The crack causes the touchscreen to behave randomly which has led me to deactivate it. I'm looking to replace this touchscreen with any capable touchscreen.

Is this possible?

Do you have a link to a guide?

Do you know where I can find this part?

Do you know where I can send it in for repair?

Lately I have been getting this problem when booting the computer: "2100: Detection error on HDD0 (Main HDD). Press Esc to continue". I used to press Esc and then the computer would boot normally, but the other day when I booted the laptop I just got a black screen and nothing reacting (even if the power button had light, but it would not even switch off). As I did not know what to do, I took the laptop to a technician.

He was trying another hard drive in the laptop to see whether it was a problem with my HDD or with the connector of the motherboard and concluded that the problem was the motherboard and it had to be changed. Basically, the connector is a bit loose, so the HDD moves a bit, what causes the connection problem. As it is quite a lot of money, I decided to take the laptop home and try to figure out a solution.

The solution that I have found is to place two cotton pads from the ones used to remove make up below the HDD, then installing the HDD and place another cotton pad in between the HDD and the sponge that is inside the case. With the added pressure of the pads, the HDD does not move and everything works fine so far. However, I feel that this solution is not the best one. So, I was wondering whether you have better ideas.

Is there any other solution that you can think of so the HDD does not move or to fix the connector without changing the motherboard?

Can you suggest other materials that may be better than a cotton pad?

Cheers!

before i ask my question to help with, i’d like to introduce the keyboard problem / issue of this notebook:

People buying this notebook are first amazed of the price-performance ratio…but then…oh no, some keys of the keyboard won’t work (like E, G, H, Fn, NUM8, NUM/…). There are several solution suggestions on the world wide web, which MIGHT solve the keyboard problem, but none of these solution solved my defect keyboard - so these “solutions” are no real solution, they don’t fix the problem, they’re just like crutches helping the ill, but not really healing the broken leg e.g. (i hope you understand this example :D).

Here is a list of the suggested solutions found on the internet:

1.) (my favorite one xDxDxD)

Origin of the problem (ootp):

Maybe mechanical strain on the keyboard or mainboard?! The WWW doesn’t know ¯\_(ツ)_/¯

Solution:

Remove the middle outside screws of at the back of the notebook, if this doesn’t help, try to remove all three middle screws - then your keyboard will work again - MAGIC (sry, this didn’t help mine, but still helped other notebooks, why, i explain downwards).

______________________

2.) (still not helping, but more explained than the first one)

OOTP:

A faulty keyboard cable isolation (maybe production error)

Solution:

Open the back of your notebook. Then Remove the battery. Take some thin plastic sheet and put it e.g. between the keyboard cable and the motherboard (or the found place of the damaged isolation). Assamble the notebook again. Done. (Also this solution did help some people - but again this solution didn’t help me)

______________________

3.)

OOTP:

??? Same as 1.) ¯\_(ツ)_/¯

Solution:

The opposite of solution 1.) : tighten the two outside (or all) middle screws at the back of the notebook. (also didn’t help me)

______________________

4.)

OOPT:

maybe a keyboard driver problem?

Solution:

After start up press a few key-combinations and then the keyboard will work again…hm.

Try:

• SPACE + G + E
• SPACE + H + E
• SPACE + NUM+ + E
• SPACE + G + H
• … what ever, nothings helps…

______________________

5.)

OOPT:

same points 1.) and 3.)

Solution:

Press hard at the keyboard, or at the upper case - the area between the down right corner and the mousepad (other words, the “blank” down right area of the notebook). Then the keyboard will work again (helped for a few weeks, but then i doesn’t help anymore - so it made the problem WORSE!!! —_—)

______________________

6.)

OOPT:

we don’t know

Solution:

Send the laptop to the Lenovo to let them repair it.

—> do not do this!!! as the WWW tells, it takes a lot of time, and Lenovos Repair Center seems not to be able to fix that problem.

______________________

7.)

OOPT:

defect keyboard.

Solution:

replace the keyboard with a new one.

—> do not do this!!! as the WWW tells, new keyboards won’t solve the problem - so it might be a keyboard production error or a mainboard what ever error.

