Important service information 17 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. Strategy for replacing a hard disk drive Always try to run a low-level format before replacing a hard disk drive. This will cause all customer data on the hard disk to be lost. Make sure that the customer has a current backup of the data before performing this action. Attention: The drive startup sequence in the computer you are servicing may have been changed. Be extremely careful during write operations such as cop ying, s avi ng, or form att ing. If you s elect an i ncorrect drive, data or p rograms can be overwritten. Important notice for replacing a system board Some components mounted on a system board are very sensitive. Improper handling can cause damage to those components, and may cause a system malfunction. Attention: When handling a system board: Do not drop the system board or apply any excessive force to it. Avoid rough handling of any kind. Avoid bending the system board and hard pushing to prevent cracking at each BGA (Ball Grid Array) chipset.
Lenovo G400/G500/G405/G505/G410/G510 Hardware Maintenance Manual 18 RoHS, The Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive (2002/95/EC) is a European Union legal requirement affecting the global electronics industry. RoHS requirements must be implemented on Lenovo products placed on the market after June 2006. Products on the market before June 2006 are not required to have RoHS compliant parts. If the original FRU parts are non-compliant, replacement parts can also be non-compliant. In all cases if the original FRU parts are RoHS compliant, the replacement part must also be RoHS compliant. Note: RoHS and non-RoHS FRU part numbers with the same fit and function are identified with unique FRU part numbers. Lenovo plans to transit to RoHS compliance well before the implementation date and expects its suppliers to be ready to support Lenovo’s requirements and schedule in the EU. Products sold in 2005 and 2006 will contain some RoHS compliant FRUs. The following statement pertains to these products and any product Lenovo produces containing RoHS compliant FRUs. RoHS comp lian t FRU s h ave u niqu e FRU p art nu mbers. Before or a ft er t he RoHS implementation date, failed RoHS compliant parts must always be replaced with RoHS compliant ones, so only the FRUs identified as compliant in the system HMM or direct substitutions for those FRUs may be used. Note: A direct substitution is a part with a different FRU part number that is automatically shipped by the distribution center at the time of the order.

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. Remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall and recharge it. To check the battery pack, follow the steps below: 1. Turn off the computer. 2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 7 (-). See the following figure: 3. If the voltage is less than +11.0 V DC, the battery pack has been discharged. Note: Recharging will be continued for at least 3 hours, even though the indicator does not light on. If the voltage is still less than +11.0 V DC after recharging, replace the battery. 4. If the voltage is more than +11.0 V DC, measure the resistance between battery terminals 5 and 7. The resistance must be 4 to 30 KΩ. If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board. 1(+)2(+)3456(-)7(-) Terminal 1 +0 to +14 7 Ground (-)Voltage (V DC)
