Introduction Important service information Important BIOS and device driver fixes are customer-installable. The BIOS and device drivers are posted on the customer support site http://www.
Strategy for replacing a hard disk drive Always try to run a low-level format before replacing a hard disk drive. Attention: The drive startup sequence in the computer you are servicing may have been changed. Be extremely careful during write operations such as copying, saving, or formatting.
Safety notice 1 Before the computer is powered on after FRU replacement, make sure all screws, springs, and other small parts are in place and are not left loose inside the computer . V erify this by shaking the computer and listening for rattling sounds.
Safety notice 2 DANGER Some standby batteries contain a small amount of nickel and cadmium. Do not disassemble a standby battery , recharge it, throw it into fire or water , or short-circuit it. Dispose of the battery as required by local ordinances or regulations.
(continuation of safety notice 2) Alcune batterie di riserva contengono una piccola quantità di nichel e cadmio. Non smontarle, ricaricarle, gettarle nel fuoco o nell’acqua né cortocircuitarle. Smaltirle secondo la normativa in vigore (DPR 915/82, successive disposizioni e disposizioni locali).
Safety notice 3 DANGER The battery pack contains small amounts of nickel. Do not disassemble it, throw it into fire or water , or short-circuit it. Dispose of the battery pack as required by local ordinances or regulations. Use only the battery in the appropriate parts listing when replacing the battery pack.
(continuation of safety notice 3) La batteria contiene piccole quantità di nichel. Non smontarla, gettarla nel fuoco o nell’acqua né cortocircuitarla. Smaltirla secondo la normativa in vigore (DPR 915/82, successive disposizioni e disposizioni locali).
Safety notice 4 DANGER The lithium battery can cause a fire, an explosion, or a severe burn. Do not recharge it, remove its polarized connector , disassemble it, heat it above 100°C (212°F), incinerate it, or expose its cell contents to water . Dispose of the battery as required by local ordinances or regulations.
(continuation of safety notice 4) La batteria di supporto e una batteria al litio e puo incendiarsi, esplodere o procurare gravi ustioni. Evitare di ricaricarla, smontarne il connettore polarizzato, smontarla, riscaldarla ad una temperatura superiore ai 100 gradi centigradi, incendiarla o gettarla in acqua.
Safety notice 5 If the LCD breaks and the fluid from inside the LCD gets into your eyes or on your hands, immediately wash the affected areas with water for at least 15 minutes. Seek medical care if any symptoms from the fluid are present after washing.
Safety notice 6 DANGER To avoid shock, do not remove the plastic cover that protects the lower part of the inverter card. Afin d’éviter tout risque de choc électrique, ne retirez pas le cache en plastique protégeant la partie inférieure de la carte d’alimentation.
Safety notice 7 DANGER Though the main batteries have low voltage, a shorted or grounded battery can produce enough current to burn personnel or combustible materials.
Safety notice 8 DANGER Before removing any FRU, power off the computer , unplug all power cords from electrical outlets, remove the battery pack, and then disconnect any interconnecting cables.
Safety information The following section presents safety information with which you need to be familiar before you service a ThinkPad computer . General safety Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance.
v After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective. v Reinstall all covers correctly before returning the machine to the customer . v Fan louvers on the machine help to prevent overheating of internal components.
– Ensure that another person, familiar with the power-off controls, is near you. Attention: Another person must be there to switch off the power , if necessary . – Use only one hand when working with powered-on electrical equipment; keep the other hand in your pocket or behind your back.
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 personnel from injury .
8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with. 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.
– Use the round ground-prong of the AC plug on AC-operated computers. Grounding requirements Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
If a CD-ROM drive, a DVD-ROM drive, or another laser device is installed, note the following: CAUTION: Opening the CD-ROM drive, the DVD-ROM drive, or any other optical storage device could result in exposure to hazardous laser radiation. There are no serviceable parts inside those drives.
A CD-ROM drive, a DVD-ROM drive, or any other storage device installed may contain an embedded Class 3A or Class 3B laser diode. Note the following: DANGER Emits visible and invisible laser radiation when open. Do not stare into the beam, do not view directly with optical instruments, and avoid direct exposure to the beam.

LCD-related symptoms Important The TFT LCD for the notebook computer contains many thin-film transistors (TFT s). A small number of dots that are missing, discolored, or always lighted is characteristic of TFT LCD technology , but excessive pixel problems can cause viewing concerns.
Intermittent problems Intermittent system hang problems can be due to a variety of causes that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a problem recurs.
FRU replacement notices This section contains notices related to removing and replacing parts. Read this section carefully before replacing any FRU. Screw notices Loose screws can cause a reliability problem.
v Make sure that you use the correct screw . If you have a torque screwdriver , tighten all screws firmly to the torque shown in the table. Never use a screw that you removed.
Retaining the UUID The Universally Unique Identifier (UUID) is a 128-bit number uniquely assigned to your computer at production and stored in the EEPROM of your system board. The algorithm that generates the number is designed to provide unique IDs until the year A.
3. To write ECA information, select 1. Write ECA/rework number from EEPROM , and follow the instruction. 4. To write box build date, select 4. Write box build date from EEPROM , and follow the instruction on the screen.
Removing and replacing a FRU This section presents directions and drawings for use in removing and replacing a FRU. Be sure to observe the following general rules: 1. Do not try to service any computer unless you have been trained and certified. An untrained person runs the risk of damaging parts.

Ein wichtiger Punkt beim Kauf des Geräts Lenovo G41 (oder sogar vor seinem Kauf) ist das durchlesen seiner Bedienungsanleitung. Dies sollten wir wegen ein paar einfacher Gründe machen:
Wenn Sie Lenovo G41 noch nicht gekauft haben, ist jetzt ein guter Moment, um sich mit den grundliegenden Daten des Produkts bekannt zu machen.
