I have this same 3521 laptop. I bought it new in 2013. I put in a 1tb ssd and 8gb of memory and microsoft will give you a free upgrade to windows 10 for free. My fan is making noise so I sought out this video (this is 11-14-2022) and i appreciate your work here. Thank you.
Glad I watched. In the disassembly I saw the answer to my question. My 3.5mm jack is bad and it looks like a MoBo replacement is in my future. Thank you!
Thanks for the nice video. I liked it as you give the commentary. My Dell 3521 fan is running more than normal under high CPU usage. I used the video to check the fan and heat sink for dust. No dust was found so I changed the thermal paste on the CPU and hope it solves the issue.
I got this i5 3777u version in 2012. Still working well after 3 critic falls, only HDD died from shock. I replaced it with an ssd and upgraded ram 4 to 8.
hahahhaa... that knife made so many marks...you should use plastic tools for that. But thanks anyway I got the information I needed to uncover same model. Thanks!
Actually the knife don't have sharp edges. I use a metal tool for more than 10 years, and no marks so far. If you know what you are doing, you can use a metal tool also. I use and plastic, but the metal one is more durable.

dude how did you upgrade it to 8gb ram i tried to do that but when i turn on my pc he do some bip sound
@@ShinraOkami I have this laptop as well and was able to upgrade my RAM to 8 (also changed to SSD)
How was it changing to SSD. I upgraded the ram on my from 4gb to 8gb but clock speed on cpu is still slow.
Clock speed has nothing to do with the memory. Only way is to clone the os on a SSD drive and the laptop will start to work faster.
How do you clone this? Thanks
I have this model of laptops.
How old is your PC and it's still working?
It is a costumers laptop, not mine. Yes it is still working, it was in the office just for cleaning.
