If you know, which BIOS you had before, you could download this version and install it again. But there is no way to restore "your" old BIOS.

If you don't know, which BIOS you had, just use other versions than your current one (try and error).

Does this mean, that you have no output on you display at all, or is it only Windows that does not show up?

A BIOS-flash is always risky. If you see absolutely nothing, maybe a hardware reset can help you.

I'm not absolutely sure because a hardware-reset was not yet necessary on my notebook and I don't want to test it, as I made some changes in my BIOS.
But it is the standard way of doing a hardware-reset. And I can't imagine, why it should be different with the Si 1520 or the Li 1705.

@moon_shadow:
Do other Fn-combinations work? Maybe it is not the key-combination that doesn't work, but the display/graphics-chip that just isn't responding.


@Denys:
A hardware-reset restores the manufacturers settings of a working BIOS. But you seem not to have a working BIOS, I think this is the reason why the reset doesn't work.
On a desktop-PC I would recommend to exchange the BIOS-chip, but on a notebook it is not that easy.

A crashed BIOS normally cannot be restored by the user. I think you should contact the support and ask them what to do. Most likely they will ask you to send in the notebook and exchange the whole mainboard. A BIOS-update is not guaranty-compliant, so you will have to pay for it.

There are some descriptions of how to reflash a broken BIOS on the internet, but they are all quite complicated and success is unsure.
Until now I only flashed a few desktop-PCs without having any problems. So I can't really help you at this point.

I've just seen, that XP isn't officially supprted on the Li 1705.
Has the brightness-control worked with WinXP before you updated your BIOS?
Did you install any chipset drivers?
Is there a Keboard- or Launchmanager for other notebooks with your chipset?

Try another BIOS! I'm at my wit's end.
Maybe you can find out what was your original BIOS by searching for it in the internet with respect to the type of your notebook, date of acquisition and maybe other individual specifications.

Asking the support for your original BIOS-version should also be possible if you can specify the registration number of your notebook.
