yoga2 pro: (official parts replacement videos?) (webcam not detected anymore) (overheating problems)

2019-05-18, 1:16 AM

hi all ,this is my first post :-) 

I have a yoga2 pro (20266  model) in which I have basically two problems: one seems connected with overheating which causes system instability and a series of different BSOD errors in win 8.1 and the other is about the webcam which is not detected anymore (in win 8,1 but also in lubuntu 18.04)
About the overheating: also in "balanced mode" fans are almost always on, and it was not the case before.

I am currently handling it by switching to  power saver mode with passive system cooling policies (ie, basically reduce cpu performance before using fans)  which usually brings cpu cores temperature down by 15-20 Celsius degrees (ie from 65-70 to about 50 degrees), GPU is usually around 45-50. No issues of that sort when using Lubuntu 18.04, system stays silent: I also tried to open the laptop and clean the air vents/fans with compressed air but without disassemblying them: for what I could see some dust/lint were there, but apparently not in large amounts. I am aware that I should probably disassemble the parts in order to clean them more thoroughly and perhaps applying new thermal paste, but I am intimidated by the connectors/parts which are unfamiliar to me. I also have considered malware and scanned for it but my impression is that the cooling system is simply unable to handle full performance mode for more than 1-2 minutes, sometimes even less.
So, the questions: are there official lenovo videos for parts replacement/removal for yoga2 pro (or as much as similar models?)


I saw this page https://support.lenovo.com/us/id/solutions/ht505031 but yoga2 pro seems not to be listed. I am also looking specifically for infos on webcam repair/removal/replacement (for example, which connector on the system board/video cable/etc may be involved?) I saw from some other forum posts that cables running hinges might have to do with this webcam problem, but it referred to other models  https://forums.lenovo.com/t5/Lenovo-Edge-Yoga-LaVie-Z-Flex/Yoga-11s-Camera-not-working-anymore/td-p/1345687/page/2 

Thanks in advance :-)

Hi pacio!

Welcome to the Community Forums!

You can use this link https://download.lenovo.com/consumer/mobiles_pub/lenovo_yoga_2_pro_hmm.pdf to go to the Hardware maintenance manual of the Yoga 2 Pro. This will teach you how to properly disassemble the machine.

As for the video disassembly guide listed on https://support.lenovo.com/us/id/solutions/ht505031, you can refer to the Yoga 2 11 / Yoga 2 13 as a reference as they're identical to the Yoga 2 Pro.

Let us know if you have any questions.
