With the increased prevalence of fast solid-state hard drives, why do we still have system hibernation?
Good article! In my case, I normally do not use Hibernation since my desktop runs 24/7 (boot times are longer, despite a good SSD, due to the HBA card in it and I run some processes at night). However, I keep Hibernation enabled since my UPS uses it to prevent loss of work in progress should it have to shut down my computer because of a power outage (it's done so once since I got the UPS). I'm more likely to use Hibernation with my notebook when on the road.
i use it because it doesn't close your programs and it uses ZERO power
I thought it was replaced with the hybrid shutdown in Windows 8...
How prevalent are SSDs really? Last time I looked they still cost 10x as much as HDDs per gigabyte.
They are more "prevalent" than you apparently believe. If one has only one drive in a computer and it is used for the OS, programs, and data storage, then, yes, they are still overpriced. However, if one uses a separate boot drive for the OS and programs and keeps data on a separate drive, then SSDs suddenly become extremely practical. In that scenario, SSDs do more for the performance of a computer, especially when it comes to boot and program loading times, than anything else for the same money. Such a scenario is very popular with people who build their own computers and is gradually being adopted in higher end prebuilt computers.
AGREE. This feature is essential to me.
I use Hibernation all the time. It saves me booting up cold and waiting for Windows and other programs to get updated, etc. It saves power (most important these days). Having an SSD (if they were really economical to buy) would make no difference to my usage.
Just curious, its "safe" to use Hibernation instead of Shutdown in a way of not using shutdown daily. Just four commodity sake.
Yes, 3.14×10195% safe. And that's a pretty huge number. I shut my laptop down last today, after about a month.
On my Windows laptop, I do not use hibernate. I find a clean reboot really seems to help things along. Waiting for a boot once a day is a reasonable price to pay for stability.
On my Linux laptop, I have hibernation set up, but do not use it directly. I suspend the machine when not in use. Power consumption is very low, and restart time is instant, just open the lid and type in my password on the lock screen. However, if I forget it on while not plugged in, or don't use it for a while, like leaving it in suspend mode while on a camping trip, for instance, it will drop into hibernate automatically, saving my work.
Why not just put in sleep mode? Thats what I do. I do have it setup to use hybrid sleep. Not to sure of the difference though.
Generally do a full re-start about once a week just in case one of the programs has a memory leak.
Hybrid sleep also saves the current state of your computer to the HDD (or SSD), just like hibernation, so, if the power is interrupted during sleep, you will still be able to return to the state the computer was in just prior to going to sleep.
I also restart my desktop machine roughly once a week (it runs 24/7 otherwise). I don't schedule restarts; I just manage to need to roughly that often for things like program and system updates, software installation, user FUBARs, etc.
Fouled Up Beyond All Recognition. Except most folks use a different F word.
Thanks allot good info!
We use hibernation at work because of the reduced power consumption compared to sleep. Saying it uses zero power isn't necessarily true depending on your other settings. For instance, our machines are all set to wake on LAN which does mean the computer is able to receive those packets. If your BIOS is set to turn the computer on at a certain time it will also be using power to handle that process.
In addition to the reduced power, WOL won't work if the machine is in sleep mode, only powered off, which hibernate gets you. Since our boot times can be longer in labs due to group policy processing hibernation also gets the machine in a ready state faster than powering off does. We certainly can't afford to move all of our lab computers to SSD, yet, so the slower drives makes it worthwhile to use hibernate. Most of the computers get restarted on a regular basis when software updates are installed so that's not a concern for us.
