Ways to fix your Laptop

Slow Hard Drive

11-Ways-to-Fix-Your-Laptop_sh3Symptom:Excessive program load times, slow file transfers
 
Solution: 
Disk defragmentation

Disorganized information on your hard drive can sap performance because the computer requires more time to sift through data fragments and bad sectors on the drive. This problem can be cleared up easily (but not especially quickly; defragging can sometimes take hours) using the built-in Windows tool called Disk Defragmenter. You can access this program through the Programs menu in the Accessories or System Tools folder. Simply click the Analyze button to see if your disk drive requires defragmenting, and then click Defragment to begin.
 
Other options include the free Power Defragmenter, and Diskeeper 2007 ($29.95 Home edition, $49.95 Pro, $99.95 Pro Premier), which offers more features like complete automation, real-time defragmenting, and InvisiTasking technology, which allows Diskeeper to run in the background without draining resources.


Ways to fix your laptop

Overheating

11-Ways-to-Fix-Your-Laptop_sh2Symptom: 
Computer crashes, freezes
 
Solution: 
Clean out air vents, put filtered material over the inhalation vent, or update BIOS

Overheating can rob your laptop of performance and often cause a host of hiccups, such as system crashes and freezing. Every computer generates lots of heat, but laptops are especially susceptible to overheating due to their small size and lack of ventilation. Excessive dust can clog air vents and deprive your system of cold air to cool off the CPU. You can often solve overheating issues simply by cleaning out these air vents with a cloth or keyboard cleaner.

To prevent further dust buildup, place a piece of filtered cloth, say from a Swiffer, over the inhalation vent. Don't place one over the exhaust vent, as that's where hot air is supposed to flow out of the system quickly. If the cloth doesn't work, you may want to update your system's BIOS, which controls the laptop's hardware. Most manufacturers offer an installation file that updates BIOS files automatically, which often address heat management. Just make sure that your notebook is connected to the power supply when updating the BIOS.
