A:AnswerYou didn't get a bad one! The white indicating bar inside only moves to show the amount it is charged when unplugged. The plug symbol inside is what indicates that it is being charged.
A:AnswerYou just hit I believe it is f10 while starting up to enter the boot manager and can install windows from a USB stick or flash drive or whatever. When you install it, it should automatically find the OEM license of the motherboard and you shouldn't even have to activate windows when it installs.
A:AnswerIt has 1 NVMe slot, where the boot drive is. It can be upgraded, and it also has 1 2.5 inch drive bay for a SATA SSD/HDD. Only two slots, but there's still enough room to get good storage on the laptop.
A:AnswerI doubt it will be on sale because prices are inflated due to COVID-related supply shortages and high demand ($99 is the normal price). I suggest adding it on the Hotstocks app and then refreshing the page repeatedly throughout the day if you miss it. It seems like Best Buy tends to add them in waves after they come in stock. I lucked out and got one hours after I thought I'd missed out by randomly refreshing the page at 1 AM, but this was several weeks ago.
