• Problem: The computer does not resume from sleep mode, or the system status indicator blinks slowly
and the computer does not work.
Solution: If the system does not resume from sleep mode, it might have entered sleep or hibernation
mode automatically because the battery is depleted. Check the system status indicator.
– If the system status indicator blinks slowly, your computer is in sleep mode. Connect the ac power
adapter to the computer; then press Fn.
– If the system status indicator is off, your computer has no power or is in hibernation mode. Connect the
ac power adapter to the computer; then press the power button to resume operation.
If the system still does not resume from sleep mode, your system might stop responding and you might
not be able to turn off the computer. In this case, you must reset the computer. If you have not saved your
data, it might be lost. To reset the computer, press and hold the power button for four seconds or more.
• Problem: Your computer does not enter sleep or hibernation mode.
Solution: Check whether any option has been selected to disable your computer from entering sleep or
hibernation mode.
If your computer tries to enter sleep mode but the request is rejected, the device attached to the USB
connector might have been disabled. If this occurs, do a hot-unplug-and-plug operation for the USB
device.
• Problem: The battery discharges slightly while the computer is in hibernation mode.
Solution: If the wakeup function is enabled, the computer consumes a small amount of power. This is not
a defect. For more information, see "Power-saving modes" on page 22.

Hard disk drive problems

• Problem: The hard disk drive makes a rattling noise intermittently.
Solution: The rattling noise might be heard:
– When the hard disk drive begins or finishes getting access to data
– When you carry the hard disk drive
– When you carry your computer
This is a normal characteristic of a hard disk drive and is not a defect.
• Problem: The hard disk drive does not work.
Solution: On the Startup menu of ThinkPad Setup, ensure that the hard disk drive is on the Boot priority
order list. If it is on the Excluded from boot order list, it is disabled. Select the entry for it on the list and
press Shift+1 to move it back to the Boot priority order list.
• Problem: After I have set a hard disk password, I move the hard disk drive to another computer but
cannot unlock the hard disk password on the new computer.
Solution: Your computer supports an enhanced password algorithm. Computers older than yours might
not support such a security function.

Solid-state drive problem

Problem: When you compress files or folders by use of the data compression function in the Windows
operating system, and then decompress them, the process of writing to or reading from the files or folders is
slow.
Solution: Apply the disk defragmentation tool in the Windows operating system for faster access to the data.
