This article covers the SSD and RAM Upgrade of my HP 15-ay045ng (X5Z22EA) Disassembly. Here are the exact specifications, but it might also apply to other models of this series.
Model: HP 15-ay045ng (X5Z22EA)
CPU: Intel Core i3-5005U (2GHz, 3MB Cache, 2 Cores)
GPU: Intel HD 5500 Graphics Card
Memory: 4GB DDR3L-1600-SDRAM

Find all details here and a notebook test here.
I upgraded the existing M.2 SATA SSD with 128GB to a 256GB M.2 SATA SSD because I needed more storage. I also added some additional memory (RAM) because I had one some DDR3L-SDRAM in stock.


To make the upgrade really easy and simple, you should clone your current SSD to the new one. Find here the guide.

Disassembly and Parts

At first please remove the battery, this is still a model with a battery which can be removed and replaced easily 🙂 After removing all the screws, it was quite tricky to remove the backcover since there were some additional hidden screws, check the picture below. If you have removed all screws from the backcover, simply use a plastic card or some plastic disassembly tool which will help you in this step.

If you know how to open the backcover and the hidden screws the process is very simple and I highly recommend you to upgrade if you need more storage as the device is really great for the price. I can definitely recommend this laptop because cost-benefit ratio is simply amazing.
