❓ Help Lenovo Thinkpad L480 No Display

[Chicharongbaboy]

Anong possible issue nito mga bossing?

With power, no display. May ilaw ang Capslock, Fnlock, at power button (pero not responding, steady light lang). Working ang fan. No beep sound. (POST error)

Tried:

• reseating RAM (nilinisan kona ren)
• gumamit ng working na ram
• unplugged battery and cmos and holding power button while unplugged (walang reset pin)
• win + ctrl + shift + b

No luck. No display paren.

Mukhang No POST / Motherboard Failure na 'yan boss.
Yung "steady light" at "not responding" na CapsLock ang giveaway. Ibig sabihin, frozen ang system board at hindi nagpo-process. Hindi lang siya simpleng display/screen issue.
Most Likely Causes:
1. Corrupted BIOS: (Pinaka-common sa ganyang symptoms). Need na i-reflash gamit ang hardware programmer.
2. Dead GPU or Northbridge: Hardware failure na sa board.
Try mo Isalpak sa External Monitor (HDMI/VGA). Kapag wala pa ring display, confirmed na board-level repair na ang kailangan niyan. Dalhin mo na boss sa technician.
