Why won't my mouse or keyboard work after resuming from hibernation in Ubuntu?

If you have a laptop, the most likely reason your mouse or keyboard will not work after resuming from hibernation is that the power supply to the laptop has gone out. If this is the case, you can try plugging in your charger and turning on your computer. If that does not work, you may need to replace your power supply. On desktop machines, there are a few things that can cause problems with waking from hibernation. The first thing to check is if your machine has an active video card. If it does not, then it may be because of a driver issue and you will need to contact support for assistance. Another common problem with waking from hibernation is that certain files or folders may have been deleted while in hibernation and those files or folders will need to be recreated before Windows can start up again. Finally, sometimes hardware devices like mice or keyboards just stop working after being put into hibernate mode - this usually happens when they are left plugged in during hibernation and do not get unplugged until after Windows starts up again. In these cases, it usually requires rebooting the computer in order to fix the problem.

Is it safe to use hibernation on an SSD drive in Ubuntu?

Waking from hibernation on a Ubuntu computer is safe as long as the drive remains healthy. However, if the drive fails or experiences other problems, hibernation may not work properly and the computer may not be able to wake up from it.

To safely wake a computer from hibernation, you must first ensure that it is connected to power and has an active internet connection. Next, open a terminal window and type: sudo shutdown -h now To verify that your computer was successfully woken up from hibernation, enter: dmesg | grep hibernate If all goes well, you should see something like this: [ 0.000000] ACPI: BIOS revision 2.6 -> 2.6ubuntu2 [ 0.000000] ACPI: HPET id 0x8086a201 base 0xfed00000 [ 0.000000] clocksource: refined-jiffies: mask: 0xffffffff max_cycles:0xffffffff, max_idle_ns:19112604462750000 ns [ 0.000000] setup_percpu : NR_CPUS=128 nr_cpumask_bits=64 nr_cpu_ids=8 [ 0.000000] percpu : initialized [ 1.535814] Linux agpgart interface v0 .103 (c) Dave Jones [ 1.536952] Serial : 8250/16550 driver , 4 ports , IRQ sharing enabled [ 1.537253] 00 : ttyS0 at I/O 0xb000300 (irq = 3 ) is a 16550A console [ 1.537259 ] 01 : ttyS1 at I/O 0xb000400 (irq = 4 ) is a 16550A console , serial8250 compatible [ 1.537427 ] 02 : ttyS2 at I/O 0xb000500 (irq = 5 ) is a 16550A console , serial8250 compatible ; bootconsole disabled because of kernel oopses ...

How much power does my computer use when it is in hibernation mode in Ubuntu?

When your computer is in hibernation mode, it uses a fraction of the power it would use if it were running normally. This is because hibernation saves your computer's state so that you can resume using it later. When you wake up your computer from hibernation, it starts up from its saved state.

In Ubuntu, when you are in hibernation mode and press the power button to turn off your computer, the system will first try to enter standby mode (the low-power state). If standby fails due to lack of available power or if there is an error, then the system will go into hibernation mode instead. In either case, your computer will not use any more power than it would have while in standby or hibernation modes respectively.

Your computer's battery life may be shorter while in hibernation mode because the operating system needs more time to save its state. Additionally, some hardware components may need to be turned off during hibernation so they do not consume extra power when the machine wakes up.

You can check how much power your machine is using by opening a terminal and typing: sudo apt-get show-configuration | grep "hibernate" The output should look something like this: ... Power Management Settings: Hibernate Mode: enabled Standby Mode: enabled Suspend To Memory (S2M): disabled...

My laptop battery drains very quickly when I use hibernation, what can I do about it in Ubuntu?

Second, try using the "Wake on LAN" feature to wake your computer from hibernation or sleep mode remotely.

Hibernating automatically even though hibernate option is turned off?

If you have a laptop or desktop computer that is connected to the internet, and you want to hibernate it so that it will not use any power when it is not being used, there are several ways to do this. The easiest way is to turn off the hibernation option on your computer. You can also hibernate your computer by using Ubuntu's "Wake from Hibernate" feature. This feature will automatically wake your computer up from hibernation whenever you need it.

The first thing you need to do is make sure that your computer is properly configured for hibernation. Your computer must have a battery backup so that if the power goes out, your computer can still be restarted without losing any data. It should also have an AC adapter so that it can be turned on and off with the switch in the wall. If your computer does not have a battery backup or an AC adapter, then you cannot use Ubuntu's "Wake from Hibernate" feature.

To use Ubuntu's "Wake from Hibernate" feature, first open the System Settings menu by clicking on the gear icon in the top right corner of your screen and selecting System Settings from the menu that appears. Under Hardware tab, click on Power Management and select Wake From Hibernate under Allow Wake On Demand Options . Select Enabled under When Do I Want To Be Woken Up From Hibernation . Click Apply Now .

Now every time you want to wake up your computer from hibernation, all you need to do is press F5 key on your keyboard. This will start up Ubuntu's "Wake from Hibernate" feature and after a few minutes, your machine will automatically come out of hibernation and start working as usual.
