So I have an HP 14-af118au laptop that I've been using for about two - three (maybe? I forgot kek) years. Since I have been living in my own room (and college), I have been constantly falling asleep while leaving my laptop on, leaving it on overnight for 5-8 hours or so.

I have been doing this for quite a while and I'm worried I might be asking too much of it.

Here are the things I've done to my laptop: 1. I left my laptop on overnight in high peformance, no automatic sleep mode, while charging (Quite a few times) 2. I left my laptop on overnight in high peformance, but with sleep mode and charging 3. I left my laptop on overnight, but didn't charge it, so it lost its battery and shut down by itself (most common so far)

I have an external fan and my room has AC. But I have a timer to turn it off at 2 AM and I usually tend to my laptop at 6 AM or so. I'm worried because my laptop have been emiting faint metallic smell (perhaps burning?) and I would really like to keep it alive for more years to come.

Is it okay for me to treat my laptop like this? And is the smell something I need to pay attention to? It's faint, but I sometimes smell it.

    What is your question? – Appleoddity Dec 10 '18 at 3:48
  • Ah shoot. I forgot to clarify. I was wondering if it's ok to keep my laptop running like this, and if the smell is something to be wary of. – Xlennon Dec 10 '18 at 4:45
  • The fact that it is on high performance mode doesn't matter. That just allows your hardware to use more power when it is under a heavy load. When you're falling asleep, is the laptop on your bed, or on a hard surface? If it's on your bed, the reduced air flow and the laptop not being able to cool properly may be causing the metallic, hot burning smell. I would suggest changing the setting, so when the lid is closed, the laptop will enter sleep mode. – DrZoo Dec 10 '18 at 4:59

    A well made laptop should be able to run for years without ever being turned off. – Keltari Dec 10 '18 at 5:00

    I wonder what it is you're smelling. There's NO WAY a laptop can emit heat to vaporize anything metallic for you to smell. Burnt electronics do not smell like burnt metal. Are you sure it isn't some construction work outside? Welding and such? I can't imagine the laptop burning metal without being on fire. – Nelson Dec 11 '18 at 5:24

Is your laptop hot?

The "High Performance Mode" is only a setting. It doesn't mean it's actually running at maximum, but only it could run at maximum.

If your laptop is cool as if it is off, and no fans are running, then it wasn't actually doing anything, even though it was in "high performance mode".

Running it overnight isn't bad for the laptop at all. The worst is running it when the vents are covered. This is very easily done with beds. Do NOT stick a laptop on a bed/blanket/sofa and block the air vents. Even if it is just on and not doing anything, blocking all the vents will quickly heat it up.

Also, don't leave it on and stick it in a backpack... that's actually pretty bad too.

  • Nope. Always have open spaces on the sides of the laptop, and I use an external fan as well. I think peak temperature was like 80 C when my laptop starts making noises and normally it would be around 40 - 50 C. – Xlennon Dec 10 '18 at 15:17
