Problems With Drives And Other Storage Devices; A Software Problem - Lenovo ThinkPad Edge E145 User Manual

– If the system status indicator (illuminated ThinkPad logo) is off, your computer is in power-off state or
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 return from sleep mode, your system might stop responding and you might not
be able to turn off the computer. In this case, you need to 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 4 seconds or more. If
the system is still not reset, remove the ac power adapter and the battery.
• 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 details, refer to "Power-saving modes" on page 28.

• Problem: The hard disk drive makes a rattling noise intermittently.
Solution: The rattling noise might be heard:

– When you carry your computer.
This is a normal characteristic of a hard disk drive and is not a defect.
