Not sure why but if you want to see temperature info about your Dell laptop you can open “hidden menu” using your laptop keyboard just like this:
– Press FN + Shift button
– While pressing those buttons press 1, 5, 3, 2, 4
– Release FN and Shift
– Press FN + R
After pressing numbers you should notice that your scroll lock light start to blink and it will not stop that before you reboot your computer.
I can’t get this to work with Dell Latitude E6510 (Even that scroll lock light start to blink) but it works with Dell Latitude D420 and D430 so if you have Dell Laptop try this and let me know if it worked and if you know other hidden menu things like this let me know that too (write a comment).
