Q: This will provide the best area to calibrate your scale. Gently push on the surface a few times in different areas to make sure it doesn’t shake or wobble. If you’re unsure if the surface is level, use a carpenter’s level to check, or place a small ball or pencil on the surface to see if it rolls off. The mouse pads will act as a “dampener” to reduce vibrations that can interfere with the scale calibration. If you don’t have a mouse pad, you can use a gripping pad, or rubber pot holders. The location of the power button will vary based on the brand of the scale. Normally, it is located on the front face of the scale with the rest of the buttons, but it could also be a switch on the back or side of the scale. This will be located on the face of the scale, where the weight is displayed. Wait patiently while the scale clears any remaining data from previous uses. It may take a second, but your scale should show a “0.00” weight once it is zeroed. The instructions for placing your device in calibration mode will vary depending on the brand of your scale. Sometimes, there will be a button or switch, or you may have to press a series of buttons. Check the manual of the scale or search online to see how you should put your scale into calibration mode. Often, the manufacturer’s website will have calibration information for specific models.
A: Place the scale on a sturdy, level surface. Place one or two computer mouse pads on the table’s surface. Place your scale on the mousepad and power on the unit. Press the “Zero” or “Tare” button on your scale. Verify that your scale is set to “calibration” mode.

Article: Look under the bicycle seat to see if you have a lever that you can pull out, or if you have a bolt that will need to be loosened with a ratchet or wrench. The seat post telescopes into the bicycle frame and is fairly loosely fit into what is called the seat tube. The seat post is held in the seat tube by a binder bolt or quick-release lever. If you have a quick-release lever, you don’t need any tools to continue raising your seat. If you have a bolt, you may need a wrench, ratchet or Allen wrench. Most seat posts need either a 13mm or 14mm wrench, or a 5mm or 6mm Allen wrench. Loosen the bolt by twisting the bolt to the left, or counterclockwise, direction. While you’re sitting on your bike with your legs in the proper position, lift the seat up to where you can comfortably sit on it. Ask a friend to mark the seat position on the post with a marker so you will be able to place it at the right height once you’re off the bike. Move off the bike and move the seat to your marked position. The seat should slide up and down fairly easily, although you may need to wiggle the post a little bit to loosen it up. It should slide easily straight up and down. It is not suggested that you twist the seat from side to side, as this can cause scratches on the seat post. Pull the seat up to your optimum height.  Bicycle seats have a minimum insertion mark on their posts. This is the minimum amount that a seat post should be inserted into the bike frame, meaning that the seat cannot get any taller. If you need the seat higher or lower than it will actually go, your bicycle is the wrong size for you. To adjust the seat height of a recumbent bicycle, sit in the seat with your riding shoes on. Straighten one of your legs almost fully onto the pedal, but keep a slight bend in your knee. Move your seat forward or backward to ensure you have a slight bend in your knee while sitting. Usually, a recumbent bike will have a lever under the seat that you lift when you move the seat. A seat post that is hard to move might have too much friction or a tight fit inside the seat tube. If this is the case, remove the seat post entirely and use a lubricant to grease the inside of the seat tube. If you have a carbon-fiber seat post, use a dry graphite powder lubricant, which is available online, automotive store, or at a home improvement store.  Never apply grease to carbon fiber since it could degrade. If the seat post is totally stuck, look for the cause. It might be rusted, in which case you can use a lubricant or other oil for a steel frame to loosen it up, or ammonia if the frame is aluminum. If the seat post is the wrong size for the seat tube, you may need to pry the seat post out, possibly using a flathead screwdriver to assist you. Twisting the seat from side to side might also help loosen the seat. Once you get the seat post removed, either fully lubricate the post and the seat tube, or replace the seat post with a new one that fits better with your bicycle frame. The front pointed end of the seat should generally align with the frame of the bicycle. Look at the seat from above so you can see whether the seat lines up properly. Since all bodies are different, however, you might find it more comfortable to twist the seat a fraction to the left or right. Men often prefer a seat that tilts upward, while women are often more comfortable on a seat that tilts downward. This will be a minor tilt. Avoid the temptation to tilt the seat downward very much; even though it may be slightly more comfortable when sitting on the bike, it will actually cause more strain to your arms and shoulders. You may also have a tendency to slide forward when you ride if your seat is tilted too far down. This will cause you to push back with your arms and hands on the handlebars, further straining your arms as you ride. Try riding with the seat level at first, and add a slight tilt if it gets too uncomfortable over time. If your bike seat tightens with a bolt, use a wrench, Allen wrench, or ratchet to tighten the bolt. If your bike seat tightens with a quick-release lever, push the lever back in. You may need to tighten up the bolt side of the lever so that when you push the lever down, it will be tight enough. To do this, use a wrench to hold the bolt in place while you wind the lever. After every few turns with the lever, test it by closing it to see if it’s tight enough. If it’s too tight, then unscrew the bolt a few turns, and try the lever again.
Question: What is a summary of what this article is about?
Loosen the bolt or lever clamping the seat post. Mark your seat height on the seat post with a marker. Raise the seat. Lubricate the seat tube. Align the seat with the bike frame. Adjust the angle of the seat up or down. Tighten the bolt or the lever.

Q: If you cannot access the boot menu, follow the steps below. If you are able to choose what unit to boot from, start the installation process. Make sure your bootable drive (the CD/DVD or USB stick which Linux will boot from) is properly inserted.  You should manage to do it with the F10 button, but you can access this option via the main menu. The installation for version 10.10 is quite simple and the configuration is done on a visual interface.
A:
Start up your computer and enter the boot menu if possible and choose the media to boot the operative system from. Start up the machine and enter the BIOS by hitting the button the instruction manual for your motherboard/computer refers to, which is usually F1, F2, F10 or DEL, but it varies with the brand and model. Change the boot order and set CD/DVD or USB before your primary hard drive. Save and exit the BIOS. Turn off the computer when you are done with the backup your stuff and turn it back on again to boot Ubuntu and start "wubi", the installation program.
