Black screen after bios screen

[hingo1983]

Might be a long shot here but with laptops there is a function where you can set the output of the VGA port. This can usually be set in three ways:

1) Laptop LCD Monitor + external VGA Display
2) Laptop LCD Monitor - external VGA Display
3) No Laptop LCD monitor display + external VGA display

To cycle through these settings, its usually a matter of holding down the Fn key and pressing the appropriate function key. In my experiences, this key is mostly the F7 key but it depends on brand and model.

If it seems to boot to windows but has no display, then this may be your problem. If not, then try to boot it from CD and run a memory test or HDD test.

So do you see the POST screen? Or do you only see the manafacaturers logo?

If you dont see the POST screen then there is something seriously wrong. Same as actually getting into the BIOS. But if you can see the POST screen then you should be able to see the BIOS screen. The POST and BIOS screens on laptops are designed to work whatever the display setting is (like kingo1983 said). If the BIOS is screwed there is not much to do except claim it under warranty if it is. If the BIOS fails then it's usually not work fixing because the BIOS is a chip sitting on the motherboard!

could be faulty memory new versions of windows wont tell you if its bluescreened, it will just hang. get a bootable cd (bart PE or something) and run a memcheck

make sure the boot order is correct too
