After hearing enough times about how rebooting fixes a lot, what is the difference between cold booting and warm booting? I’ll explain the answer here.
The short answer is, cold boot means turn the computer off then on. Warm boot means to reboot the computer without shutting all the way down. The idea is that when you reboot, the computer stays warm since everything is still running. When you shut the computer off, it has a chance to cool down, hence (cold boot).
Warm boot is pretty straight forward, but to cold boot doesn’t mean turn the computer off then immediately back on. When you turn it off, leave it off for a good 30 seconds at least. This is how long it takes for the juices (power) to stop flowing through the main board and allow everything to have a chance to power off completely. Just because your screen shut off and there are no more sounds coming from the computer, doesn’t mean it is truly off all the way. Wait the 30 seconds or you may not fix the problem you are trying to repair in the first place.
How do you know when you need to warm boot versus cold boot? If you’re not sure, cold boot every time. Typically, a warm boot can fix any software issue, and cold boot can fix any hardware issues as well as software.
Although rebooting doesn’t fix everything, it fixes a lot. Now if you’re not sure what to reboot, that’s something else. If it’s your computer, that’s easy, if it’s Internet that doesn’t work for example, it could be your computer, your router, or your Internet modem. Cold boot everything if your not sure. You’d be surprised how much money you can save in computer repair technicians by just doing this one simple (shall I call it) trick!
Thanks for finally writing about > Cold boot versus Warm boot < Loved it!
When I initially left a comment I seem to have clicked on the -Notify me when new comments are added- checkbox and from now on
every time a comment is added I receive 4 emails with the same comment.
Is there an easy method you can remove me from that service?
Thank you!
Highly descriptive article, I liked that a lot. Will there
be a part 2?
Thanks for sharing your thoughts about computer repair how to.

It doesn’t actually uninstall it, but restores it to the state before you activated it so it doesn’t cause problems.
Once you’re under way, Google Maps can continue routing and even
handle simple rerouting of missed turns, but you’ll need
to be in range of a Wi-Fi hot spot at the beginning of every trip, somewhat limiting the usefulness of this
app. With the launch of series of highly appreciated Acer Tablets,
Acer has looked to conquer the Tablet world with elegant and practical designs, amazing features, and

[…] 1. Backups! Especially if you are in a networked environment, you will not get your data backed up if you leave files open. Don’t trust those shadow copy features that claim to backup even files that are open. I’ve seen them fail, and unless you are monitoring your backups, that’s one more thing to worry about. The best way to ensure backups are successful is to close everything that is open first. A couple of side notes to this: if you are in a domain environment with a server, every single computer needs to be turned off to ensure the server can backup properly. If you are one person, with a single computer and rely on online automatic backups, it’s a good idea to leave the computer on for some time with everything closed to ensure everything gets backed up. 2. No one can hack into your computer when it’s off, and you can’t get any viruses at that time either. 3. The computer has a chance to fully cool down. 4. The computer clears all memory making a nice fresh start when you turn it on and you may notice the computer is faster then, too. 5. The computer does a P.O.S.T. (Power On Self Test) when you turn it on. It may happen so fast you don’t notice it, or your computer is programmed to hide the display with a cool graphic instead (usually the manufacturers logo). The P.O.S.T. checks out the basic hardware and makes sure everything is in good working order. 6. Windows updates complete and check for new updates after each reboot or cold boot. […]