(AND: you can’t really change only the keyboard. you have to change the whole upper case, which actually costs around 80$)

______________________

Did i forget any WWW solution?

None of these solutions i found helped me. Here comes my suggestion (NOT SOLUTION YET) of a possible origin of the keyboard issue:

When starting up the laptop, i figured out that the keyboard starts working after a while - sometimes after 15 min, 30 min or an hour. After startup i tried to put mechanic preassure onto my upper case or keyboard, because i supposed a loose connection inside the keyboard madrix or mainboard (compared to the WWW solutions above). I seemed to help, but a few days later, i didn’t help anymore.

Then i figured out, that even without pressing on my notebook, the keyboard started working well after a while. If i left my laptop for 15 - 30 minutes, the keyboard won’t work again…then after working with the laptop again for a few minutes, the keyboard starts working well again….soooo, what is this? What could happen to my laptop, when leaving it?

COOLING DOWN!

When not working with your laptop (and windows is not doing any update what ever background cpu stressing stuff) your cpu will work less or maybe go into power saving mode. This will make your laptop cooling down in temperature.

This might explain, why the keyboard (when starting it up at room temperature at the morning) starts working after 15-30 minutes - but when leaving it, the laptop will not cool down to room temperature, so the keyboard will start working again FASTER (only 2-5 minutes).

So it MIGHT be a temperature problem?! We don’t know yet.

I tried out the following:

After startup, to increase the cases and laptops temperature faster, i moved my hand fast over the cover to produce frictional heat. This seemed to help a bit, but after a week my case and keys would look very bad xD.

Next step: HEAT GUN

After startup i tried to NOT doing any hard mechanical pressure on my case nor keyboard. Then i SOFTLEY (please do not melt or damage your laptop with a heat gun) warmed up my case and keyboard. After a few minutes (and not 15 - 30 min) my keyboard started working - an evidence of a heat problem?!

Step three: stressing CPU & GPU to produce heat

after i tried out the heat gun, i kind of prooved a heat problem. So i searched for an easy way to warm up the laptop not from outside, but from the inside out - and what are the most heating modules? RIGHT: the CPU and GPU.

I downloaded the two famous programms “Prime95” (stressing the CPU) and “FurMark” (stressing the GPU) and for monitoring of the temperatures “MSI Afterburner”. After starting up the system cold the next moring, again i tried NOT to stress the laptop machanically to exclude mechanical origins of the problem. Then i started the two programms and stressed the CPU and GPU for a while. I kept trying to press the non-functioning keys softly - after a few minutes, the keyboard starts working …. TADAAA another evidence of a head problem? :-)

And now severeal suggestions of the heat causing the keyboard to work again:

The heat could …

1.) (more a mechanical origin)

make the different materials (as metal, plasic and so on) of the mainboard, keyboard cable, outer case to strech in a diffent mass. This could lead to a loose connection to be connected again, so the keyboard start working correctley again .

2.) (more a electrical origin)

make the inner structure of maybe the keyboard controller (which is made of silicon and other metals) to work again - there are many chips on many devices at this planet having heat problems (e.g. devices/chips start or stop working when heating or cooling them). The reason for this also could be e.g. a bad designed PCB layout or not suitable circuit components.

3.) any other suggestions?

Suggestions #1 seems to fit the “screw suggestions” from above. But who knows.

And here comes YOU, the WWW!!! :-)

At the moment, i do not have any equipment, time and possiblilty to search for the heat-sensitive component. :-(

So my question to the WWW: is there anybody who can explore the heat-sensitive componente(s) and maybe also find out a solution for this (e.g. resolder the component with a heat gun)?

A last thing to any Lenovo Employee reading this article:

BLAME TO LENOVO!!! A such great company which stood for good quality, well producted, tank-not destroyable laptops, now started do produce such crappy stuff?

Many people like this gaming laptop very much….but a not working keyboard (on a GAMING laptop)?!?!?!

CMON we’re in the 21st century!!! 1000 satalites crusing around the world, AI coming up, but we cannot fix a keyboard problem???…what else to say :’-(

It feels like the right hinge may break apart, can this be fixed with ease. I use a iFixit Pro Tech Toolkit but overall never seen one taken apart.

Any help would be welcome!
