Replacing Compaq 615 hard drive with a SSD

This is a HOWTO instruction for replacing a spinning platter hard drive with a modern faster solid-state drive. Since Compaq 615 has Windows 7 Home Premium OEM installed, I'll blog about the Windows Activation in more detail on my next post.

This kind of Compaq laptop is quite generic PC. Majority of this information applies to almost any laptops I've disassembled. It's about the location of the drive, location and number of screws, but the information in general covers the operation of replacing a drive with another one.

I started this project with checking for Manuals for Compaq 615 Notebook PC @ HP. The good stuff is at PDF-document with title Compaq 615 Notebook PC and Compaq 610 Notebook PC - Maintenance and Service Guide.

It will contain all the information a service technician would need to successfully operate on this kind of hardware. On page 4-8 it has the hard drive replacement procedure documented.

Anyway, this is something I've done a lot. I briefly checked out the location of the drive and the screws that needed un-screwing. Here is a pic from the flipside of the laptop:

Those two screws hold a HDD-cover in place. The screws even have a HDD-symbol next to them. Un-screw both of them with a small Phillips head screwdriver:

Remove the HDD-cover by pulling up from the side you removed the screws from. The drive is visible:

The drive is held in place by a single Phillips head screw. Remove that too. Pull up from the drive screw bracket and the drive will slide left and reveal a standard S-ATA -connector:

Now you have the drive completely detached from the laptop. The actual hard drive is connected to a metal cradle with 4 Phillips head screws. Un-screw them:

As you can see, the screws are really small. The screws are quite tight, see the blue substance in the screws. It is threadlocker and its purpose is to make sure a screw is tightly attached. If you don't have the proper sized screwdriver, you will destroy the notches of these screws making removal really difficult. This is the only part of disassembly, where I needed to apply some force just to make sure that the screwdriver wouldn't slip.

The next step is to attach the new SSD-drive to the cradle:

Think really carefully which way the drive needs to be attached to the cradle. There are four possible options, but only one of them will yield success. You will see quite soon the position the cradle needs to be in the laptop. The hard part is to figure out which way the drive needs to be to succesfully connect to the S-ATA -connector of the laptop.

When the hard part is done, all you need to do is slide the cradle back to S-ATA connector and secure the screw holding the cradle at place. Then put the HDD-cover back and secure the two screws for the cover.

All this will take around 10 minutes on experienced hands. If this is your first laptop maintenance work, reserve a hour. Nothing here requires much force to be applied. If you are applying much force, you're doing something wrong.

Good luck on your project!
