STEP 2.

Under the cover you’ll get an access to both memory modules/slots, hard drive, wireless card and CMOS battery.

Also, some Dell Studio 1555 models can be equipped with WWAN and WPAN cards.

Remove four screws securing the hard drive. Slide the hard drive to the right to disconnect it from the motherboard.

STEP 3.

Lift up and remove the hard drive.

If you replacing the hard drive, you’ll have to transfer mounting brackets to the new drive.

My Dell Studio 1555 laptop has a regular 2.5″ SATA hard drive which can be upgraded to a SSD hard drive (expensive but

quite and fast).

STEP 4.

In order to release the memory module you’ll have to spread latches on both sides of the memory slot.

The memory module will pop up at a 30 degree angle.

Pull both memory modules from slots.

Dell Studio 1555 laptop uses DDR2 PC2-6400 memory. It can take up to 8GB total (up to 4GB RAM in each slot).

If you want to use more than 4GB RAM, you’ll have to run a 64-bit operating system.

STEP 5.

Remove one screw securing the center control cover.

STEP 8.

Remove two screws securing the keyboard.

STEP 9.

Lift up the keyboard and place it upside down on the palm rest.

Be careful. The keyboard still attached to the motherboard. There are two ribbon cables running from the keyboard to the

motherboard.

Before you can remove the keyboard, it’s necessary to unlock both connectors and release cables.

STEP 10.

You can unlock both connectors using the same method.

Lift up the right side of the locking tab. It will open up at a 90 degree angle.

STEP 11.

On the following picture the connector shown in the unlocked position.

Now you can pull the cable from the connector.

Open up another connector using same method.

STEP 12.

Remove the keyboard.

Now you can replace it with a new keyboard if needed.

STEP 13.

Disconnect both antenna cables from the wireless card.

If you have WWAN and WPAN cards installed, disconnect antenna cables from them too.

I would suggest making notes how those cables are connected.

STEP 14.

Unroute all antenna cables.

Remove two screws securing display hinges on the bottom of the laptop.

STEP 15.

STEP 23.

STEP 24.

Lift up the front side of the CD/DVD optical drive and disconnect it from the motherboard.

STEP 25.

Remove four screws securing the ExpressCard board.


13 of 20 21/11/2011 12:53 PM

STEP 27.

Remove the ExpressCard board.

As you noticed, I disconnected cables from the card itself and left them connected to the motherboard.

Remove six screws securing the motherboard.

Disconnect three shown cables from the motherboard.

STEP 29.

Lift up the right side of the motherboard and carefully pull it from the bottom case.

STEP 30.

Remove the motherboard.


15 of 20 21/11/2011 12:53 PM

STEP 31.

On the bottom side of the motherboard you’ll get an access to the cooling module (cooling fan and heat sink).

If the cooling fan and heat sink look dusty, you can blow it off with compressed air.

Also, cleaning the cooling module will fix any possible laptop overheating issues.

Noisy fan? New Dell Studio 1555 fans available here.

STEP 32.

If you would like to replace the cooling module or apply new thermal grease on the CPU, you’ll have to remove it.

Loosen six screws securing the cooling module and disconnect the cooling fan cable from the motherboard.

Now you can separate the cooling module from the motherboard and access the CPU.


16 of 20 21/11/2011 12:53 PM

STEP 33.

The DC jack (power connector) in Dell Studio 1555 laptop is not soldered to the motherboard.

The DC jack attached to the power harness which can be unplugged from the motherboard (we did it in the step 28).

If your DC jack failed, just replace the entire DC jack harness.

It’s possible this guide will work for some other Dell Studio laptops. If it works for you, please mention the model in

@Jay My Studio 1555 has an overheating issue with the GPU and therefore would like to investigate the cooling

system on it. As this appears to be a lengthy process to take apart I’ll dedicate a few hours on Saturday and post back

how I get on and what parts I didn’t have to disassemble.

If anyone has some hints or tips before I get to work I’d really appreciate them. Thanks for the guide, very detailed

apart from mentioning the graphics card (I assume your machine has the integrated one?).

Hi. This is a very thorough guide but is it possible to get an access to the video card without removing LCD or taking

out the motherboard?

I have to replace the power button cable. To what degree of disassembly do I need to do to accomplish this? I think the

cable I bought has a wifi connection as well. Great detail by the way. Fantastic help.
