Does Cone of Cold freeze water?

A 10th level Sorcerer standing on dry land casts Cone of Cold on a creature in water 10′ ahead of the spell caster.

Does the water freeze? The spell description doesn’t refer to any environmental effects.

A blast of cold air erupts from your hands. Each creature in a 60-foot cone must make a Constitution saving throw. A creature takes 8d8 cold damage on a failed save, or half as much damage on a successful one.

A creature killed by this spell becomes a frozen statue until it thaws.

The creature is not killed.

What could cause my MacBook Pro’s built-in trackpad to freeze?

When I reboot my laptop, the built-in trackpad works, so I’m fairly confident that it’s not a hardware problem, but when I’ve been using it for a while with my Bluetooth keyboard and trackpad, and then take it off its stand to use it without them, I found that the trackpad is frozen. It can’t be used even to move the mouse cursor, and it can’t physically click.

It’s a MacBook Pro (Retina, 13-inch, Early 2015).

I really don’t even know what the likely candidates are to investigate. What are possible causes of this problem?

Initial boot after installation works, all subsequent boots freeze on Dell Inspiron Mini

So I am having a weird issue, I actually noticed it with Linux Mint, but I decided to try Ubuntu to see if the problem originated there, and it does seem to. I have a little Dell Inspiron Mini 1012. Ubuntu 15.04 and older will install and works great. The trouble starts when I try to install 15.10 or 16.04. The installer boots fine, and I am able to install. I remove the USB drive I used and reboot. The system will fully reboot into the desktop, I am able to use the system if I choose. But when I shut it down and try to start up again, the system will freeze every time. I hit escape so I can view the list of what the system is doing, and it doesn’t seem to freeze on any particular thing each time, but it does freeze solid every time. No blinking cursor, no hard drive activity, nothing. After the first initial boot after installation, the system will never boot again. I am completely at a loss as for what to do, and would love to get the newer versions working on this system. If anyone needs more info, just let me know. Thank you.

How can a SSD freeze a notebook’s boot screen for half a minute?

My wife has a Toshiba Satellite C855D-11U and I got an idea that I’ll enhance its performance, so I bought a Kingston SUV500 120GB SSD. I put it into the notebook then after power on the TOSHIBA logo was shown for almost one minute. During this time I couldn’t do anything but when I pressed the F2 or F12 after one minute, the notebook opened the boot menu / BIOS.

When I put back the original Toshiba HDD, the bootlogo appeared for 1-2 seconds and everything went fine. I noticed that the problem also exist when I don’t use any SATA device.

The SATA mode in BIOS is AHCI, the USB Legacy is enabled.

What could be the problem?
