My Lenovo laptop is no longer functioning

My Lenovo Laptop (G50-70) can no longer work. Either it refuses to turn on, or I get a glitched screen with lines of static. I spent years on this laptop, so it holds value for me. What can I do to fix such?

Even a hard reboot is not a viable solution.

Attached is an example of the screen glitch.

L540 Bitlocker Preventing Repair

One day when booting up I get a message saying that the pc needs to be repaird and the boot configuration file does not contain valid information for an operating system. Then i download a copy of windows 8 from microsoft’s website to initialize the repair, since IT did not send the disk along when they gave me my laptop. When I try to run the repair it hits me with bitlocker and requiring a key to continue. Our IT has no idea where this key is and are not aware of setting one up. I went through microsoft with no luck. Azaure account with work mail but there are no keys stored there so this is my last hope. Where am I supposed to find these keys? Never was I asked to strore them or copy them or print them or anything. I’d really love some help. Thanks!

Lenovo X230 Fan Problem

So my X230 started to show a "CPU Fan Error" error lately at boot, although it’s very inconsistent. I turn it off and turn it on again and it boots normally. I have used a monitoring software (SpeedFan) to see if my temperatures are okay and I saw that my temps usually range from 69-75. SpeedFan also doesn’t show the fan speed or detects the laptop fan. I tried opening up the laptop myself and saw that whenever I turn it on, the fan woud speed really fast at boot then stops, which led me to believe that I had to replace the fan. So I took my laptop to a local repair shop (to free me the hassle of replacing the fan myself) but as soon as I got there, the technician just told me that the fan is okay, it only spins when the CPU gets too hot and stops spinning if it isn’t (which I think is complete BS), but I would like to consult other people and see if this is really the case.

P.S I’m new here so pardon if I make any mistake of posting this.

We will be happy to hear your thoughts
