DANGER: Always use the genuine batteries or replacement batteries authorized by Toshiba. Batteries other than those differ in specifications and are incompatible with the computer. They may burst or explode. To avoid leakage of alkaline solutions, never heat or disassemble the battery packs.
Page 131
For AC input, be sure to use the AC adapter and AC power cable that come with your computer or Toshiba-recommended equivalents. To avoid the risk of electrical shock, make sure that all the replacement components meet the specifications of the computer and that all the cables and connectors are fastened securely.
See the appropriate explanations and figures for screw sizes. To avoid personal injury, use care to handle components that have sharp edges or corners. After you have replaced a FRU, check that the FRU works correctly to ensure normal computer operation. TOSHIBA NB100 Maintenance Manual...
Check that all the required screws are used to secure the FRUs. Using wrong screws can damage the threads or heads of the screws or does not ensure that the FRUs are secure. After installing a FRU, make sure that the FRU and computer work normally. TOSHIBA NB100 Maintenance Manual...
