I seem to be the first person ever to do this. I love the machine, but spilling cheap beer all over it has not made things better. But you probably got here due to the following terms: hp envy ultrabook beats 14 model 4-1038nr cover case bottom disassemble remove open screws damn feet drive battery spare replace remove hell instructions guide howto RAM memory HDD SSD hybrid … So here’s what you came for.
There are only 12 screws to take out. All on the bottom, yes you must take all 12 out. None of them are special, no hinge-clutch-anchor Jesus screw. No, you do not need to remove the feet. No special tools required, I pried the case edges with the back edge of the world’s cheapest tweezers. You can do it with a dime. I fiddled and cajoled a starting point for prying it open on the corner close to the network port.
There are FOUR screws holding the drive cage in place. The fourth is under the battery.
The battery is held down by three screws, but one of those feels and works like a captive screw. That is, you can get it backed out far enough to remove the battery, but good luck removing the screw itself. No prob. The battery comes right out anyway.
The hard drive cage is actually two rails along the edges of a heavy foil sheet. Careful. You’ll probably need to take the “cage” off if you need to plug the standard SATA connector drive into anything.
So my keyboards (built-in and USB for troubleshooting) and hard drive are not seen by the system during boot, although later it will see kb hits. But by then it’s only accepting “any key” in order to try to boot again. No dice.
Time will tell if I get my machine running again. I did however want to share the particulars of disassembly. Hard-won knowledge.
Update. Bought another, merged best parts, learned that the hybrid drive is a RAID (which recovered itself gracefully, thank heavens), and now I have a laptop I love with all my data and apps, twice the RAM, and a spare case. You know. If I ever needed one.
