Re: Effect of suspend on computer life?

Laptops should produce very little, if any, heat while in suspend mode.

Although I'm inclined to concede that you have a point, I think it would be awesome to have this quantified in some way. Otherwise, I'm tempted to regard it as speculation, and therefore less noteworthy.

Re: Effect of suspend on computer life?

Now that I'm thinking about it, I believe the battery plays an important role. The worse made and the older the battery, creates more heat with little draw. While in suspend I don't think any fan can come on which doesn't help. I don't even think that hardware temperature safety limit works in suspend. I also believe the performance varies from manufacturer and different models and age.

Just saying from experience, (5 laptops, Linux, Win Vista, Win7) treat it like it's on if you block the airflow. If it's not off, then it's on. And that's with everything working correctly.

Re: Effect of suspend on computer life?

I suspend my laptop and toss it in my backpack--wrapped up in a slipcase--every single day, and it never heats up at all.  I didn't know this was a problem people had, since suspend-to-ram didn't even work under Linux on my last laptop (Toshiba Satellite), but then that thing did run hot in pretty much every situation.  I should probably mention that the Toshiba cost only $429 USD, while the Lenovo was much more expensive; perhaps price/quality is the major factor in this.  Then again, this isn't anything new in the world of electronics:  If your laptop/netbook is getting exceedingly hot when the cpu, gpu and hdd are all in active and not receiving power anyway, I'd be more apt to suspect a defective battery or poor design of that individual model than anything else (why hasn't anyone mentioned suspending while on AC?  Does that make a difference or not?).  Though now that I think about it: Yes, suspend-to-ram might indeed be an insidious plot concocted by Big Laptop to force us all to ditch our machines after only 5-10 years and buy new, vastly superior ones against our will.  The bastards!
