Chapter 1. Safety information This chapter presents following safety information that you need to be familiar with before you service a Lenovo Notebook.
Electrical safety Observe the following rules when working on electrical equipment. Important: Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.
– Use caution; do not become a victim yourself. – Switch off power. – Send another person to get medical aid. Safety inspection guide The purpose of this inspection guide is to assist you in identifying potentially unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service technicians from injury. This guide addresses only those items.
2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective. When handling ESD-sensitive parts: • Keep the parts in protective packages until they are inserted into the product. • Avoid contact with other people. • Wear a grounded wrist strap against your skin to eliminate static on your body. • Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap.

Chapter 2. Important service information This chapter presents the following important service information that applies to all machine types supported by this manual: • “Strategy for replacing FRUs” on page 27 – “Strategy for replacing a hard disk drive” on page 28 – “Important notice for replacing a system board” on page 28 • “Important information about replacing RoHS compliant FRUs” on page 28 Important: BIOS and device driver fixes are customer-installable.
• If an adapter or a device consists of more than one FRU, any of the FRUs may be the cause of the error. Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change. Replace only the FRU that changed the symptoms. Strategy for replacing a hard disk drive Always try to run a low-level format before replacing a hard disk drive (HDD). This will cause all customer data on the hard disk to be lost.
Chapter 3. General checkout This chapter presents following information: • “What to do first” on page 29 • “Power system checkout” on page 30 Before you go to the checkout guide, be sure to read the following important notes. Important notes: • Only certified trained personnel should service the computer. • Before replacing any FRU, read the entire page on removing and replacing FRUs. • When you replace FRUs, it is recommended to use new nylon-coated screws.
• Diskette drive damage caused by pressure on the diskette drive cover, foreign material in the drive, or the insertion of a diskette with multiple labels • Damaged or bent diskette eject button • Fuses blown by attachment of a nonsupported device • Forgotten computer password (making the computer unusable) • Sticky keys caused by spilling a liquid onto the keyboard • Use of an incorrect ac power adapter on laptop products The following symptoms might indicate damage caused by nonwarranted activities: • Mis
• If the problem persists, go to Chapter 5 “Lenovo E49 and ZhaoYang E49” on page 37. Note: Noise from the ac power adapter does not always indicate a defect. Checking operational charging To check whether the battery charges properly during operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. Perform operational charging.

Chapter 4. Related service information This chapter presents the following information: • “Recovering the computer settings” on page 33 • “Passwords” on page 33 • “Power management” on page 34 Recovering the computer settings Performing backup and recovery operations using the OneKey Recovery Pro program The OneKey Recovery Pro program enables you to back up all your hard disk drive contents including the operating system, data files, software programs, and personal settings.
Power management Note: Power management modes are not supported for APM operating system. To reduce power consumption, the computer has three power management modes: screen blank, sleep, and hibernation. Screen blank mode If the time set on the “Turn off monitor” timer in the operating system expires, the LCD backlight turns off. You also can turn off the LCD backlight by pressing Fn+F2. To end screen blank mode and resume normal operation, press any key.
• If a “hibernation time” has been set on the timer, and if the user does not do any operation with the keyboard, the hard disk drive, the parallel connector, or the diskette drive within that time. • If the timer conditions are satisfied in suspend mode. When the power is turned on, the computer returns from hibernation mode and resumes operation. The hibernation file in the boot record on the hard disk drive is read, and system status is restored from the hard disk drive. Chapter 4.
