Y740 15" model battery replacement?

2019-06-13, 18:35 PM

In the user manual for the Y740, it states that it is compatible with the 76watt battery of the 17", but there is no option when buying the laptop? Where can I purchase this replacement? Thank you!

Hi mattdai01,

 

Welcome to the Community Forums.

 

Would you have the link to the manual?

I believe that it would be better to review compatibility of those parts.

 

Checking with parts lookup for the  for both 15 and 17 inch Y740 and seems that the battery part numbers do not show compatible against each. 

 

Lenovo encompass would be one of the authorized parts distributor and would also show if your model is compatible.

 

Update us soon as convenient.

 

Regards

Hi mattdai01,

 

Greetings.

 

Most likely the manual implies on general specifications which would depend on each model variants. As example, CTO machines or custom to order variants can have 76Whr battery depending on the order needs of its custom made parts but may not apply to each Y740-15ICH.

 

To see if the compatible parts, you can share your machine number /MTM (ex. 81HE000WRK) from the sticker or get it here.

 

Once we identify the battery part number specific to your machine, the same parts lookup page have configuration based on compatible tab to check.

 

Update us soon as convenient.

 

Regards

Are you able to check in any schematics files or anything for the y740 what the maximum battery voltage is?

Update:

According to a representative from Lenovo, the 17" battery is, in fact, compatible with the 15" chassis.

I replaced the 17" battery into my Y740 "15 few 1 month after getting mine. Fits just fine. The mobo has all the screw points for the larger battery pack. You'd lose the 2.5 drive capacity but I don't need it since I can get teh Intel 660p MVE SSD for like $95. I've been totaling 5-6hrs with normal web browsing and office work with throttlestop profiles. Never play games on battery so I don't have drain time for that.

 

Part #L17M4PG2

Check out the inside layout from these 2 review  and you can see all the mounting points for the battery packs line-up. I can post picture if requested.

Based on this last post and some posts on Reddit and notebookreview about this, I'm confident enough to say it's compatible. Thanks everyone.

Hey guys,

 

I have the Legion Y740 - 15IRHg model, which is a little newer I think. A you can see in the picture, it still supports the 17" battery. This battery is a little different though than the one you guys were discussing.On Lenovo's website, I found the correct battery for the 17", but I'm not sure where to find/buy it. Where did you guys get yours? Could I just call Lenovo for it?Thanks
