Remove all screws from the bottom case.
There are several clips on the bottom shell. You can use a pry tool to release all the clips. Please be careful not to damage the clips.
After all the screws are removed, you can open the bottom case.
Under the bottom case, you can access the battery, hard drive, memory, wireless card, and speakers.
Remove the four screws securing the battery.
Disconnect the battery connector from the motherboard. You can remove the battery.
The laptop comes with a 7.4V, 7,400mAh Li-polymer battery, Lenovo P/N: L13M4P02.
Use your fingernail to gently separate the clips on both sides, and the memory module will pop out automatically.
The Lenovo Y50-70 has two memory slots, but it only comes with one memory module, so you can add another one.
The laptop comes with a Samsung 4GB PC3L-12800S 1600MHz memory module.
Remove the four screws securing the hard drive module. Slide it to the left.
The Lenovo Y50-70 featured an HGST hard drive.
Remove the screw securing the wireless card
Disconnect the two antenna cables and remove them from their slots.

Disconnect the speaker cable from the motherboard.

Remove all screws securing the heat sink.
Disconnect the two fan cables from the motherboard.
The cooling system of the Lenovo Y50-70 features two heat pipes and a single fan. It is worth noting that its fan is composed of two fans.
The Intel processor is soldered onto the motherboard, so it cannot be upgraded.

Hi, I can’t remove the bottom case. Can you please explain to me if I have to pull up the case or what to do? Of course, I removed all screws. Thanks!
You should pry up the bottom case with a pry bar or guitar pick, carefully release all the snaps, and please do not damage the snaps.
So what happens if you break the snaps? Is there any way to replace them? I broke all four of them up top towards the screen and a couple on the sides, and now whenever I press down on certain places on my laptop, it compresses and even makes a popping noise sometimes. Please help!
You may need to replace the back cover.
Hi,
I read online posts that the CPU is soldered on. Is it possible to upgrade the CPU for this laptop? I have a Lenovo Y50 with the Intel i5-4200H CPU, and I was hoping to upgrade to the i7-4700HQ CPU.
Thanks in advance.
Yes! The CPU is soldered on the motherboard; you can not upgrade it.
The rear four clips are impossible to reach, even with a plastic removal tool.
How do I unclip them?
I have a sound like a piece of paper is stuck in the fan, and I want to remove it if there is anything; the thing is brand new, and I do not want to take it to the local repair agents as they only employ retards. (Yes, they broke my previous one, and I had to wait 2 months for a replacement.)
Thanks
Erik
Bro, you just need to apply a lot of force and carefully break some of the clips, because that’s how they’re designed. I broke five of them with no problem. There are four left.
Hi, I unscrewed the laptop, and two of the screws broke in the process. Do you know what size these are, so I can order replacements? Thanks
I was trying to remove the back cover, but the plastic covering of the hinges was broken. The cover still works fine, but it leaves that open without protection. Does anyone know where I can buy a replacement cover for my Y50?
Be especially aware of the four rear clips right beneath the fan outlet on the back cover, as well as the ones by the network cable port. Installed a new SSD and broke all four of the rear clips, although they don’t seem to do a whole lot. Use a plastic pry bar (a spork works just fine) to unclip the ones at the network cable. I don’t know how to avoid breaking the four rear ones except to avoid lifting up the cover too much in the front. Good luck (you’re gonna need it!)
Is it possible to replace the keyboard? I found articles and videos showing a complete teardown of the keyboard. I’m a clutz and spilled liquid on my keyboard and shorted some keys.
Hi, can you mark or show which one is the BIOS chip on the motherboard? I kind of bricked mine and tried to fix it via the CH341A process. Thank you
Can I change the processor? I want to upgrade to a higher GHz processor.
The CPU and GPU are soldered to the motherboard, so they can’t be upgraded, unfortunately.
I’ve been trying to open the bottom case, but I can’t find any screws or snaps, and I haven’t been able to pry it open. I have a Lenovo G400. How do I get it open?
