My laptop recently stopped working by not powering on properly (the screen was lit and I could hear the fans running but nothing would pop up on the screen) and my fiancé tried the F11 key and it brought us to a screen labeled “System Information” where we can run tests but the cursor on the touchpad was very fidgety and didn’t move, only glitched back and forth. I tried plugging in a USB mouse and still the same outcome. Touchscreen was also not working. The only way to control the options on screen was to use the arrows on the keyboard. When I ran a mouse/cursor test, the mouse performed fine, I was able to drag all the boxes and such. The touchscreen test didn’t go well though. Failed instantly, it’s almost completely unresponsive. Anyways, we decided to leave it alone for a couple days but now I’ve decided I’m just going to factory reset it and give up but when I go to turn it on, nothing happens. The screen doesn’t light up, I don’t hear the fans or anything. When I have the charger plugged in and I hold down the power button, the charger LED blinks three times then stops. I removed the back panel and removed the battery, waited 30 seconds, put it back in and tried again but still nothing happened. I don’t do anything extreme on my laptop either, no games or anything, just Facebook and Netflix mainly.
I don’t have very many nice things and this laptop was a gift to me as a birthday present and I really don’t want to part with it, it’s not even two years old. I’m not tech savvy and just getting into the back of the laptop and taking out the battery felt like a whole conquest. Please someone help me 😞 I have a video of the mouse glitching if anyone can also let me know how to attach a video here as well, I only see options for pictures. I have attached a picture of the System Information screen I had open but it’s low quality, it’s a screenshot from said video.

Quite a list.
Maybe you can match the blink code.
This will not work for everyone, but you may be lucky?
