David, is the cpu in dell 5421 can be upgraded? and how to find suitable upgrade?
the CPU can not upgrade, it was soldering on the motherboard
thank you for your answer.. 😀
The screw that secures the DVD drive is incorrectly marked. The correct screw is left and slight up from the one you marked. Unfortunately, I broke off the DVD drive cover while attempting to remove it, now I have to buy a replacement. 🙁
I appreciate the instructions you provided, but I am hoping the rest of the instructions are correct.
The DVD Screw is correctly marked, i have this model.
Can this model hold an ssd drive and keep the original HD for storage.
Good morning, I need to improve the performance of my dell Dell Inspiron 14R 5421, I noticed in the previous answers that the processor cannot be improved. Do I need to know if I can improve RAM? Currently, it is 4 GB and a single channel.
