Startup Failure on Lenovo Laptop

[TheEthanMaverick]

So, my grandfather's laptop is a Lenovo Ideapad Flex 5 1470. He says when he tries to start it up, the keyboard lights flicker, then the whole thing turns off. He's never had any problems with it in the past. It's frustrating because I can't get my hands on the laptop due to quarantine, and I can only communicate with him through texting.

 

He does leave it on the charger all the time, so it very well could be a battery health issue. There's no cables other than the charger plugged in that could be interfering with the startup process.

I'd start by telling him to unplug it from the charger and remove the battery (if possible) to discharge all the capacitors in the board. Idk why but my Thinkpad E440 wasn't posting one day and doing this fixed it.
