Another student purposely broke my laptop?

Am in high school, and my school has a bring your own device policy that allows students to bring their own laptops and tablets. This kid today picked up my bag and said "I hope theirs nothing valuable in here" and then dropped it on the ground. I just found out when I got home that the laptop is completely broken, the screen, keyboard, chassis, body, etc. Are all smashed in and shattered. This is a Lenovo Yoga 3 Pro which cost me $1300. I'm furious and do not know what to do. No phone number to my school is currently being answered (it is Friday). The policy for BYOD states that damage to property is not the fault of the school. I was not able to check the condition of the computer after it was purposely dropped because the final bell had rung just after the incident to go home. I'm realizing that I screwed up by not having time to inspect the laptop because it was last block just before the bell rang. I'm not sure if anybody else heard it, but he did purposely drop it after I said that my laptop was in it. Do I honestly have a legal stance here? I have emailed my superintendent, principal, assistant principal, and guidance counselor. I took photos of the damage, the laptop, the case, and the bag exactly as it was. I was with two friends that can vouch for me for two hours after school, I was not going into my bag. It was two hours after school that I left my friends and went inside and discovered it.

Added (1). I have another friend that I walked to my bus with, so I guess that he could vouch that I did not drop my bag going to the bus. I have a teacher that may have seen the laptop in perfect condition earlier in the day. What do you think?

My Lenovo IdeaPad Z510 is having charging problems?

My Lenovo IdeaPad Z510 is having charging problems. This started just around 3 days ago. My charger will be plugged in for a long time and my laptop will tell me that I have 99 percent or 100 percent but not even a minute after I unplug it from the charger, it will shut down and the battery life light will start to blink. I don't understand what is going on.

Can a Lenovo Erazer X315 run Fallout 4? (FX-8300, AMD R9 255)?

I want to get a new computer so I can run Fallout 4. I can *barely* run it on my current Laptop (i5-3210M and Intel HD Graphics 4000, 6 GB RAM).
(For reference, it runs Skyrim on Low/Medium, and GTA V on Low with just a little bit of lag).

The Erazer X315 has the following specs:
Processor: FX8300 3.3 GHz (8 core)
Graphics: AMD R9 255 (2 GB)
RAM: 8 GB

The Erazer is very cheap and is right in my budget level. Does anybody have any experience with this particular setup and Fallout 4?

Laptop fails after window logo during boot up?

I have a lenovo z570 ideapad and just like most people i got the windows 10 update. I was working on it really late at night and i fell asleep without shutting down the computer. This isn't the first time i've done that but normally i just wake it up from sleep mode and resume. This time i noticed my laptop was being extremely slow even though i only had just 2 programs open. So i decided to log off and restart it. Now my computer doesn't boot up normally. I see the lenovo logo followed by the windows logo but that's it it freezes or something. I don't see my log in screen.

i really hope you can tell me steps to let me do this on my own instead of taking it to a repair shop because i need it to finish my work! I tried the F8 thing too but it doesn't work. I hope you can at least point me in the right direction.
