My laptop is quite old so sometimes annoying errors happen here.
Normally if you briefly press the power button, a small menu with 4 options pops up. You can put suspend, restart or shut it down. Somehow my laptop wont suspend, even though I closed the lid, so I have to do it by pressing the power button. Now recently when doing this, and whenever I have lots of tabs and documents open, my laptop would immediately shut down. This is unusual and frustrating, since I have to waste lots of time to reboot it.
Is it because the graphics card is simply worn out? Or what other explanations can you all find?
