1 Working inside your computer Safety instructions Use the following safety guidelines to protect your computer from potential damage and to ensure your personal safety. Unless otherwise noted, each procedure included in this document assumes that you have read the safety information that shipped with your computer. WARNING: Before working inside your computer, read the safety information that is shipped with your computer. For more safety best practices, see the Regulatory Compliance home page at www.dell.
5. Remove any media card and optical disc from your computer, if applicable. 6. After the computer is unplugged, press and hold the power button for 5 seconds to ground the system board. CAUTION: Place the computer on a flat, soft, and clean surface to avoid scratches on the display. 7. Place the computer face down. Safety precautions The safety precautions chapter details the primary steps to be taken before performing any disassembly instructions.
● Use a wired ESD wrist strap that is properly grounded. The use of wireless anti-static straps is no longer allowed; they do not provide adequate protection. Touching the chassis before handling parts does not ensure adequate ESD protection on parts with increased sensitivity to ESD damage. ● Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and workbench pads.
Transporting sensitive components When transporting ESD sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place these parts in anti-static bags for safe transport. After working inside your computer About this task NOTE: Leaving stray or loose screws inside your computer may severely damage your computer. Steps 1. Replace all screws and ensure that no stray screws remain inside your computer. 2.

5 Troubleshooting Handling swollen Lithium-ion batteries Like most laptops, Dell laptops use lithium-ion batteries. One type of lithium-ion battery is the lithium-ion polymer battery. Lithium-ion polymer batteries have increased in popularity in recent years and have become standard in the electronics industry due to customer preferences for a slim form factor (especially with newer ultra-thin laptops) and long battery life.
● Run thorough tests to introduce additional test options to provide extra information about the failed device(s) ● View status messages that inform you if tests are completed successfully ● View error messages that inform you of problems encountered during testing NOTE: Some tests for specific devices require user interaction. Always ensure that you are present at the computer terminal when the diagnostic tests are performed. For more information, see https://www.dell.com/support/kbdoc/000180971.
LCD Power rail test (L-BIST) L-BIST is an enhancement to the single LED error code diagnostics and is automatically initiated during POST. L-BIST will check the LCD power rail. If there is no power being supplied to the LCD (i.e., the L-BIST circuit fails), the battery status LED will flash either an error code [2,8] or an error code [2,7]. NOTE: If L-BIST fails, LCD-BIST cannot function as no power will be supplied to the LCD. How to invoke L-BIST Test: 1. Press the power button to start the system. 2.
The following table shows different power and battery-status light patterns and associated problems. Table 22. LED codes Diagnostic light codes Problem description Recommended Solution 1,1 TPM detection failure Replace the system board. 1,2 Unrecoverable SPI flash failure Replace the system board. 1,5 i-Fuse failure Replace the system board. 1,6 EC internal failure Disconnect all power source (AC, battery, coin cell) and drain flea power by pressing and holding down the power button.
Recovering the operating system When your computer is unable to boot to the operating system even after repeated attempts, it automatically starts Dell SupportAssist OS Recovery.
