I haven't added to this thread for a while, so I thought I had better bring a problem to people's attention.
There is a bug in KLaptop, not because of PCLOS, but in the original code. I expect it will be fixed. It makes extra unnecessary checks to see whether your hardware can hibernate, and with later kernels, 2.6.22.x for example, it gives the info that the computer is not capable of hibernating when actually it is. All of a sudden, KLaptop doesn't include Hibernate on its menu after the kernel upgrade.
There are a number of programs which may control Suspend/Hibernate in your laptop and even some desktops. Look back through this thread. Look in Synaptic. The problem is that some may work on your laptop and some may not. If you have 20 different laptops laid out you may well have 20 different solutions. Sometimes you have to experiment.
If it's really desperate, you may have to either forget it or go for DSDT (see thread from beginning). Our kernel supports it, but again the solutions may vary a little.
If you need to post, start a new thread and put the name/number of your laptop in the title. With any luck, someone may have already solved the problem.
Where distros vary, it's often how they interact with different hardware. No-one here will be offended if another Linux works better with your lappy. An internet search may provide this kind of solution for you. As far as we are concerned, it's not Windows, it's all Linux and it's all Good.
Of course the developers will continue to do their best to make PCLOS work with as much hardware as possible, but we are a small team and only human...
