Lenovo ideapad 300 battery failure

The battery for my Lenovo ideapad 300 – 15ISK has shown gradual degeneration and after less than a year it failed completely (battery report at the bottom). I’m deeply disappointed in Lenovo’s response to this. Initially they asked for having it in for repair, which in my case and I assume many others, is completely unacceptable. Being without a PC is extremely difficult and sending it away for a trivial issue like a battery replacement is unacceptable. But that was only the start of it, I checked Lenovo website and could not locate a replacement battery. Hence, I contacted Lenovo by phone but surprisingly I was told that the battery could not be sourced by Lenovo and I was recommended PC world or Amazon, neither have the correct battery in stock as it turned out.

A lot of battery suppliers are listed on Google but most of them has very limited description and it seems very easy to end up with the wrong battery. I contacted Lenovo through Twitter asking for some assistance, but after several tweets explaining the issue, Lenovo vent quiet(!). A couple of weeks later I tried again, but with the same abysmal result. So, at the end, I gave up and ordered what hopefully is the right battery. Sadly, after Twitting Lenovo that I gave them up, they came back with the requested information…

Lenovo is extremely good at promoting themselves, but be aware the equipment might not be up to scratch and their customer support is certainly not, not on their website, not on the phone, not through Twitter and not in spare parts they stock.

Re: Lenovo ideapad 300 battery failure

With any computer maker, the only way to perform a repair is to send it in (unless they have on-site repair or Best Buy repair). 

If you'd like to perform the repair yourself, the part numbers for the battery are 5B10H71979, 5B10H70338, or 5B10H70340, 5B10H71978, 5B10H70339, or 5B10H70341 (they'll all work, just different suppliers) 


Lenovo has it on sale on its parts site:


Alternatively, here's one from eBay (seller based in Florida):


As long as you find a battery with the p/n listed above, it'll work. Some battery modules will also work with the 14 & 17 inch option of the ideapad 300.


Hope that helps Smiley Happy
