ASUS ZenPad S 8.0 Motherboard Replacement

Be very careful when prying apart the back case. I was very cautious but still managed to slightly warp the silver bezel at one location, so after reassembly I have one small section of this bezel that won’t snap completely flush with the back case. That said, opening this tablet is surprisingly easy.

I removed both ribbon ends on the ASUS-labelled ends of the cable. FWIW, one of my connector lock tabs is white & the other is black.

In my case (a Z580CA instead of the Z580C pictured) one of the lock tabs was white and the other black, as the previous comment noted, but also the printing on the ribbon cables is slightly different (i.e. the white ribbon cable had “ASUS” printed on its left end, instead of what’s pictured above). What seems more consistent among models is the ID printed on either end of each ribbon cable:

Top (white) cable: “SB” or “FPC_SB” ⟧≣≣≣≣⟦ “MB” or “FPC_MB”

Bottom (orange) cable: “LCM” ⟧≣≣≣≣⟦ “MB”

So, all in all, I agree with the previous comment — it’s enough if you remove the connectors on the “MB” end only.

Bottom line cable holder colors were inverted. I destroyed my tablet because I followed “pry open white part”. :-(

The tray only provides a mounting location for the battery which is securely stuck to the tray with foam tape. Pry them gently apart. I reinstalled my tray & screws, then reconnected the power cable and finally placed the battery into the tray. The clone battery is physically smaller than the original and the power cable isn’t in quite the same place but it does fit.

In my case I did remove the metal tray as I found it easier to pull the battery away once I had the tray in my hand. But if you know approximately where to insert a plastic tool to help separate the tape, I fully agree that removing the metal tray is completely unnecessary. FWIW, in my case I had two strips of double-sided tape, running vertically (considering the orientation of the picture above), one of them approximately at the level of the screw in the 11-o’clock position, the other approximately at the level of the 5-o’clock screw.

Also, my tablet (Z580CA) had only eight screws (weird — the one at the 3-o’clock position was missing) and I found them to more closely match a 2.0mm screwdriver head.

The battery part number shown in one of the pictures and what is in my tablet is C11Pn9H. I ordered a Cameron Sino C11P1304 from Amazon that states it’s compatible with a C11Pn9H. It really is not. It’s smaller and the power conector is 1/4” inch away from the corner. I’m sending it back.

I found and ordered on Amazon a DGTECH C11P1510 battery that also states it’s a compatible battery for the Asus ZenPad S 8.0 Z580C Z580CA Z380C Z380C and looks exactly the same as the C11Pn9H but it costs more. $39.99 compared to the Cameron Sino for $23.89. Ouch! almost double the price. Also 1 Year Replacement Warranty as the Cameron Sino battery.
