Many questions but not quite my problem

By DemDude1 ·
Dell Inspiron 1545 Laptop, works great with external monitor (laptop screen busted) except cant get into BIOS as external does not come on until the windows logo comes up. The question is two-fold is there a way to completely bypass the cracked screen so when I power up the external shows everything, or is there a command prompt i can use to get into BIOS after windows loads? Vista Home premium 32

Is the external monitor power on?

by seanferd In reply to Many questions but not qu ...

Or are you waiting for Windows to send it the power on signal? Make sure the monitor is fully powered on before booting.

Try pressing F2 repeatedly after you start the system, and see if this brings up BIOS setup on the monitor.

If not, time for a replacement laptop screen. BIOS is not accessible from the command prompt. Some vendors have an app to make BIOS settings available in the OS, but you'd already know if that app was in the Start Menu, and Dell doesn't do this at all as far as I know. The only method listed for entering BIOS on your system is F2 at POST.

Here it all depends if you have a Software or Hardware

Switch for the External Monitor.

If it's a Software Switch you need to have the Loaded OS part way running before it can switch to the external Monitor.

If you have a Hardware Switch then the Monitor Signal is switched by a switch and will remain connected to whichever monitor it was last used on.

Most NB's have a Software Switch so it's not possible to change the Default Monitor from the built in one.

You can however check the obvious thongs. Make sure that the external Monitor is switched on and warmed up before turning on the NB.

Enter the BIOS and see if there is an option to set the External Monitor to constantly on which may be more than a bit difficult here.

If your only option to enter the BIOS is to replace the Screen which is not uncommon with newer NB's then you may be stuffed quite a bit here. Though you could look for used Screens on places like E Bay and just wait till one becomes available cheaply enough for your needs.

But in answer to your questions:-

is there a way to completely bypass the cracked screen so when I power up the external shows everything,

Probably not but check the Dell Services Manual for this model here

or is there a command prompt i can use to get into BIOS after windows loads?

No there is no way to check the BIOS after the OS is loaded because these are completely different things. The BIOS is contained on a Integrated Circuit on the M'Board and the OS is loaded onto the HDD and load and runs from that. There is currently no way to use a Loaded OS to access the BIOS.
