Dear Melroy,
Thanks for your message! This guide refers to the SCPH-900xx models, your model is a SCPH-7700x model so it‘s no wonder that it differs. Unfortunately there isn’t a separate page for that model yet but feel free to create a specific model page and add some useful manuals.
Greetings
MrJulian

Simple and easy to follow. I really do miss how straightforward it used to be to take apart game consoles.
Everything is okay but how I can extract drive?

I opened up my slim silver ps2 scph-90001, can't find the cmos battery anywhere. It's not under the fan, it's not under the motherboard. This is the American silver version. I have the replacement battery I just don't know where to put it.
Hey Cory,
The PS2 shown in the guide is a European model (SCPH-90004) which has a CMOS battery. The guide mentions that other region models may not have a clock battery which could be the case on 01 models (Northern America).
