copy.

Put them into /L/E and remove from efi partition

I was able to create a new USB Kext that enables all the USB 2.0 and 3.0 ports on the laptop, integrated camera, bluetooth, and all the USB 2.0 and 3.0 ports on the ultra dock. I've been using it for a few weeks and have had zero issues. I am on Mojave... not Catalina. I attach the kext i made to this post.

In addition, I finished a fun mod to the T440P to replace the factory power adapter with a USB-C power adapter. In my case, I'm using a 87W Apple power adapter. No issues whatsoever and gives me much more flexibility when needing to charge on the road and carrying one fewer power adapter since the USB-C adapter can pretty much charge anything.
