ThinkPad SL510 Speaker Repair & Reassembly Tips

Overview

After replacing the speaker assembly in a ThinkPad SL510 laptop, I share essential tips for putting everything back together correctly. The key lesson? Always power it up and test before putting all the screws back in. This video walks through the complete disassembly layout, screw organization, and proper reassembly sequence to avoid common mistakes that could lead to a second teardown.

Key Moments

• Organizing screws by location to ensure proper reassembly
• Careful handling of ribbon cables during disassembly
• Testing the laptop before final assembly
• Verifying all components (audio, keyboard, trackpad, LEDs) work correctly
• Successfully completing the repair with no leftover screws

Always fire it up before you put all the screws back because you do not want to take everything apart and test what you did.

Okay, so I’m back at it again with this IBM ThinkPad. I finally got the new set of speakers from eBay. If you recall, maybe you don’t recall, but in the previous video I took apart this laptop and noticed that the speaker’s wire was literally ripped off. So I went ahead and took everything apart.

The Challenge of Disassembly

This laptop required that I take apart everything underneath, including the CPU cooler, because there are a couple little screws down here that I need to take off in order to take off the bezel that goes over here. When the speakers are plugged in, when I lay them out, I have to run the wire down this path right here and they connect all the way up here, which is kind of insane. You put the speakers up there and then you have to run the wires up here, and that’s probably because the headphone jacks in this thing are right here. They probably run the sound card somewhere on the other side of the motherboard maybe, but yeah, it’s a lot of work.

Screw Organization

When I take apart the laptop, I start on the bottom. If I flip the laptop over, this is the layout of screws that way I put them back exactly where they belong because they’re different sizes. As you can see, these are the screen, and then these are the two little ones for the bezel. I try to group them so that I put them back as clearly as possible.

On this side we got the CPU cooler, and I previously put some thermal paste on it. I’ll have to move it around again so it’s nice and smooth.

Bezel Removal

The screen bezel, when you take these apart, you have to start by the inner part like this. Never start yanking the corners because you’ll rip it apart. You start by the middle and you start pulling out.

What else? I got the top bezel. Always disconnect these ribbon cables first before you pull anything apart because you will break them, and getting just those is impossible pretty much.

This is the bottom, the trackpad. Again, when you pull this apart, be very careful because these ribbon cables can rip off. Or this little guy right here, that’s just the light for the ThinkPad or these guys, these little lights too.

And we got the hard drive in this case, a 160 gig SSD, the optical drive which has a little screw that you must take off in order to slide out, and then the bottom cover over here.

Power Tip: Test First!

Here’s a power tip: Always, always power it up before you put all the screws back because you do not want to have to redo everything. So here it is powered up and the sound works again and everything else works. The mouse, the keyboard works, so just make sure that everything is working as expected.

These little guys, see that works? That’s because we’ve messed around with all those ribbon cables. We want to make sure that everything here lights up. Everything works. There’s no battery, so cool. Now we can finish up.

Final Assembly

And here it is. The audio is working, everything’s back together, all the screws are in. I didn’t have any extra screws, which is always a good sign, and all the little lights and everything works. As you can hear, also the bottom, everything is put together. And that’s it.

Final Tips

Well, thanks for watching. I hope this was useful. Remember, when taking these apart, be very careful. You don’t want to rip apart any of those ribbon cables. If you’re taking apart flexible plastic like this, you should always start by pulling from the inside, and if you do everything carefully and lay out your screws in the same way that the case is laid out, then you should be able to do this easily.

All right, so I hope you enjoyed watching. Subscribe if you like this kind of stuff. I do a lot of teardowns and repairs, and I’ll see you soon. Bye.
