Replacing, removing, upgrading RAM or memory on Dell Latitude E5520 i5 latop. 

I know I am a bit late to the club, but thanks for the heads up! As my dad's laptop is breaking apart, I dusted off my own old E5520 I had laying around, added a second 4 GB RAM stick into it (already had a 128GB SSD, which was big when it was built in). He really doesnt need a 1000 € gaming laptop, so its still totally fine for him. I also replaced the CMOS battery. If anybody is interested, you can buy used batteries online for cheap or refurbished ones for really expensive money. In the end its just a normal 2032 button cell, the same as you put onto any other mainboard. Just cut away the shrink wrap, remove the contacts from the battery with a sharp razor and then tape them down on a new cell with some Gaffer tape. Works like a charm!

I am still using this laptop in 2019............. pretty frustrated with its performance this was a decent tutorial thanks.......

Thanks for the demonstration. I used to to assist in replacing a hard drive. Very straightforward.

Very helpful, exactly what I needed. My E5530 only had two screws holding that plate though. Thanks!

brilliant thank you very much so helpfull

I haven't tried it but rumour has it 16gb will work. Try this at your own risk though!

Thanks for the great tutorial. It made my upgrade very easy.

Glad to hear it! I've fitted a Vertex 3 Solidstate drive to my wife;s and it boots up in under 10 seconds, I would definately recommend solid state drives.

I bought a loaded refurb last March and the Hard Drive was bad. Now that the new Hard drive is in, this pc flys with I7 and 8gig RAM

Hi, can i put one memory of 8gb? In my PC one slot ( slot b) Is broken. I need upgrate to 8 GB, but i can not install two memories of 4gb.

i have a Dell Latitude E5420. My computer wont show the second drive in My Computer. It is detected in the BIOS and shown as incompatible in Intel Rapid Storage Technology.

Sorry for late reply, It shoudn't matter but the Dell only supports 8gb so officically you can only run 2 x 4 gb (4 in each slot)

by the looks of things can you put a M SATA SSD right? also can you upgrade the RAM to 16GB 1600Mhz or 1866? and is the CPU upgrade-able to the i7 3520m processor?

Do you also have a Video resetting the BIOS ?

Thanks man, the video is great it helps...

Is there a way to safely replace the thermal paste?

Do you know what the card slot between the RAM and the Wireless card is for ? Looks like another wireless card slot to me.Got the back off mine and just notices it sitting there empty.The bay to the left of the wireless card is for a WWAN card from what I can find out. Is this correct ?

I unable to find a service manual outlining how to replace the CMOS battery.

Hi thanks for your video...

if you could help me...how do i remove the cmos battery?

Your welcome, glad it was of some use.

I'm glad it was of some help.

This dell laptop (as far as I know) will only support a maximum of 2 x 4gb. This is due to intel chipset for this particular board

How can I activate SIM contact?

Does it have to be a particular brand of RAM? Only original Dell?

Great tutorial! I replaced the 2X2gb with 2X4gb - computer booted up fine but when I go to my comp>properties I see 8Gb(3.16 Gb usable) - hmmm - suggestions? thanks :-)

Glad it was of some help.

Your welcome

You're welcome

To ADD to this...NEVER do this on your CARPET FLOOR A computers worst enemy is STATIC ;)

2 x 8GB..??

Thank you.

Sorry for late reply, I'm afraid I cant really help you, it depends on so many factors.

thanks !

Your welcome
