While the PC is shut down but plugged in the power supply is actually still powering the BIOS chip instead of the battery, so unplugging the PC starts draining this battery. You shouldn''t worry much about this, the battery has a pretty long life (years) and it is replacable, and resetting the BIOS is simple. So just FYI.
While the plugs to most devices and appliances are perfectly safe to unplug while they are still on, you should always turn them off before. Here is a deep dive into why you should turn off things before unplugging them so that you can get yourself, and your home, safe.

In terms of physical appearance, they all are flat and circular.
We have an expert-written solution to this problem! An optical drive randomly becomes unavailable, and after replacing the drive, the technician now suspects a power issue. What
Battery Backups: What They Look Like . The front of the battery backup will usually have a power switch to turn the device on and off and will sometimes have one or more additional buttons that perform various functions. Higher-end battery backup units will also often feature LCD screens that show how charged the batteries are, how much power it''s using,
We have an expert-written solution to this problem! An optical drive randomly becomes unavailable, and after replacing the drive, the technician now suspects a power issue. What could help in this situation? Where would you configure a computer so that it powered down the display after it was not used for 20 minutes? a. Device Manager. b.
Unfortunately, current optical storage devices, including digital video discs (DVDs) and Blu-ray discs, can only record information in a diffraction-limited region within a layer beneath the
In preparation for the CompTIA A+ exam, this chapter covers many important details regarding the safe assembly and disassembly of your PC, voltage and power checks,
Follow these steps to replace the CMOS battery: Disconnect the power cord from the computer or the AC power source (electrical outlet or power adapter). Disconnect all
Technically best practice is to turn off the PSU, unplug then drain the capacitors by hitting the power button on the case a few times, then don your grounded ESD protection before opening it, but realistically just unplugging is plenty for 99.9% of situations.
Optical cables come in different qualities; some are fragile, while others have high-quality sheathing. Regardless of the type you have, unplug your optical cable carefully to preserve its lifespan. Below are steps to unplug your optical cable safely. Step 1: Locate the optical port and cable on your TV/Soundbar.
this article highlights di#erent approaches towards achieving this goal of higher density optical storage, either by increasing the density at the surface of an optical recording material, or by
For most computers, you only need to connect USB connector to the computer for the optical drive to work. However, in certain rare cases, the computer might not be able to

For most computers, you only need to connect USB connector to the computer for the optical drive to work. However, in certain rare cases, the computer might not be able to support enough power through a single USB port, and you will need to also connect USB connector for extra power.
Literally, without a laser beam, there are no optical storage devices. Optical Storage Devices are Mostly Flat and Round Plates (Discs) Compact Discs (CDs), Digital
When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to ±13 minutes/year. The CMOS battery is connected to an onboard header on the processor side of the board by a 1x2 connector (Molex 51021-0200). Example of battery location: Notes: The location of the battery varies depending

Specifically, while the optical disc is rotating, the laser source shines a light beam on its reflective aluminum layer. Hence, the device interprets the light beam by the optical disk drive’s photocell, which is built into the lens. This section highlights some of the features of optical storage devices.
In addition, the power supply might not fit without the removal of other devices, such as the processor, and such, but in most cases (pun intended) you should install the power supply without too much trouble. Next, connect the P1 connector to the motherboard and attach the Molex, mini, SATA, and PCIe as necessary to their corresponding devices.
The power supply is in charge of converting the alternating current (AC) drawn from the wall outlet into direct current (DC) to be used internally by the computer. It feeds the motherboard, hard drives, optical drives, and any other devices inside of the computer. Talk about a single point of failure!
One way you can avoid this problem is by storing the disk inside a protective case when not in use. Due to their small size and weight, optical storage devices can be easily misplaced or even stolen. Compared to other forms of storage devices, optical storage devices are significantly slower.
The only reason to unplug it when you've turned it off is to help protect it from lighting strikes. And that's a very rare thing. Turning it off when not in use is probably a good idea in an area where power outages are common, though it's probably not really helping. It certainly won't hurt.
If you need a lot of strength to plug in the connector, check and make sure that it is oriented correctly. Don't force the connection. Afterward, remove any antistatic protection, and finally, plug the power supply into the AC outlet, turn on the hard on/off switch (if the power supply has one), and turn on the computer.
