If this happens, disconnect the external device if one is connected. After that, turn the power of the computer ON/OFF to restore the function. If this function can not be still used even if only one external device is connected, stop using the external device because its current is over the acceptable value of this computer. Some external devices may not be able to use the USB Sleep and Charge function. In this case, please try one or more of the following methods. ■Change the Power supply mode settings in the TOSHIBA USB Sleep and Charge Utility. ■Turn OFF the computer while external devices are connected.

User’s Manual10-1 Legal Footnotes Chapter 10 Legal Footnotes This chapter slates the Legal Footnote(s) information applicable to TOSHIBA computers. CPU*1 Central Processing Unit (CPU) Performance Legal Footnote. CPU performance in your computer product may vary from specifications under the following conditions: ■use of certain external peripheral products ■use if battery power instead of AC power ■use of certain multimedia, computer generated graphics or video applications ■use of standard telephone lines or low speed network connections ■use of complex modeling software, such as high end computer aided design applications ■use of several applications or functionalities simultaneously ■use of computer in areas with low air pressure (high altitude >1,000 meters or >3,280 feet above sea level) ■use of computer at temperatures outside the range of 5°C to 35°C (41°F to 95°F) or >25°C (77°F) at high altitude (all temperature references are approximate and may vary depending on the specific computer model - please refer to your PC documentation or visit the Toshiba website at http://www.pcsupport.toshiba.com for details). CPU performance may also vary from specifications due to design configuration. Under some conditions, your computer product may automatically shut- down. This is a normal protective feature designed to reduce the risk of lost data or damage to the product when used outside recommended conditions. To avoid risk of lost data, always make back-up copies of data by periodically storing it on an external storage medium. For optimum performance, use your computer product only under recommended conditions. Read additional restrictions in your product documentation. Contact Toshiba technical service and support, refer to TOSHIBA support section in chapter 9, Troubleshooting for more information.
User’s Manual10-2 Legal Footnotes A 32-bit version of the operating system is preinstalled on your computer unless explicitly stated that the operating system is 64-bit. See http://www.pcsupport.toshiba.com for more information. Memory (Main System)*2 Part of the main system memory may be used by the graphics system for graphics performance and therefore reduce the amount of main system memory available for other computing activities. The amount of main system memory allocated to support graphics may vary depending on the graphics system, applications utilized, system memory size and other factors. Battery Life*3 Battery life may vary considerably depending on product model, configuration, applications, power management settings and features utilized, as well as the natural performance variations produced by the design of individual components. Published battery life numbers are achieved on select models and configurations tested by Toshiba at the time of publication. Recharge time varies depending on usage. Battery may not charge while computer is consuming full power. After a period of time, the battery will lose its ability to perform at maximum capacity and will need to be replaced. This is normal for all batteries. To purchase a new battery pack, see the accessories information that shipped with your computer. HDD drive capacity*4 One Gigabyte (GB) means 10 9 = 1,000,000,000 bytes using powers of 10. The computer operating system, however, reports storage capacity using powers of 2 for the definition of 1 GB = 2 30 = 1,073,741,824 bytes, and therefore shows less storage capacity. Available storage capacity will also be less if the product includes one or more pre-installed operating systems, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary. LCD Over a period of time, and depending on the usage of the computer, the brightness of the LCD screen will deteriorate. This is an intrinsic characteristic of LCD technology. Graphics Processor Unit (GPU) Graphics processor unit (GPU) performance may vary depending on product model, design configuration, applications, power management settings and features utilized. GPU performance is only optimized when operating in AC power mode and may decrease considerably when operating in battery power mode.
User’s Manual10-3 Legal Footnotes Wireless LAN*7 The transmission speed over the wireless LAN and the distance over which wireless LAN can reach may vary depending on surrounding electromagnetic environment, obstacles, access point design and configuration, and client design and software/hardware configurations. The actual transmission speed will be lower than the theoretical maximum speed. Non-applicable Icons Certain notebook chassis are designed to accommodate all possible configurations for an entire product series. Therefore, please be aware that your selected model may not have all the features and specifications corresponding to all of the icons or switches shown on the notebook chassis, unless you have selected all those features.

User’s ManualB-1 Display Controller Appendix B Display Controller Display controller The display controller interprets software commands into hardware com- mands that turn particular pixels on or off. A high-resolution external monitor connected to the computer can display up to 1400 horizontal and 1050 vertical pixels at up to 16M colors. The display controller also controls the video mode, which uses industry standard rules to govern the screen resolution and the maximum number of colors that can be displayed on screen. Software written for a given video mode will run on any computer that sup- ports the mode. Some of display modes might not be supported depending on the external monitor which you use. If you are running some application (for example a 3D application or video playback and so on), you may use some disturbance, flickering or frame dropping on your screen. If that occurs,adjust the resolution of display, lowering it until the screen is displayed properly.
