Just came by to say that the battery replacement was straightforward, once they were in stock.
I missed the notes about 61WH battery issues until mine was swollen and worrisome. I saw none in stock here and bought a no-name 55WH replacement, which was easy to install and never worked.
Last week the 61WH were back in stock, so I ordered a replacement and installed it. I’d already upgraded BIOS, and it all worked first try. There are all sorts of cautions and be-careful notes on forum instructions, but if you’re familiar with fine-pitch connectors and not ham-fisted or blind, you’ll do fine, as I’m about half-way myself.
Yeah, maybe I should/could have called Support, but this is the only issue in two years of use. I’m just glad to have it working as a battery-enabled laptop again!
