    Make sure that your screen plug (see below) has not been disconnected from the motherboard

    If your screen worked before you cleaned the cpu and gpu then the screen should work, check that you haven't damaged the plug and all its delicate wires as the screen wires are very delicate and can be damaged very easily! This happened to me and I thought that the screen plug was 100% connected but it wasn't and I had to repair the wires and put extra tape for the wires to make proper connections with the plug. There should be no other reason(s) why your screen should not work if it worked before you opened the laptop unless, the cable from the LED screen or the LED screen was faulty before you opened the laptop.

    Sounds like the motherboard can't reach BIOS. The BIOS may have been corrupted, OR the motherboard is damaged in some way.

    Technically it could be the CPU or the RAM too. The computer won't boot if these are faulty in any way. Try taking out a RAM stick, repeat in both slots.

    Hi @byambatogtokh
    ch​eck if there is a pin 📌hole at the bottom of the unit. Put a small pin inside and press and hold the pin for 30sec.  If there is no pin hole then press the power button for 12sec. Remember to remove your charger when you do that.
