Lenovo Yoga 500 (80N400PNUK) Power Button Replacement - Help!

2018-03-06, 21:10 PM

Hi Everyone :)

 

I have a Yoga 500 141BD (model number: 80N400PNUK) which has a broken power button. It became recessed after being pushed in too vigorously (not by myself I may add) and although I managed to pop it back out, it has obviously lost connection and was wondering how I would go about replacing the button. 

Would this require work on the motherboard itself or require a new part?

 

I would be greatful for any advice,

 

Thank you

 

Lesley.

Note: I am aware that this model of laptop can be switched on using a paper clip, however I would like to resolve the issue instead of using an alternative method.

Hi Lesley_P,

 

Greetings.

 

With MTM 80N400PNUK motherboard part number 5B20K17778 as image shown below have the power button integrated in the motherboard similar to this discussion. There is no specific part number for the button alone.

 

Hope this helps answer your query.

 

Regards

Thank you very much for your reply. Do you know if it would be relatively easy to fix?

Hi Lesley_P,

 

It would be better if a service tech can check it if a DIY solution can be made since it may all depend on how the it got loosened (can be a port or a button issue).

Thank you for your reply and I appreciate your time.

 

I repair and upgrade PCs and Laptops for a living, however as a rule I don't usually work on laptop motherboards unless it's a pretty straighforward fix so I'm just wondering if anyone has had a similar problem and what the outcome was. I would ideally like to try and fix the issue myself, however if it's going to be too complicated I will cut my losses and go to someone who specialises in Mobo repair.

 

Thanks,

 

Lesley

Hi Lesley_P,

 

Greetings.

 

The project may need some creative DIY if possible (minimize costing repair) as most technical repair done in the facility usually ends up with motherboard replacement.
