Hello there,

I am the one who wrote this guide and still have this laptop, will be 4 years old this March and unfortunately, I have the exact same issue as you though in my case, it started on the left side but now, the right side is affected as well, albeit a bit less. In my case, it started with the base cover near the hinges where I noticed hairline cracks crossing the screw holes. What I did was take out everything including the motherboard and use epoxy adhesive (Araldite) and bonded the broken plastics that way. It is not perfect but it does the job and since the last 6-7 months, I have not seen any progression with the cracks.

My research suggests that this is a very common occurence with Lenovo laptops which are not metal. It is safe to say that the quality of plastics used by the company is not that good. Apart from this, the machine works perfect to this day.

Hello there, you can upload the photos on Google Drive, make them public and post a link here.

There is no CMOS battery for this model. The internal battery provides power for the RTC as well, verified as by disconnecting it, the BIOS settings get reset.

The screws should be about 2.5 cm.

Hi, I did not get to the keyboard but from what I believe is that the keyboard is riveted with plastic tabs or secured with screws (unlikely) with the palmrest. You need to take out the battery and the motherboard and then need to remove the insulation to expose the tabs. Then using a precision knife, you need to cut off those plastic tabs and the keyboard out. For securing the new keyboard, you can use some plastic and melt them with a soldering iron so that the keyboard stays flat. The best solution is to get the entire palmrest section as replacement with the keyboard attached.

You can try the local laptop repair shops or try eBay listings.

Hello Cristian,

TM (Tianma) and AUO (AU Optronics) are two OEMs who manufactured the LCD in the time. The AUO display is known to get faulty after sometime (vertical lines and flickering issue). So I would highly recommend the TM one. I have the TM and it has been more than 4 years. The display is still good as new.

It should be on the battery itself (one of the middle two pins). The battery has a controller board. I would be against removing the sensor due to safety. Replace the battery if necessary.

You need to restore the bootloader. There’s a tutorial on XDA on how to unbrick. xFSTK.

Replace the bridge cable connecting the motherboard to the daughter board.
