A 56Kmodem does not guarantee all connections at 56K; rather it offers the ability to connect at upto 56K.Why is my CPU speed slower on battery?The SpeedStep technology that is resident on these notebooks adjusts the CPU speeddepending on the power source. SpeedStep will slow the CPU speed down to reduce batteryconsumption allowing for longer battery life. Once an AC adaptor is connected to thenotebook, SpeedStep returns the CPU speed to normal.Why am I getting no sound?The volume on the notebook is controlled by holding down the Function key andpressing the up and down arrow keys. The volume level is shown on the screen.Why do I get intermittent CD Read Errors?When a CD ROM drive intermittently reads a CD, it's normally caused by a dirty or scratchedCD, or a problem with the CD drive.Try reading different CDs to see if all or just one CD has trouble being read. If it's only aparticular CD, that CD is most likely scratched or dirty. CD cleaning kits are available at mostplaces that sell CDs. If all CDs have trouble being read, there may be a problem with your CDdrive.Why is my system running slow?If you have noticed your system running slower than usual it may be due to a fragmented harddisk drive. (Note: Other factors such as RAM memory, cache memory, and free space on yourhard drive may also affect system performance.) Your hard drive does a lot of reading andwriting and, over an extended period of time, it can become fragmented – this simply meansthat the files on your hard drive are not in continuous order, so the hard drive takes longer toload files or programs.To put your files back in order you use a program call Disk Defragmenter. This program willoptimise your hard disk drive by placing the files on your drive back in continuous order, andwill increase your notebook's performance.1. Tap Start > All Programs > Accessories > System Tools > Disk Defragmenter.2. Select the drive to be 'de-fragged'.3. Tap Analyze. Windows will indicate if this drive should be defragmented.4. If you need to defrag, tap Defragment to start the process.5. The time required to completed the defragmentation of the hard disk drive will dependon its size.
