A couple of years ago I bought a brand new y50-70 laptop.
Since the first start I noticed problems with the battery, it lasted for only 20-30 min at best.
Right after buying the laptop I got into several projects and changed the shdd for an ssd and also doubled the RAM (of course, invaliding my warranty) due to the laptop being very slow.
I overlooked the battery issue until today when I decided to buy a new one so I could get more mobile with my laptop.
Before doing that I had a hunch and opened up the battery that came with the laptop only to find that the soldering between the battery leads and controller has failed. This must have been like this since the day I bought it. I will try to resolder the connection and let you know the outcome, but this is not normal. QC should have noticed this issue right away. The controller pads have no trace of soldering on them.

Welcome to the Community Forums.
Would you have an overview shot of the location where soldering has failed? This is to identify from the manual if it was normal as we I do not see reported cases of such event at the moment. Surely, if this has been reported earlier with the warranty active, then immediate repair could have been done.

I uploaded the photos I have here: https://drive.google.com/open?id=1006mg86PJfvTEewF0nBAHjoMvTqCjm9i
3 tabs on the visible side were detached.
I tried soldering them back on but with no success.

I would discourage further DIY battery repair.
It is not recommended to disassemble the battery itself. The danger for both user and machine do not measure the risk of repair and would be best to rather have a replacement itself.

Yeah... already dropped it off at a recycling centre. Anyway.. hope you guys got the message. Otherwise the laptop (after changing RAM and SHDD to SSD) is totally awesome.
