  • Ignition and EXTINCTION of 8 GB clip and reset does not work

    Hello

    I have a sansa clip 8 GB. It's 2 months warranty. When I turn it on it immediately turns off. I noticed that it intermittently goes on and stop on the kitchen table.

    I tried the "reset", now on the button (slide) in position "ON" for 30 + dry but its still the same.

    I tried to connedt it to a pc, but it stops again, so I can't reformat or work with it somehow.

    The battery is charged 3/4. It has been completely loaded before this problem.

    Is he dead?

    Solved the problem.

    Basically, I went to drain the battery. I have it plugged into my PC and he recognized her immediately. Looked in the root folder and there was about 20 funny looking for files with unusual name (like letters) tags

    I let it charge for a while and reformatted using the settings on the clip. This removed all the music. I currently use it for radio and it works perfectly without any problems. I'll add music next week and see how it goes.

    I'm wondering if it charges via a USB instead of the PC may have caused the problem, or was it a corrupt music file?

    Happy to...

    Anyway hope this helps someone out there...

    My iDevice doesn't connect to iTunes, I think its a result of the apple mobile device service. The restart option doesn't come up, it just says  "start the service" and when I click that an error comes up which says "The Apple Mobile Device Service service on Local Computer started and then stopped. Some services stop automatically if not in use by other services or programs". (I've already got a post with this information on I just wanted to make it more clear)

    If your iOS device does not appear in iTunes, try the following:

    1. Open Control Panel > Device Manager
    2. Plug in your device
    3. Locate Bus USB Controllers > Apple Mobile Device USB Driver.
      It is also possible that the device may appear under imaging devices, portable devices or other devices or as a device USB of MTB.

    5. Click Browse my computer for driver software

  • Computer maintenance and its importance

    Computer maintenance is the practice of keeping computers in good state of repair. I have well maintained computer can live well beyond its "life expectancy."

    Computer maintenace can take two forms. The first is to physically clean the computer itself and the second is by cleaning the 'virtual computer '. The virtual machine is inside your computer, system files, documents, programs, etc. Here is a good list of tips and tools that you can use to keep your computer.

    Virus protection

    Install anti-virus software to protect you. There are many programs that are available to help protect yourself you against viruses are created every day. Ask 10 different people what antivirus program, you should get you'll get 10 different answers. You may need this option to find out which antivirus program you prefer and run with it research. As long as the program is updated regularly, you will find that you are taking the right step in the right direction.

    Update regularly, check your settings of your antivirus program. Many of these programs come by default to search for and install updates regularly (usually once a day). If your program is not defined that way I would strongly advise to search for and install updates on a daily basis. Every day without the latest definitions are everyday you find yourself vulnerable to the latest virus.

    Applications


    Each application and utility are prone to security risks. The developers of these applications can find a breach in security and patch it, if you don't have the latest version, you can find yourself open to attack.

    Remove unused programs. If you have not used a program in a long time, then it is likely that you don't need. Many unused programs can represent free space that is not available to you because you have a program that you have installed a year ago. Many new computers have testing programs and other software that you might find that it is not enough. By removing unused software, you can help up to free space that you can use later on the road.

    Clear temporary files and other unnecessary files


    When you use the Internet a copy of every web page you visit is stored. This is useful because it allows for faster viewing later on the road. Say I visit Facebook every day, in theory the first day, I'm going it can be slow to load, but every day it's going to be faster as the day of the original. While this works great it does she become a resource hog when you already visited 10000 Web sites last month. Since it is space occupied at least once a month you should consider to erase temporary internet files, internet history and cookies out of your system. Here's how to delete information on the three most used browsers.

    Internet Explorer

    Chrome

    Firefox

    The next thing you want to do is clean out that downloads the file. What happens so you go to a site and you decide to download any software. If you click on it and it downloads and then you run it. The program installs and everything works fine with the program, you are quite right? No! What of this file, you need to download? It is still on your computer and it is absorbed to free space. Only a single file resumes May 5 k of space, but let's say download you 20 apps, oh are you want to look at the pictures if you have downloaded those as well. Now take a little space that you can not use your downloads. Cleaning of your download folder can help find some of this space lost on your computer.

    The download folder is easy to access

    1. Click Start
    2. Go to 'My Documents '.
    3. Downloads

    You should consider to keep this cleaned once a month. If you find that you download a bunch of stuff then you might want to dump this on a more regular basis.

    While we're on the subject of clean up the record of downloads let's talk about these zip files. If you receive a bunch of files (or even a single file) and it is in a zipped file, the first thing you need to do is to unpack. When you unpack the compressed file does not disappear. Once you have checked that you need out of compressed form file was safe to remove that file zipped as it is needlessly occupy space.

    Maintain the integrity of the data


    At least once a month, you should check your hard disk for errors by using two simple solutions.

    The first thing you'll do is a defragmentation of the hard drive. When you use data on your computer on a regular basis data gets fragmented throughout your entire hard drive. While you can see an MP3 file, your computer see pieces of this file that can be spread in the entire hard drive. You tell to defragment the hard drive the program to go find all the pieces and put them back together.  In making them together again and find this single file, you notice that specific file is significantly faster and other aspects of your computer can speed up.

    The next tool to use is a Check Disk. The disk check will focus on volumes of records and see if it finds problems, if that is the case he will try to fix it for you. Very hard to solve problems can be simplified by running a checking the disk for bad sectors, or the repaired lost clusters.

    These two programs are built into Windows and are ready for you to use.

    1. Click on my computer
    2. Right click on your hard drive (usually drive C), and then select Properties
    3. Click the Tools tab and you should see these options.

    Backup


    How important is your data? The most important that your data are for you more you save. Generally, once a month backup solution works for most people. However, all critical files should be backed up as regularly as you change them. There are many programs that enable to backup your data on a CD, jump drives or storage online. You should examine the different options and find the best fit.

    Windows updates


    Windows pushes updates on a regular basis. Check your settings in windows to check you are download and install these updates because they are coming. Critical updates for windows can save you any questions, you can finish by the experience.

Jump off the plate and drop the ball clean with little of isopropyl alcohol and remove any dried grease, oil or dust.
