Here is how you do it: (1) Back up your data, obvs. (2) Put the tablet into download mode. Ensure that it is off, then press and hold the power button, the home button, and the volume down button at the same time. Use the volume up button to accept the warning that appears. In the upper right corner it will say PRODUCT NAME. Take note of that for the next step. (3) Go to SamFw, enter the model number, and download the appropriate firmware image for your locale. Extract it somewhere. (4) Download and install Samsung USB Driver. (5) Download and extract Odin. (6) Run Odin and load firmware files from SamFw. The filenames in the firmware package start with the name of the slot they belong in in Odin. If your tablet doesn't have cellular capability then there will be no CP file. Your firmware package will come with a CSC file and a HOME_CSC file. The former will wipe user data clean and the latter will preserve it. It's highly recommended to use the CSC file however, especially when reverting to stock. Don't...

You can use this to view the various sensors on your computer. A reasonable operating temperature range of a laptop hard disk is 5-60 C, but temperatures between 35-45 C have lower failure rates over prolonged exposure. You can get exact figures if you look up the model number of your hard disk and find its spec sheet. More likely, though, is that it's just a slow hard disk. You could try defragmenting, running windows disk cleanup, or closing unwanted background programs with the task manager.

On most modern vehicles, the fuel filter, fuel pump, sensors, and other ancillary hardware are all located in the gas tank. They're designed to last the life of the vehicle and as such aren't easy to service. Gasoline is pretty clean these days so there's little reason to change the filter unless you have a specific reason.

Yeah, should work just fine, but be mindful of the card's power requirements and that it will physically fit in the case.

Try using a microfiber cloth or lens cleaning cloth and some isopropyl alcohol to clean the lens. Otherwise it's probably banjaxed. Component-level repair is generally not done on PC parts, especially optical drives, which are pretty complex mechanically. I've had a good amount die on me for various reasons; bearing fails, laser carriage or tray gets jammed/derailed, etc. Something just gets tired and gives up the ghost, you know how it is. Send it back if it's in warranty. If not, CD/DVD writer drives are not expensive, one can be had for $30 or so, and replacing one is generally trivial.

Don't use a Q-tip, they leave fibers. Paper products are more abrasive than you might think. Use a microfiber cloth or lens cleaning cloth and a small amount of isopropyl alcohol.

Canon printers have a function where they can self-clean their rollers. It might need further service, but it's worth a shot. See https://support.usa.canon.com/kb/index?p...
