What is the slot to the left of the mSATA slot on the HP EliteBook 8770w?
Here's a photo of the inside of my HP EliteBook 8770w:
Check out the slot where I put the three red question marks — what's it for? The gold connectors at the top look remarkably similar to the gold connectors at the top of the mSATA slot, but I don't think that the laptop supports two mSATA drives, although I could be wrong about that. Anyone know for sure what that slot is for? Thanks much, Joe
If yes then looks like there is a second mSATA drive already installed in your laptop. And BIOS presents it on a hardware level as as part of first mSATA drive. This was done to manage a bigger storage at the early stage as the SSD drive capacity was not so big.
