I am planning to switch to a full SSD. Is this possible? Which SSD would it take? I mean measurements/ports wise.
The bottom case of my Lenovo Y40 has a crack. I have searched the internet for a replacement part but can not find one. Do you have any suggestions on where I can get one? Thanks.
Mine did the same thing. This is my 2nd Lenovo Y series, and both have casing issues. The 1st one is desk-bound due to damages to the cables in the hinges after the casing started falling apart. For the 2nd one, I bought an accidental warranty (thank god), and sure enough, they had to send it in to get the housing replaced due to cracking and a popped rivet for a screw hole. not to mention my touchpad stopped working in less than 1yr of ownership. The original Y40 they sent me had defective speakers out of the box. They hot-plugged it for me at least. I think I learned my lesson, not buying another Lenovo quality sucks. I just called again today because my touchpad and mouse stopped working… the lady I spoke to was trying to blame the Windows 10 upgrade, which has worked fine for about a month. Blah. Good luck with yours. I suspect you have 2 options use it as is and hope it doesn’t cause harm (like my 1st one), or send it in and $$
Daniel,
I have 2 of these. It’s the exact same model. One belongs to my son. They were purchased on the same day. We both had the same exact issues. Touchpad, keyboard, hinge… Mine also only had battery issues (the batteries suck! and have been replaced twice), and I only hS Bluetooth capability for about a month. They fixed it once but then refused to fix it again, claiming it was a software issue that was not covered by our 2-year extended warranty (thank goodness we got that because we both needed it multiple times!). I’ve never had more issues with a computer than with this laptop. I’m amazed it still works, to be honest. I almost always need to have it plugged in to use it. The battery dies within a few hours, being in sleep mode. I think this is an IdeaPad. Well, it seemed like a good idea at the time. :(“
Can I place a subwoofer inside a Lenovo Y40 like the Y50 model? Are there any connections for that?
Hey, how would one go about replacing the keyboard for this computer? thank you.
Quick question: will this work as an extra thing of RAM? looking to fix my battery, and upgrade just a bit 🙂 http://www.amazon.com/Crucial-PC3-12800-204-Pin-Notebook-CT102464BF160B/dp/B006YG8X9Y/ref=sr_1_4?ie=UTF8&qid=1440289037&sr=8-4&keywords=8gb+ddr3+ram
The main problem I’m having is putting the bottom back on
Oye amigo sera que le puedo cambiar el procesador quitar el intel core i7-4510u por una intel pentium G4560
I guess whoever made this instruction set did not really remove the keyboard. It appears that the only way to replace the keyboard is to melt the welds holding the keyboard cover plate in place. What a horrible design!
What did you do? I am having the same problem. I need to replace the keyboard as well.
When replacing the keyboard, it looks like one has to replace the white bezel that everything mounts to. Everything is riveted in!
You are correct. The only long-term, correct keyboard replacement method is to replace the palm rest/keyboard assembly. Unfortunately, other manufacturers made laptops with this same design. Yes, it is an incredibly horrible design. IMO, it’s a way for the manufacturers to make laptops more disposable since replacing the assembly (since it’s so hard to find one at a reasonable price) is usually not economically feasible.
