NOTE: If NO is selected for Test Loop on the Test Parameter menu, the Test Status screen displays while the test is executing. When the test is complete the Memory Test menu displays. If YES is selected for Test Loop on the Test Parameter menu, the Test Status screen displays while the test is executing. Press Ctrl + break to return to the Memory Test menu Subtest 01 All one/All zero test This subtest performs pseudorandom data read/write. The data consists of all ones/all zero patterns produced by pseudorandom sequence generator. The test checks address error.
FFFFFFFFFFFFFFFF0000000000000000 0000000000000000FFFFFFFFFFFFFFFF
Walking 1/Walking 0 test (Left) This subtest uses running one/running zero patterns. This test sequence allows also to check system bus in maximum noise conditions. The following test sequence is written.
7FFF7FFF7FFF7FFF8000800080008000 BFFFBFFFBFFFBFFF4000400040004000
After all the memory being tested is filled with the pattern, it is read in descanting direction and compared with reference data. As the memory is read, the data is replaced with inverse test pattern. After all the memory is read and replaced with inverted pattern, it is read in descanting direction and compare with new reference data. As the memory is read, the data is replaced with next pattern, which is like first one shifted to right. Subtest 03 Walking 1/Walking 0 test (Right) Tee test method is the same as Subtest2. However, the data to be used differs.

Overview

This chapter describes the procedure for removing and replacing the field replaceable units (FRUs) in the PC. It may not be necessary to remove all the FRUs in order to replace one. The chart below provides a guide as to which other FRUs must be removed before a particular FRU can be removed. The numbers in the chart indicate the relevant section numbers in this manual. In all cases when removing an FRU, the battery pack must also be removed. When repairing an FRU that is the potential cause of a computer fault, use the chart to determine the order in which FRUs need to be removed. The tilt stand, if it is installed, can be removed without any other FRUs removed.
Chart Notation The chart shows the case for the following example: Removing a MDC All FRUs down to the 4.2 Battery pack to 4.11 Cover assembly above a SD board/Microphone/MDC must be removed.
Chapter 4 Replacement Procedures Safety Precautions Please read the following safety instructions before disassembling the computer and always follow the instructions while working on the computer. DANGER: 1. In the case of the battery, always use authentic parts or equivalent parts approved by Toshiba. Other batteries may have different specifications that are incompatible with the computer and may result in fire or explosion. Due to the risk of alkali fluid leaks, never attempt to heat or disassemble the battery. Similarly, due to the risk of explosion, never expose the battery to flame. 2. Some parts including the power supply and FL inverter generate high voltages. If you need to turn on the power while disassembling the computer, do not touch any connectors or other components due to the risk of electric shock. Also, do not disassemble individual parts when performing routine maintenance.
