For many of us, our lives can be quite hectic and busy at times, so the temptation to get as much done as we can while on the go has a lot of appeal. But is it really a good idea to have our laptops powered up and running while in a backpack or bag as we commute between locations, or is it an invitation for trouble?
Laptops generate heat and include fans to remove that heat from the electrical components. Stuck in a bag the fan cannot do it's job. Left in this condition long enough, your hardware is going to experience problems, if not fail altogether.
Good grief, Charlie Brown!
The likelihood of running over a large enough bump to jostle your laptop while it is doing a drive read/write is so high to me that it musy be said. The kump up may not be all that horrible but the relative G forces seem to me to be more than high enough to cause a head crash. Go ahead do a kernel build and ride down not over some rail road ties. I am sure this will cause you the aforementioned grief.
Seriously, I do not recommend anyone to ride a bicycle or other somewhat unstable device (unicycle, roller skate, blades, skateboard, etc) while computing on a laptop. I have dealt with many head crashes from laptops that were dropped while stationary so I do not see that having a recent drive would make any real difference as the basics of HDD haven't changed that much in the past 30 years.
Neglecting the heat issue a laptop equipped with an SSD should be immune to the motion related concerns addressed in this article. Improved battery life and quieter/cooler operation are other benefits typically associated with SSDs in mobile devices.
That what I was about to say. A laptop with such a drive will be safer, so if someone wants to keep their device running while commuting, there'll be no problem. If it explodes because of overheat, well...
Simply change your settings so that the laptop goes to sleep (now the same as hibernating) when you close the lid......sorted!
I have had my laptop in my rucksack (just like in the picture) when it was supposed to be asleep but wasn't. After a 3 hour journey - walking, train, underground, bus - it was certainly hot, but not overly so when I finally removed it, and no damage was done (well, none that I am aware of - whether it significantly reduced the life of some of the components I will never know).
Why would you keep it RUNNING in the bag? That's what sleep/hibernate is for....
the last time I had a customer bring me a laptop that wouldn't sleep (it had locked up while she was using it, and she didn't know you could hold the power button to force a power-off), it was so hot when I pulled it out of the bag that I nearly burned my hand on it.
