HP Envy 17-X108CA

[mon2]

Hi. Have a 17" HP laptop (17-X108CA) with no video/POST due to liquid damage (wine spill). Have removed all mating cables except LVDS & fan & power in. Fan turns on; no video; no beeps; screen is dark.

Do not have the schematics. Would anyone have this schematic?

In checking the assorted power rails, found a switching regulator:

aoz5029qi-5

that does not appear to be working.

Would anyone have a schematic (datasheet would be even better) for this EOL component? Found that it is used on the ACER laptop as well.

Re: HP Envy 17-X108CA

hi. please see attached. does this help to identify the motherboard?

welcome all ideas.

BTW - the above switcher has been superceded with AOZ5048QI. A drop in replacement but improved and available from Digikey. Arrived today and replaced but fails to bring up one of the power rails which is stuck @ 0.9mV (millivolts). Will try to reflow the fresh device again.

The computer has had wine spilled on it but we have done our best to clean it up. The fan does spin and many rails including 1v2, 3v3, 5v1 are coming in with the supplied 19.xx volt DC in power adapter.

The screen and backlight are dark - no boot chime / beep. Did attempt an external HDMI monitor but it was also dark - not sure if we pressed the external monitor enable key sequence - the keyboard feels crunchy.
