Blank screen on Toshiba Laptop

Which specific model of Acer 710 do you have? Some have a Windows OS and others have Google Chrome.

Try a single left click of the mouse. On Windows 8 systems, the default setup is to show a picture on the lock screen on booting. The single click leads to the login screen. (Depending on the settings, you log in with your MS username and password or a local account. Microsoft recommends the MS account. You can add a picture password, as well. That's a pattern password relative to the picture.)

I hope this helps.

Hi,

Please restart in the safe mode once.And run a virus scan after that turn off your laptop and turn it on again now don't go into the safe mode just start the windows normally,enter your password and see if you face the same problem.

You may have a corrupt driver, so go to my computer, right click>properties>hardware tab>device manager, then look at the list for mice and other pointing devices, click on the '+' sign and and then your touch pad will be listed, right click on it and select uninstal. Restart the pc and it will automatically reinstall and should work as normal

Either the cable that runs from the screen tot he motherboard is loose/broken or your video chipset on the motherboard has dry solder joints.

is it a windows password or poweron password? you must be wondering what are they?
windows password is when you have to enter the password to get into windows and before that you get to see the windows loading screen.
poweron password is hard to crack, it will ask a password on a black screen saying Enter a Password, and the background will be completely black in color.
if its a windows password, press the "Alt+Ctrl+Del" twice, you'll get a screen which will ask you a username and password. in the username and password type in, "Administrator" and password will be blank. hit enter. if it works, then for the rest of the steps, mail me at [email protected]

The BIOS password is removed by the BIOS configuration, you need the BIOS password to get into the BIOS configuration.But if you do not have the BIOS password then you need to construct this dongle device.
TOSHIBA BIOS PASSWORD DONGLE
You can build a dongle that plugs into the printer port.Purchase a 25 pin male D sub connector and solder insulated wires to the various pins as listed below. The pins are numbered on the connector
http://www.tilman.de/sonstiges/toshiba/dongle1.jpg this is a picture of the finished dongle


Wire the pins as follows :-1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15
Plug the finished dongle in the printer port and power up the laptop. The password will be reset, go into the BIOS configuration to check the BIOS password, you may have to disable the BIOS password.

If it's at bootup:

You need to temporarily remote the CMOS battery from the motherboard to reset the bootup password.

If it's at login:

If the screen went blank after the driver install, sometimes clicking the mouse on the screen will bring the picture back. It sounds like the monitor is having a conflict with the resolution the driver is throwing out. Reboot the laptop and when you see the Toshiba splash screen, tap F8 until you see the multiple boot menu. Scroll to Safe Mode with networking and reboot. If the screen comes up, go to the control panel > System > hardware > display adapter > click on the plus sign and double click the reported adapter.click on driver tab and select roll back driver > click yes to any prompts and click ok. Reboot normally and see if that clears the problem.
