I’ve just successfully replaced the hard disk in my Acer Aspire V15 V3-574 with a new SSD. This thread is about the closest I can find with instructions on how to do it, but I haven’t found anywhere a good resource for this particular model (and presumably other models based on the Aspire V15). So I’ve written up a little guide below with some photos, hopefully this will be helpful to others.
Step 1 – Flip the laptop over and remove the 17 screws circled in red in fig. 2
Step 2 – Remove the screw holding in the DVD drive (circled blue in fig. 2), then slide out the DVD drive to reveal 3 further screws.
Step 3 – Remove the 3 screws under the DVD drive, circled in green in fig. 4
Step 4 – Turn the laptop the right way up and fully open the screen. Using something thin and plastic (I used a kid’s glue spreader – see fig. 5 http

/www.hobbycraft.co.uk/glue-spreaders-5-pack/582522-1000) start from the front and prise up the silver panel. Work around the two sides until you reach the back
Step 5 – Close the screen and turn the laptop back upside down. Using the plastic tool prise apart the back edge around the screen. Be careful not to let the two pieces of casing suddenly pull apart as there is a very thin wire connecting them.
Step 6 – Once the bottom part of the casing is fully unclipped, tilt it up from the back edge (where the screen hinges are) as in fig. 6. You will see that the small wire connecting the case to the motherboard labelled in fig. 7. It is possible for this wire to be unclipped and the case fully removed. However the connector (fig. 8) is quite tight. I decided to leave it clipped in and propped the case up using a box. You can still get full access to the inside without unclipping this wire.
Step 7 – To remove the hard drive, simply lift from the outside edge and slide away from the connector (fig. 9). There are no screws or clips holding the hard drive in place. The hard drive is in a small “caddy” made up of two rubber strips and a thin transparent plastic sheet (fig 10). The two rubber strips fold outwards from the hard drive.
Step 8 – Insert your new drive into the caddy. The SSD I bought was thinner than the original hard drive, so I attached the stick-on plastic frame that came supplied with the new drive to make it thicker (fig. 11). Re-insert the drive into the laptop.
Step 9 – At this point it is best to check that everything works, because reassembling the case is a bit tricky and you only want to do it once. Fold the back case down and let it sit loosely over the motherboard. Flip the laptop the right way up and turn it on. Make sure everything boots up properly. If it doesn’t you’ll have to look elsewhere on the net for help as it could be many different things! (Although see my notes below first).
Step 10 – Reassemble. I found this more tricky than disassembly. Start from the back hinge, then flip the laptop and work around. Make sure all of the ports / connectors are correctly placed in the casing holes. As there are USB sockets on both sides of the case, it can be a bit tricky getting the case to fit back over the top (fig. 12)
Step 11 – Put in the three screws in the DVD tray area, slide in the DVD drive and put back the 17 case screws and the 1 DVD drive screw. Good practice is to get all of the screws in “finger tight” then go back and tighten them all up at the end. Job done.
Notes:
I had a few issues doing this which you may or may not also have:
(1) When I first installed the new SSD, the computer turned on but didn’t boot up. I replaced the old HDD to confirm I hadn’t broken anything (which I hadn’t) and got Windows loaded up. The issue was that before cloning my HDD, I formatted the new SSD in Windows, where it was assigned the drive letter E. I guess this was sticking and so the laptop wouldn’t boot. To solve, I reconnected the new SSD via a USB enclosure, opened the Windows 10 computer management app and went to “Disk management”. The main partition of the cloned SSD was again showing drive letter “E”. By right clicking on the partition, you can remove the drive letter so that the disk is unassigned. I re-installed the SSD in the laptop and it booted fine.
(2) During reassembly I really struggled to get the case seated over the front left corner of the laptop (where the audio jack is). This was due to a thin bit of plastic left over from the injection moulding blocking the jack hole. Using a craft knife I carefully removed this bit of plastic to fully open up the hole, which helped the casing seat nicely.
(3) The first boot after reassembly I noticed that the DVD drive had disappeared. Fortunately it reappeared after a restart!!
