Thanks so much for this guide. I’d found my PC’s manual/repair guide online (it’s an HP 15-r011dx) but the instructions were much more cumbersome. Your guide is excellent, and now with twice the RAM, I feel like I have a totally different PC!

The whole upgrade was much more fidgety though than any Mac I’ve ever worked on, and so strange that HP puts the RAM chip on the motherboard. Crazy… It’s like having to do a root canal to brush your teeth!

I used this guide to upgrade the memory on an HP 15-r011dx, and found that the keyboard ribbon is very finicky. In fact, the first time I put the PC back together, many of the keys on the keyboard didn’t work! Two more tries did the trick. I finally realized that the teeny, tiny teeth on the ribbon must be carefully threaded into the connector (i.e., lined up exactly in each tiny track) in order for the keyboard to work. I usually work on Macs and have never encountered this issue before now, but next time I take apart this, or any other PC laptop, I’ll know this is a quirk.

OMG!!! The rating for this repair as "moderate" is waaaaaayyyy off! I've been repairing various laptops for YEARS on iFixit and this was my first attempt at a desktop repair. It was so much more fidgety and difficult than the hardest laptop I've done (probably about 12 - 15 other repairs by now).

And sorry... tho' I love this site and am grateful for these tutorials, this one was wanting in detail and assumed that I not only knew terminology that I didn't know (I was able to figure it out of course, I DID finish the repair) but skipped important details that made it infinitely harder (and took me waaaayyy longer than it should have!). For example, when removing the optical drive, the guide skipped about three steps and I ended up accidentally breaking some delicate plastic bits. And gee thanks for waiting until I have everything apart to tell me I need a longer screwdriver! I found a tedious workaround, but... sheesh dude! All in all, I'd have to say...by far the WORST experience I've had on this site!
