  • Page 6: General Safety

    G50-30/G50-45/G50-70/G50-70m/Z50-70 Hardware Maintenance Manual General safety Follow these rules below to ensure general safety: • Observe a good housekeeping in the area where the machines are put during and after the maintenance. • When lifting any heavy object: 1. Make sure that you can stand safely without slipping. 2. Distribute the weight of the object equally between your feet. 3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift it. 4. Lift it by standing or pushing up with your leg muscles; this action could avoid the strain from the muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or that you think is too heavy for you. • Do not perform any action that causes hazards to the customer, or that makes the machine unsafe.

  • Page 7: Electrical Safety

    Safety information Electrical safety Observe the following rules when working on electrical equipments. Important: Use only approved tools and test equipments. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Many customers have rubber floor mats near their machines that contain small conductive fibers to decrease electrostatic discharges.
  • Page 8 G50-30/G50-45/G50-70/G50-70m/Z50-70 Hardware Maintenance Manual • Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds. • Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage. • Do not service the following parts with the power on when they are removed from their normal operating places in a machine: – Power supply units – Pumps – Blowers and fans – Motor generators and similar units. (This practice ensures correct grounding of the units.) • If an electrical accident occurs: – Caution: do not become a victim yourself.

  • Page 9: Safety Inspection Guide

    The power cord should be the type specified in the parts list. c. Insulation must not be frayed or worn. 4. Check for cracked or bulging batteries. 5. Remove the cover. 6. Check for any obvious non-Lenovo alterations. Use good judgment as to the safety of any non-Lenovo alterations. 7. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage. 8. Check for worn, frayed, or pinched cables.

    G50-30/G50-45/G50-70/G50-70m/Z50-70 Hardware Maintenance Manual Handling devices that are sensitive to electrostatic discharge Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge. Notes: 1. Use product-specific ESD procedures when they exceed the requirements noted here.

    Strategy for replacing FRUs Before replacing parts: Make sure that all software fixes, drivers, and BIOS downloads are installed before replacing any FRUs listed in this manual. After a system board is replaced, ensure that the latest BIOS is loaded to the system board before completing the service action. To download software fixes, drivers, and BIOS, follow the steps below: 1. Go to http://support.lenovo.com. 2. Enter the serial number or select a product or use Lenovo smart downloading. 3. Select the BIOS/Driver/Applications and download. 4. Follow the directions on the screen and install the necessary software.

  • Page 21: Strategy For Replacing A Hard Disk Drive

    Important service information Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs: • If you are instructed to replace an FRU, but the replacement does not solve the problem, reinstall the original FRU before you continue. • Some computers have both a processor board and a system board. If you are instructed to replace either of them, and replacing one of them does not solve the problem, reinstall that board, and then replace the other one. • 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. Attention: The setup configuration on the computer you are servicing may have been customized. Running Automatic Configuration may alter the settings. Note the current configuration settings (using the View Configuration option); then, when service has been completed, verify that those settings remain in effect.

    • If the computer does not charge during operation, go to “Checking operational charging”. To check the AC adapter, follow the steps below: 1. Unplug the AC adapter cable from the computer. 2. Measure the output voltage at the plug of the AC adapter cable. See the following figure: Note: Output voltage for the AC adapter pin No. 2 may differ from the one you are servicing. 3. If the voltage is not correct, replace the AC adapter. 4. If the voltage is acceptable, do the following: • Replace the system board. • If the problem persists, go to “Lenovo G50-30/G50-45/G50-70/G50-70m/ Z50-70” on page 26. Note: Noise from the AC 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.

  • Page 26: Checking The Battery Pack

    G50-30/G50-45/G50-70/G50-70m/Z50-70 Hardware Maintenance Manual Perform operational charging. If the battery status indicator or icon does not light on, remove the battery pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator or icon is still off, replace the battery pack. If the charge indicator still does not light on, replace the system board. Then reinstall the battery pack. If it is still not charged, go to the next section. Checking the battery pack Battery charging does not start until the Power Meter shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or from having a shortened life. To check your battery, move your cursor to the Power Meter icon in the icon tray of the Windows® taskbar and wait for a moment (but do not click it), and the percentage of battery power remaining is displayed. To get detailed information about the battery, double-click the Power Meter icon. Note: If the battery pack becomes hot, it may not be able to be charged.
