After updating bios no display

If the issue is not resolved by performing a hard reset, proceed to the next troubleshooting step.

Step 2: Connecting an external monitor to test the display The notebook screen display might remain black when there is a corrupted graphics driver or a problem with the LCD display back light.

If your computer beeps and does not start, a more serious hardware issue is likely occurring.

recently I did a bios update on my laptop (Lenovo z50-75) and it had to shut down to install so it did and when I went to turn It on it was just a black screen I could hear the fan and everything starting up but no display.

Due to large amount of what APPEARS to be failed flashes (most people I'm sure RMA'd because of this) there is a simple fix to get it back in working order.

If this method does not work for you, then blind flashing is your next option. During the process of blind flashing and prior to flashing, we were at the selection of boot devices (flash drive in this case) and we originally down arrowed twice to select the flash drive and had no success after the command line was initiated and time patiently waiting before restarting.

If you cannot find a memory replacement procedure for your computer module, review the User Guide.

If you can hear sounds of operation but no image is visible on either display, proceed to the next troubleshooting step.

Step 3: Recovering the notebook BIOS using a key press combination When you upgrade the BIOS on your notebook, a copy of the previous BIOS version is stored in the HP_TOOLS partition of your hard drive.

You don't want to encourage people to be flashing their BIOS in the first place, unless their is a need to do so.

In which case they will post their problem here and we can assist them when that time comes with a write-up if we feel a BIOS update will address the issue in question.

You may need to press the Fn Key - one to the left of the spacebar - and probably F6 to switch the display to the external source.

I have to thank The Voice for everything they've done for me.
