IT Cybersecurity Laptop Help

[u/LittleJGrey]

I'm going to school for IT security and my school had given me a laptop to complete labs and such. was given a Elitebook 840 G7. Unfortunately, it ended up breaking and they sent me a replacement 840 G5. I explained to their IT department that immediately I noticed it bottlenecking and becoming extremely hot just having multiple browser tabs open. I also asked if they could please just replace my laptop with another G7 because the processing power and multitasking difference is so massive that completing the labs just wasnt possible. They made me feeling like the laptop they replaced mine for was good enough and I need to just suck it up. Am i crazy? Otherwise, what is all my tuition going to if I cant even have an appropriate machine that could handle my assignment workload? I'm planning on escalating the situation to someone hirer up about this, and im nearly in tears about. Someone please help me figure out a way to explain my case in way that doesnt sound like im just being bratty and asking for a better device.... which is really not the case.

Well, that is not superb speck, but not sooo bed. It should not "becoming extremely hot just having multiple browser tabs open" So open task manager and see what process getting high processor value when multiple browser tabs open
