Asus VivoBook X407MA | No display but with Power

[juandelacruz2008]

Hello mga boss! Pa-help naman po kasi yung Asus VivoBook X407MA after i-upgrade yung RAM, ayaw na mag-display. Pero pag tinu-turn on ko, umiilaw naman yung power.

Na-try ko na:

• To turn on without battery (direct from charger) - both lights po meron (red for the battery, white for the power indicator)
• Turn on with battery only - power light is on (power indicator)
• Turn on with battery while charger is plugged in - both lights meron (white for battery, white for power indicator)
• Binalik ko na rin yung old RAM, pero wala pa rin talagang display

Notes:

• I have checked the LCD display cable and intact pa rin naman sya. Hindi ko inalis yung sticker kaya hindi nagalaw.
• Fan is not spinning kahit naka-on yung mga lights
• No display talaga kahit yung POST or logo ng Asus di talaga lumalabas

Baka po may makatulong. Maraming salamat po!

[ UPDATE ]​

Okay na po itong request ko. Pwede na po i-close. Hehe

For future reference and para sa ibang makaka-encounter ng similar problem, I performed the following to repair the laptop:

• Reapply Thermal Paste
• Cleaned the RAM contacts with an eraser
• Disconnect then reconnect all flex cables (display, keyboard, touchpad, fingerprint)
• Reset the BIOS by removing the battery and charger then pressing the power button for at least 60 seconds

Actually I'm not sure which of those repaired the laptop. Nilista ko lang para magka-idea yung iba kung paano mag troubleshoot and repair. Hehe

Thank you mga ka-symb!
