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 andfast).

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.

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.

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 comments below.

@ Charlie,

What do you think can be the issue and did I make the right move not to have any parts out in?

It looks like your laptop has multiple problems. I’ve seen it happening before many times and laptops like that are very hard to

troubleshoot and quote repair correctly.

Definitely that was the right move! Laptops like that not worth fixing. It’s better to buy a new one with new hardware andwarranty.

Great guide. In having issues of it overheating then shutting down. I brought it in for a diagnostic as they first told me that I wouldneed to replace the fan and the hardrive. Then they call back after getting the parts and tell me I need to also replace the

motherboard. They quoted me $180 for a reconditioned fan, a new hardrive and labor. I was cool with that, but they told me areconditioned motherboard could cost over $500. I told put it back the way I gave it to them. I could buy a new computer for that

amount.What do you think can be the issue and did I make the right move not to have any parts out in?

Great guide. My power supply is dead – no voltage ant the plug but the blue LED in the plug lights (?!). Is there a fuse after theLED but before the plug in the molded plug itself?

@ ruben,

Try removing memory modules one by one. Test the laptop with each memory module separately. Maybe one of the modules isbad.

Thanks so much for this guide, was really helpful in dissembling my broken studio 1555.My three year warranty on it ended 5 months ago however last week i realised I couldnt turn my studio on anymore…..whether

on battery or cable only, the system wont start at all when i press the power button. I’ve tried a hard reset and now dissemblingthe laptop and putting it back together but neither seemed to help. The hinges of my LCD screen are cracked/dodgy but other than

that theres nothing visibly wrong with it. In the weeks leading up to its failure to turn on, it crashed a number of times when i wasgaming im assuming due to massive overheating.

Has anyone else encountered this problem of not being able to switch on their dell studio 1555 ? or maybe know a reason as towhy this has occured?

Any assistance would be great.

EDIT: After I reassembled my laptop, it miraculously turned on!!!!!!!!!!!!!!! howeveer i didnt have the hardrive in so had to turn it

off – only way to power it off was to remove the battery as the power button stopped responding after it booted. Now I cannotturn the laptop back on ….. messing with my head.

I know it has nothing to do with the hardrive as I’ve booted it on my desktop, however is it fair to say from this that there is a

problem with the power button? (maybe its worth replacing the power button?)

Thanks so much for the photo guide! my laptop’s been broken for about 3 months (screen wont show anything on startup), and i

reckoned i could fix it myself if i found a guide to take it apart with. This guide led me to find that a loose LCD display cable wasthe culprit. Thanks so much!

@ Carl,

I recently picked up a 1555 so this has been very helpful.

It’s a bad way…no output to the LCD screen but is OK via separate monitor.

Most likely it’s either failed LCD screen or failed video cable.

Off topic I know but I didn’t get any driver or utilities discs with this machine, but have been offered some from a1558 model would this be OK to use for the 1555?

All drivers and utilities should be available for download from the Dell website.

Dell won’t supply me any OEM ones as I didn’t purchase the machine.
