- In the Boot menu in BIOS setup utility, make sure that the hard disk drive is included in the EFI/Boot device priority correctly.

A startup problem

The Microsoft ^® Windows operating system does not start.

- Use the OneKey Recovery system to restore the system partition to its original status or a previously created backup point. For details about the OneKey Recovery system, see "Lenovo OneKey Recovery system" on page 27.

A backup problem

Backup cannot be made.

• You are not currently using a Windows operating system.
• There is not enough space to store the backed-up data. You will need to free more space on the destination device.

Other problems

Your computer does not respond.

The computer does not start from a device you want.

The connected external device does not work.

• To turn off your computer, press and hold the power button for 4 seconds or more. If the computer still does not respond, remove the AC adapter and the battery.
• Your computer might lock when it enters sleep mode during a communication operation. Disable the sleep timer when you are working on the network.
• See the Boot menu of the BIOS setup utility. Make sure that the EFI/Boot device priority in the BIOS setup utility is set so that the computer starts from the device you want.
• Press the Novo button when the computer is powered off and select Boot Device Menu. Then select the device you want the computer to start from.
• Do not connect or disconnect any external device cables other than USB while the computer power is on; otherwise, you might damage your computer.
• When using a high power consumption external devices such as an external USB optical disk drive, use external device power adapter. Otherwise, the device may not be recognized, or system shut down may result.

Note:

• The illustrations used in this chapter are of the Lenovo IdeaPad N580, unless otherwise stated.
• The following procedures about removing and replacing devices are the same for the Lenovo IdeaPad P580/P585/N580/N581/N585/N586.

Replacing the battery

Note: Use only the battery provided by Lenovo. Any other battery could ignite or explode.

To replace the battery, do the following:

① Turn off the computer. Disconnect the AC adapter and all cables from the computer.
② Close the computer display, and turn the computer over.
③ Unlock the manual battery latch 1 Holding the spring-loaded battery latch in the unlocked position 2 remove the battery pack in the direction shown by the arrow 3

4 Install a fully charged battery.
⑤ Slide the manual battery latch to the locked position.
6 Turn the computer over again. Connect the AC adapter and the cables to the computer again.

Replacing the hard disk drive

You can increase the storage capacity of your computer by replacing the hard disk drive with one of greater capacity. You can purchase a new hard disk drive from your reseller or Lenovo marketing representative.

Note:

• Replace the hard disk drive only if you upgrade it or have it repaired. The connectors and bay of the hard disk drive were not designed for frequent changes, or drive swapping.
• The preinstalled softwares are not included on an optional hard disk drive.

Handling a hard disk drive

• Do not drop the drive or subject it to physical shocks. Put the drive on a material, such as soft cloth, that absorbs the physical shock.
• Do not apply pressure to the cover of the drive.
• Do not touch the connector.

The drive is very sensitive. Incorrect handling can cause damage and permanent loss of data on the hard disk. Before removing the hard disk drive, make a backup copy of all the information on the hard disk, and then turn the computer off. Never remove the drive while the system is operating or in sleep mode.

Appendix A. CRU instructions

To replace the hard disk drive, do the following:

① Turn off the computer; then disconnect the AC adapter and all cables from the computer.

② Close the computer display, and then turn the computer over.

③ Remove the battery pack.

8 Remove the screws and detach the metal frame from the hard disk drive.
9 Attach the metal frame to a new hard disk drive and tighten the screws.
10 Put the hard disk drive gently into the hard disk drive bay with the tab facing upwards and the connectors facing each other; then push it firmly into space.

⑪ Reinstall the frame fixing screws.
12 After aligning the attachment clips with their matching gaps, reinstall the compartment cover.
⑬ Reinstall and tighten the screws.
14 Reinstall the battery pack.
15 Turn the computer over again. Connect the AC adapter and the cables to the computer again.

Replacing memory

You can increase the amount of memory in your computer by installing a double-data-rate three synchronous dynamic random access memory (DDR3 SDRAM)-available as an option-in the memory slot of your computer. DDR3 SDRAMs are available in various capacities.

Note:

• Use only the memory types supported by your computer. If you incorrectly install optional memory, or install an unsupported memory type, a warning beep will sound when you try to start the computer.
• Select models of the computer may have only one memory slot. Refer to the actual product. However, the procedure for replacing the memory is the same as listed below.

To install a DDR3 SDRAM, do the following:

① Touch a metal table or a grounded metal object to reduce any static electricity in your body, which could damage the DDR3 SDRAM. Do not touch the contact edge of the DDR3 SDRAM.
② Turn off the computer. Disconnect the AC adapter and all cables from the computer.
③ Close the computer display, and turn the computer over.
④ Remove the battery again.
⑤ Remove the Optical drive/Hard disk drive (HDD)/Memory/CPU (Central processing unit)/Mini PCI Express Card slot compartment cover.

6 If two DDR3 SDRAMs are already installed in the memory slot, remove one of them to make room for the new one by pressing out on the latches on both edges of the socket at the same time. Be sure to save the old DDR3 SDRAM for future use.

⑦ Align the notch of the DDR3 SDRAM with the protrusion of the socket and gently insert the DDR3 SDRAM into the socket at a 30-45° angle.

Appendix A. CRU instructions

⑧ Push the DDR3 SDRAM inward toward the socket until the latches on both edges of the socket are pushed into the closed position.

⑨ After aligning the attachment clips with their matching gaps, reinstall the compartment cover.
10 Reinstall and tighten the screws.
⑪ Reinstall the battery.
⑫ Turn the computer over again. Connect the AC adapter and the cables to the computer again.

Note: If only one DDR3 SDRAM is used on the computer you are servicing, the card must be installed in SLOT-0 (lower slot), but not in SLOT-1 (upper slot).

To make sure that the DDR3 SDRAM is installed correctly, do as follows:

① Turn the computer on.
② Hold F2 during startup. The BIOS setup utility screen opens. The System Memory item shows the total amount of memory installed in your computer.
