These instructions explain how to take apart a Sony Vaio VGN-FZ220 series laptop.
I had to replace the DC-IN power jack because it was broken. The jack is soldered to the power harness and can be easily replaced if you have basic soldering skills. Use this guide on your own risk.
I will be taking apart a Sony Vaio VGN-FV220E model but I think you can use them for entire VGN-FV220 line.
Unplug the power adapter. Unlock and remove the battery.
Remove one screw securing the memory cover and remove the cover.
Remove one screw securing the hard drive cover and remove the cover.
Remove three screws securing the hard drive. Slide the hard drive to the left side and disconnect it from the connector on the motherboard. Remove the hard drive.
Remove both memory modules (spread latches on both side of the slot and carefully pull the module out).
Remove two screws securing the DVD drive. Carefully pull the DVD drive out and remove it.
Remove all screws (marked red and green) from the bottom.
If you are taking apart the whole laptop, you’ll have to remove all screws.
If you are using this guide just for removing or replacing the keyboard, you’ll have to remove just four green screws (they secure the keyboard bezel) and after that you can proceed to the steps 7-9.
Carefully disengaged three latches in the battery compartment. These latches secure the keyboard bezel. Push on latches with a small flathead screwdriver until they are unlocked.
Unlock two more latches in the DVD drive compartment. I wasn’t careful enough and broke one latch.
You can remove the bezel with a small flathead screwdriver.
Remove two screws securing the keyboard.
Carefully lift up the keyboard and place it upside down on the palm rest. The keyboard cable is connected to the motherboard.
First, unlock the connector. Remove clear tape securing the connector. After that slide the LOCK (this part of the connector secures the cable inside) about 1-2 millimeters to the left using your fingernails. This will release the cable. Now you can pull cable from the connector and remove the keyboard.
WARNING! If you break the connector the keyboard will never work again (unless you find a way to repair the connector or replace the whole motherboard). Be careful.
Disconnect cables pointed with red arrows.
Disconnect three wireless card antenna cables pointed with yellow arrows.
Release all disconnected cables. Remove screws securing the display hinges (three screws securing each hinge).
Lift up and remove the display panel.
IMPORTANT! You’ll have to go through steps 10-12 only if you want to remove the display panel.
In order to remove the laptop base cover and access the power jack, it’s not necessary to remove the display panel. I understood that only after I removed the display.
Here’s what you have to do. Leave all cables mentioned in the step 10 connected and go to the step 11. Remove only two red screws from each hinge and do not remove green screws. Now you can close the display and proceed to the step 14 (removing base assembly).
The display panel has been removed. I didn’t have to remove it but I did.
Turn the computer upside down and remove the base cover.
Now you can access and replace the DC-IN power jack located in the top left corner.
Do you see the RTC (CMOS) battery? I’ll explain at the end why I mentioned the battery.
The DC-IN power jack was broken in many pieces. I unsoldered the broken jack and replaced it with a new one.
The power jack has been replaced. Now you can assemble the laptop following steps 16-1.
IMPORTANT! After I replaced the jack, I assembled the laptop back together, plugged in the power adapter, pressed on the power button and NOTHING! The laptop was dead! There were no LED lights or any activity at all. I tested power jack continuity with a voltmeter and didn’t find any problem. The motherboard was getting power but didn’t turn on. I thought the motherboard was fried. Just in case I unplugged the RTC (CMOS) battery from the motherboard, waited for 30 seconds and plugged it back in. Tested the laptop again AND it started like new!!!!
