My PC Heats Up While Hibernating

Asked By Kevin A Augustin 40 points N/A Posted on - 05/31/2015

My friend has been constantly putting his computer on a standby and hibernate mode. For a very very long time he has been doing this without any problems, but of late the computer has been very unstable and  its speed has also reduced. He has been handling it with a lot of care and he is linking the slow speed and the instability of the computer to the fact that he has been hibernating it most of the time. The most disturbing question is whether placing a computer system on a standby and hibernation modes can render a computer unstable and maybe crash it?

My PC Heats Up While Hibernating

Sleeping or hibernate mode the processor is completely OFF, it will not produce any hot air. It will not damage your computer. Hibernation uses no power. Ram stores its data to hard drive and it will retrieve when it reboots. Sleep mode computer use more power or electricity than a shutdown computer, power needed to run some circuit. RAM is a volatile memory. It has to maintain its data, so it needs electricity to hold data without any lose.

Computer can become unstable because of overheating. This may due to, 

1. Dust. Dust can be removed with compressed air.

2. Large number of application being installed, updated, uninstalled. Use ccleaner to remove unwanted files.

3. Hard disk problem.

4. Outdated OS and device driver software. Format the system and install the OS and device driver software.

My PC Heats Up While Hibernating

I don’t think hibernating or putting to sleep mode will make your computer very slow. It has nothing to do with the performance of the machine. The performance depends on the current stat of the system. On laptops, when you close the lid or you put the screen down while it is running, the machine will go to standby mode or sleep mode automatically.

In this state, the machine is still operating but at a very minimal state. In Microsoft Windows, there are two (2) sleep options available: Hibernate and Stand By. Stand By is the more traditional sleep mode. This type of sleep mode lowers down the power your computer uses to almost nothing.

When you’re in Stand By mode, the power to your peripheral devices, hard drive, and screen gets cut off but the power to your computer’s physical memory or the physical RAM remains allowing your files to stay open. In Hibernate, the computer saves an image of your desktop which includes all open files and windows and then it shuts down your computer.

In laptops, hibernate mode doesn’t happen automatically. You have to select it manually to activate it. On the other hand, standby mode is automatic. When you close the lid of your laptop, the machine will go to standby mode automatically. I don’t think you will have overheating problem during hibernation because the system is actually not running while in this state.

The processor is not running and the cooling fan is turned off that’s why there’s nothing to cause overheating. If you experience overheating while using the computer, you need to check the cooling system inside. Try cleaning the heat sink and the CPU cooling fan from dust. If the cooling fan is not working properly or has become slower, try replacing it with a new one.

For laptops, if you experience overheating and the device turns off, bring it to a computer shop to have the cooling system cleaned from the inside.
