Stealth won't run on battery

JPKCoffs
My 2017 Razer Blade Stealth 13" has stopped running on battery. When plugged in to the adaptor eveything's fine, and battery level is reported as 100%, but take it off the adaptor, and down it goes. Won't start if not plugged in, and reboots when plugged back in. We've just had it in for repair a month ago, and would really love to not have to go without it again so soon. It got a new battery last time it was in for service, and has been working fine since we got it back until now. Is there anything I should try that might sort this issue without sending it in again?

Sounds like a serious problem. Did it also have the same battery issues before? Mind sharing your case number via PM and discuss everything from there?

Haven't opened a case for this problem yet - was waiting to see if I could sort it out without opening an RMA. It never had any battery issues before, although when it went in for warranty repair (screen issues) a month ago a swelling battery was detected, and a new battery was put in. In the month since then, it's been fine, then suddenly a few days ago it wouldn't run off battery. My son also uses it as a school laptop, so he's currently just taking his adapter to school. If we need to send it in for repair again, we'll time it for his school holidays at the end of June.

Case now opened and PM with case number sent.

I don't want to be too negative, but some of Razer's customer service people are amongst the most frustrating people I've ever dealt with. Three days ago, I was asked to run a battery report and send in the HTML output. I did that, and sent the HTML version to Razer. Razer Customer Support said they couldn't read it (I managed to open the attachment fine on both the device I sent it from and others) and could they have screenshots. So I opened the battery report directly from the email I'd sent to Razer, and screenshotted the 6 screens worth of report and sent it in. A few hours later, I get an email saying "thanks for the screenshots, but we really need the HTML version, could you send one". Now having sent the requested information multiple times in multiple formats including three times as an HTML file, I've been waiting nearly 3 days for a reply, and have just received an email saying that Razer (who haven't answered my emails from 3 days ago) want to close the case because it's gone three days without activity, and telling ME off for not replying, when my emails have gone unanswered. It's like Fawlty Towers, only worse. Honestly, Razer needs to lift its Support game. It's unbelievably poor.

Hey @JPKCoffs! Sorry for the trouble. This is definitely not the experience we want for our customers. Let me assist you by taking over this thread since @Razer.Lauriat is not available. Please send me a PM together with your case ID so I can check its progress and determine if the attachments were really not readable.

Yes, it's not the experience that we want as customers either. It seems it may be a very simple issue like a loose battery connector, but of course as the machine is under warranty, I can't open it up and have a look. A week seems plenty for the Support Team to make the decision on whether the machine needs to be sent in. It's hard to know what the hold up is when we get no communication at all for days at a time in response to sending in the requested information. Anyway, PM sent with the case number. Any update you can give us on what is, or isn't, going on with the case at Razer's end would be greatly appreciated.
