Peculiar laptop problem

  DrScott 08:20 13 Apr 2006

I've developed a rather odd problem on my laptop which Google seems unable to solve. Essentially when I turn my laptop on I am unable to see anything on the screen, and cannot access the bios. However, the computer still continues to boot into Windows XP normally, and at that point the screen works and everything is hunky dory! I can't work out why the screen does not work on boot, but will run through windows just fine?!

Does anyone have any ideas?

Probably a "silly" answer, but do you have a "brightness" control (a physical knob to adjust the level) that could have been turned down to minimum but whose setting is subsequently overridden once Windows has booted?

  DrScott 09:16 13 Apr 2006

No such thing as a silly answer. Well that's what I was always told at school!

The laptop is an Acer Travelmate 800 series - Intel Pentium M / Centrino setup - about 3 years old now. It doesn't have a physical brightness control, but one that is accessed by pressing Fn and then the relevant brightness button. Makes no difference.

I have an Acer laptop and during boot up it displays a default 'ACER' screen, I wonder if that has been deleted, moved, or corrupted?

I'm sorry but I've no idea how to check this.

Just a thought?

No Acer screen. The computer must be POST-ing okay because it continues to Windows XP.

Boot to BIOS (F1, F2, or CTRL+ALT+ESC for acer machines)

disable the Acer splash screen it is written to BIOS on a lot of laptops

Thanks, but that's kind of the whole point! I can't any sort of picture or screen on the initial boot sequence, so I can't boot to the bios! It's a blank screen right up until windows XP kicks in... it's very strange.

Acer screen, is built into the BIOS so BIOS must be corrupt. Well that's how I see it.

I say this as Acer and others do have custom BIOS's created

Is there anyway of altering the Bios from windows?

Try pressing (F1, F2, or CTRL+ALT+ESC for acer machines) as it boots, it should bypass the splash screen and boot into BIOS which you should beable to see.

Noway of getting to BIOS from windows.

BIOS can be reset to default values by removing CMOS battery for 10 mins or so.

I did try those combinations, but to no avail. I'll give it another go later - having tried pressing delete in the past, I suspect it may have entered the Bios but I couldn't see anything. Anyway, I'll try again and see what happens.
