This video shows how to troubleshoot
your notebook using Windows 8 when it
starts but the screen remains
blank. Follow these steps if your
notebook computer turns on but the
screen remains
blank. A hard reset can resolve many
issues that cause a blank screen.
First, press the power button to turn
off the
notebook. Disconnect all devices from
the notebook. Remove any USB devices and
media
cards. Disconnect the AC power
adapter and remove the battery.
Press and hold the power button for at
least 15
seconds. Reconnect the AC adapter, but
do not connect the
battery. Press the power button to turn
on the notebook. If the screen turns on,
the issue is resolved. If the screen is
still blank, continue to the next step.
The screen might remain blank if there
is a problem with the LCD
display. Test the display by connecting
an external
monitor. If you're having trouble
viewing the external monitor, press the
F4 key to switch between the screens.
If an image displays on the external
monitor, there might be a graphics
driver conflict with the notebook's LCD
display. With the external monitor
connected, go to
support.hp.com and click on the software
and drivers tab to download and install
the latest drivers for your computer. If
the screen is still blank, continue to
the next
step. Many HP notebooks have an
emergency BIOS recovery feature that
allows you to recover and install the
last known good version of the BIOS from
the hard
drive. Follow these steps to recover an
earlier version of the BIOS. You will
not be able to see anything on the
monitor.
Press the power button to turn off the
notebook. Plug the notebook into a power
source using the AC power
adapter. Press and hold the Windows key
and the B key at the same time while the
notebook is
off. While pressing the Windows and B
keys, hold down the power button for 1
second. Then release the power button
and the
keys. The power LED light remains on and
the screen remains blank for about 40
seconds. The BIOS update begins. If the
screen is still blank, continue to the
next
step. Removing and replacing the memory
modules might resolve blank screen
issues. Follow these steps to remove the
module, then place it back in the memory
slot.
Open your internet browser and go to
support.hp.com. Type your model number
and replace memory into the HP support
page search field to find steps specific
for your computer
model. Follow these steps to drain all
the power from the notebook to prevent
accidental damage to the electrical
components.
Turn off the notebook by pressing and
holding the power button for 30
seconds. Unplug the AC adapter from the
notebook. Slide and hold the battery
release latch to unlock the
battery. Lift the battery
out. Loosen the screws on the memory
compartment cover. Then lift up and
remove it.
Pull the retention clips away from the
sides of the memory module. Then pull
the module out of the
slot. Do not touch the metal contacts.
To prevent damage to the memory module,
grasp the memory modules from the edges.
Hold the memory module at a 45° angle
and align the notched edge of the module
with the tab in the slot. Firmly press
the module into the
slot. Pivot the top edge of the memory
module downward until the retention
clips snap into
place. Then place the cover over the
memory compartment and tighten the
screws.
Plug the AC adapter back into the
notebook. Then connect the AC adapter to
a working power
supply. While the computer is off, place
the battery into the base enclosure and
press until the retention clips click
into
position. Power on your notebook and
check to see if Windows loads.
If the computer fails to boot to the
Windows desktop after trying all steps,
contact HP to find out your support
options. Your options for service might
vary depending on how long you have
owned the computer and what country you
live in.
