Boot issue and POST issue are two different things.
Disconnect the SSD from the motherboard and check if you get the splash screen or a message about no OS etc on the screen.
If you do then try to get into BIOS by starting the laptop and pressing the Novo button and then selecting BIOS setup.
''If you get the above'' then POST is OK and there's a problem with the OS (or the SSD - doesn't have to be hardware it may be corrupted software). You can't get into BIOS if POST fails.

Try starting the PC a few times just to make sure that you can access BIOS every time quickly as it may be intermittent since you say it eventually boots into the OS
Is Linux the only OS installed or is it a dual boot?
Was it a clean Linux install i.e. having no Windows OS on the SSD or a brand new SSD etc?
''If the above doesn't work then there's an intermittent POST problem'' (given that the laptop eventually boots OK), which is hardware related i.e. motherboard components or BIOS firmware.
POST checks that everything that is necessary to get the PC to be able to begin to boot into an OS e.g. CPU, ram, video controllers etc are working. If not usually there's a error code given by a blinking light/colour pattern with the various lights on the PC i.e. Power, Caps Lock and Num. Lock
