In this guide I explain how to take apart a Dell Studio 1537 laptop.
I think this guide might work for all laptops in Dell Studio 15 model line. If it works for you, please mention the model number in comments after this post.
I will cover the following disassembly steps:
1. Removing laptop memory and hard drive. Steps 1-7.
2. Remove laptop fan assembly which includes the cooling fan and heatsink. Steps 8-12.
3. Cleaning the heatsink assembly and and taking apart the cooling fan. Step 13-14.
4. Removing and replacing laptop keyboard. Steps 15-21.
Before you start, make sure the laptop is turned off.
Remove seven screws securing the bottom cover.
Lift up and remove the bottom cover.
When the bottom cover is removed you can access the hard drive, wireless card, both memory modules, CMOS battery and fan assembly.
Remove four screws securing the hard drive.
Disconnect the hard drive cable from the motherboard.
In order to disconnect the hard drive cable, simply lift it up by the blue tab.
Remove the hard drive assembly.
Remove four screws securing the hard drive to caddy.
Disconnect the hard drive cable.
Now you can replace the hard drive with a new one if needed. It’s a regular 2.5″ notebook SATA hard drive.
Both memory modules located under the same bottom cover.
In order to remove the memory module, spread latches on both sides of the slot and after the memory module pops up at a 30 degree angle pull it from the slot by the edges.
Dell Studio 1537 can take up to 8GB RAM total. You can install up to 4GB RAM module into each slot.
You should use DDR2 PC2-6400 SODIMM memory modules.
Loosen four (red) screws securing the heatsink.
Remove one (yellow) screw securing the cooling fan.
Disconnect the cooling fan cable from the motherboard.
Carefully lift up the cooling fan assembly and separate it from chips on the motherboard.
Remove the fan assembly.
If thermal grease on the processor looks dried out, you can clean it up with a paper towel soaked in alcohol and apply new thermal grease.
Remove three screws securing cooling fan to the heatsink.
Remove old thermal grease from the heatsink if needed.
Separate cooling fan from the heatsink assembly.
You can see it’s possible to replace just the cooling fan without replacing the whole fan assembly.
When the cooling fan removed you can take a closer look inside the heatsink.
In my case the heatsink was clogged with dust. My customer complained that his laptop shuts down while running games and now I know why.
The laptop was shutting down because of overheating. Cleaning the heatsink will fix this problem.
If your cooling fan makes noise, you can take it apart and apply a small drop of multi-purpose oil.
This might help to fix the fan noise. If not, you’ll have to replace the fan.
In the following steps I’ll show how to remove the keyboard.
If you just replacing the keyboard, it’s not necessary to go though all previous steps.
Remove two screws securing the keyboard.
Lift up the switch board cover.
Be careful, the switch board still connected to the motherboard.
Ideally, you have to remove the cover without disconnecting the cable.
Remove two screws securing the keyboard.
Carefully remove the keyboard bezel.
The keyboard bezel removed.
Lift up the keyboard and place it upside down on the palm rest.
Now you can access two keyboard cables connected to the motherboard.
In order to remove the keyboard you’ll have to unlock both connectors and release both cables.
We’ll start with the wide cable.
On the following picture the big connector shown in the locked position.
The white lock opens at a 90 degree angle.
On the following picture the connector is shown in the unlocked position (the keyboard cable already removed).
The small connector opens up exactly the same way.
On the following picture the small connector shown in the unlocked position. Now you can pull the cable.
After both connectors unlocked and cables released, you can remove the keyboard and replace it with a new on if needed.
Alternatively you can search for a new keyboard by the Dell part number.
In my case the keyboard part number is 0KR766.
