Lenovo ThinkPad W700ds Troubleshooting Manual page 27

Problem:
When I turn on the machine, only a white cursor appears on a blank screen.
Solution:
Note: If you have modified a partition on your HDD or SSD by using a
partition software, information about that partition, or the master boot
record, may have been destroyed.
1. Turn off the computer, and then turn it on again.
2. If you still see only the cursor on the screen, do the following:
v If you have used the partition software, examine the partition on the
HDD or SSD by using the software, and recover the partition if
required.
v Use either the Rescue and Recovery workspace or the recovery discs to
restore the system to the factory state.
For details about restoring the system to the factory state, see
Chapter 4, "Recovery options," on page 35.
3. If the problem persists, have the computer serviced.
Problem:
The screen goes blank while the computer is on.
Solution:
Your screen saver or power management may be enabled.
Do either of the following:
v Move the TrackPoint or press a key to exit the screen saver.
v Press the power switch to resume from sleep (standby) or hibernation.
Problem:
The computer does not respond.
Solution:
1. Turn off the computer by pressing and holding the power switch for 4
seconds or more.
2. If the computer still does not respond, remove and reinstall the AC
adapter and the battery.
Your computer might lock when it enters sleep (standby) mode during a
communication operation. Disable the sleep (standby) timer when you are
working on the network.
