L44887-001 HP ProBook 440 / 450 G6 Laptop System Board
[L44887-601,L44887-501,DAX8JMB16E]

5 of 5 Stars I bought one of these motherboards and replacement was not very difficult. Re-assembling the laptop took 30 minutes maximum and switching on it my Probook 440 G6 came to life with no issues. Two months now and counting and the laptop is quiet again. I have also upgraded the memory and it feels as it is a bit faster. It is a quality board and came with great packaging. I'm also happy that I have a year warranty incase something goes wrong...
