Dell Vostro 3550 CMOS Battery Replacement
Introduction
Go to step 1This guide will explain in detail how to replace the CMOS battery in the Dell Vostro 3550. An easy way to tell whether the CMOS battery on your device needs to be changed is if your computer suddenly forgets the current day and time.
What you need
-
-
Turn the laptop right side up. Open the display to reveal the keyboard.
-
Use the metal spudger to pry the keyboard upward from the base. Make sure to pop each of the three clips keeping the keyboard in place.
-
-
-
Pull the ribbon cable away from the connector.
-
Remove the keyboard.
Do not pry the base. This will deform the aluminium keyboard base.
Release the clips at the top of the keyboard, 4 of them, not 3. Gently pry the top as you release each clip. The keyboard will lift towards you from the top.
Do you even do this or do you just offer an opinion?
FFS.
I followed the steps outlined in this repair guide and I had no issues at all. Do you think the issue is that you are not mechanically inclined? If you deformed your keyboard base that is a shame. FFS

Remove the small cable connected to the left side of the casing.
-
Repeat this step for the three remaining cables on the casing.
-
-
-
Remove the two 5mm Phillips #0 screws to the far right and far left of the motherboard casing.
There are four screws on this bracket that need to be removed.

-
Using the metal spudger, pry the palmrest assembly from the lower case.
-
Lift off the palmrest assembly to reveal the motherboard.
It took me a good 20 minutes to figure this out but there’s a screw that has been skipped over here in the bottom left corner. Underneath one of the rubber bits.
Sorry! It took us a very long time to figure this out too. Not sure if we had a screw there or was missing.
This wasn’t easy. I had to unscrew most of the screws from the bottom of the laptop to get this piece off. After this, Finding the battery and replacing it was the easy part
Well I also managed to do it and it worked. Must say, I had to unscrew ALL the screws on the back of the laptop to be able to get to the CR2032 battery.
This has to be one of the worst guides I've read on here. You need to remove ALL the screws on the back of the device to remove the top panel.

Thank you, this saved my day.
Two small things:
- In step 7 I needed to remove four screws (visible in the picture).
- In order to perform step 9, I needed to remove seven screws from the bottom case.
Glad you found it helpful!
Note: before step 9, we need to remove all the screws from bottom before open the cover!
Thanks for all, it´s helped me A LOT!!!!!
What size is the battery? Does it have a pigtail?
