When a laptop or portable device begins to malfunction, what should you do? The customer can replace some parts of a laptop, typically called Customer-Replaceable Units [CRU]. CRUs include such components as the laptop battery and additional RAM. Parts that the customer should not replace are called Field-Replaceable Units [FRU]. FRUs include such components as the laptop motherboard, LCD display, and keyboard. In many cases, the device may need to be returned to the place of purchase, a certified service center, or even the manufacturer.
Figure 13-3 shows an example of a CRU and FRU.

A repair center can provide service on laptops made by different manufacturers, or a repair center may specialize in a specific brand and be considered an authorized dealer for warranty work and repair. The following are common repairs performed at local repair centers:
■ Hardware and software diagnostics
■ Data transfer and recovery
■ Hard drive installation and upgrades
■ RAM installation and upgrades
■ Keyboard and fan replacement
■ Internal laptop cleaning
■ LCD screen repair
■ LCD inverter and backlight repair
Most repairs to LCD displays must be performed in a repair center. These repairs include replacing the LCD screen, the backlight that shines through the screen to illuminate the display, and the inverter that produces the high voltage required by the backlight. If the backlight has failed, the screen is visible only when you look at it from an angle.
If no local services are available, you might be required to send the laptop to a regional repair center or to the manufacturer. If the laptop damage is severe or requires specialized software and tools, the manufacturer can decide to replace the laptop instead of attempting a repair.
Caution
Before attempting to repair a laptop or portable device, check the warranty to see if repairs during the warranty period must be done at an authorized service center to avoid invalidating the warranty. If you repair a laptop yourself, you should always back up the data and disconnect the device from the power source.
Worksheet 13.2.0: Investigating Repair Centers
For this worksheet, you investigate the services provided by a computer repair center. Use the Internet or a local phone directory to locate one. After you have found a repair center, use its website to obtain information, and answer the questions in the worksheet. If a website is not available, contact the local repair center. Refer to the worksheet in IT Essentials: PC Hardware and Software Labs and Study Guide, Third Edition. You may complete this worksheet now or wait to do so until the end of the chapter.
