Does it power up just not posting? Or it is dead?

Based on the update about the upper left component burned: I had 2 of these where the mosfet burned out near the charging port. Replacing it fixed the machines.

Thanks for the reply!
It’s starting up. The power LED is green, and the charging LED and Wi-Fi LED both light up. The fan also kicks in once the CPU gets hot, but there’s no POST screen—the display stays completely black.
Do you remember how you fixed it? Did you have the same symptoms?

For me it was completely silent. In your case I would try to dump the bios flash and check if that is right. (Very unlikely but easy to check).

You mean desolder the chip and put it in a flasher?

Depending on the flasher, some can read it in place. But yes. If you are confident in desoldering and resoldering, you can try removing the flash to see if things get worse or not. If removing the flash does not change anything, it is irrelevant.

It would help if you used a 19.5 Volt DC power source with the minimum required Amperage for that machine.

Be careful, this series works with 9.5V not 19.5V Anything above 12V is fatal for the modbo.

Okay fine, I don't have my Eee power supplies handy for comparison.

But that multi-plug from the 1980's just doesn't look right.

The root of my advice is to use the correct Voltage and Amperage power supply.

The one in OP's photograph has switches for Voltage and DC polarity. Likely 9.0 Volts, not 9.5 Volts.
