Got a HP Probook 450 g5 that will not boot. I press the on button and it will turn the LED on for a second then turn off no beep code or led code to show where the issue is it just turns on then off again. If I take the RAM out it will do a beep code for RAM not being seated correctly. But that is all I can get. I have stripped it to every individual component used compressed air on mobo to make sure jo dirt etc creating and issue and then re built still doing the same thing. Any suggestions? I have been through the obvious like do a hard reboot. I have changed the RAM with another stick same size memory and mHz. I have tried a different AC adapter. And have tried booting without RAM or the nvme installed to see if that was the issue but it still won’t boot.
I assume the issue is MOBO the internal battery or cpu but is there anything else I can test or do to try get it to boot before having to give in and get it recycled?
Thanks could really do with assistance on this one!!
