I've noticed the back of the laptop heating up for the past year, and usually place the screen section on a USB-powered fan platform to reduce the heat. When I put it to "sleep" I then turn off the AC power. I've been able to run it without AC power for 2-4 hrs on numerous occasions. However, about a week ago when I tried to resume from "sleep" before turning on ACpower, the CPU suddenly turned off. At the time I was using an external USB modem which was plugged in. So I turned on the AC power, and restarted the laptop. That happened a few times, and at least twice I saw a brief message on screen saying the battery level was below 3%, so CPU was turning off. Usually in sleep mode battery storage would not drop below 93%. In the past week the battery has stopped charging. (Last night it said the battery level was 0%; all day today it shows 83%.) So I have to use the ACpower to keep the laptop running.
HP Battery check today produced the following results:

I'm instructed to replace the battery...
I've had this laptop since January 2015, and warranty expired in January 2016. I'm currently in SE Asia (far from any HP service centers). The battery in this laptop is "not replaceable" except by HP technicians, and I've not found any way to order a replacement battery. Any advice? Anything like an "external battery pack" available for this model HP ENVY x2 Detachable PC 13?
