Hello!
I've bought four T440p laptops. I've installed m.2 SSD disk, 16GB DDR3L 12800, cleaned the fans, changed the thermal paste and installed fresh Windows 10 Pro UEFI boot, Secure Boot on. Updated BIOS and all drivers.
Two of them are working perfectly, no problems whatsoever. The other two are extremely slow. I've erased the bios and reprogrammed them with the same dump from the working ones, changed the CPU, RAM, SSD, tried unplugging everything except the motherboard, tried installing Linux OS, Windows 7 on m.2 SSD and normal SATA SSD and still they are working slow.
What can be the problem? Everything is working but it is just slow. The boot time is over 20 sec on fresh install on SSD, the Explorer window takes 3-4 seconds to open.
I've also tried live boot from USB.. Same thing.
I have searched the forums and can't find anything. Most say about reinstalling windows, replacing the HDD with SSD, replacing RAM, etc. but nothing is related to my problem because I did that before I even noticed the problem.
Thanks in advance!
