I have a 2016 RBS i7 and the battery has swelled up. I have contacted support and received a shipping label for RMA but it's out of warranty and I'm worried it'g going to be pricy just to replace the battery. I also don't want my computer to get wiped. I have found replacement batteries on ebay. If i order one can I run the RBS without a battery, just plugged in? Is that doable and safe for the computer?
