I know the bios is good, so your problem is elsewhere. Check all power 19V, 5VALW ,3VALW

EDIT: What bios programmer are you using.

When I install this bios in my notebook it asks me for a password to be able to enter the bios, they will know what it is, thank you ..

Lenovo ThinkPad T450s -BIOS Fix

Hello guys, hope your all fine!

Need some help, i have one Lenovo ThinkPad T450s
Board Model:
AIMT1 NM-A301 REV 1.0

Well, machine seems to power on, but only gives me a full black screen no backlight, no caps no num lock on internal or external keyboard.

I measure some points on LVDS connector i have the 3.3V and 20V.
LID Switch seems ok, 3.3V and when i put magnet on him drops to 0V so it's fine.

I talked with some people and all they say me BIOS Issue, i have original dump attached for anyone who could open it search for any error and fix the dump for me please.

Thanks for all any questions please be free to post.

Lenovo T450s BIOS Signature

First thread. Anyway, I've modded my bios to replace the date/time menu with the advanced menu but now the T450s has 2x5 beeps at every cold and warm boot. I'm told this is because the signature needs to be modified. Is this possible on this laptop or not? I'm on the latest bios version 1.37

I've been pointed in this direction reading all of this post:

https://www.insanelymac.com/forum/to...eps-on-lenovo/

But of course my BIOS is different and the steps need to be modified which I'm having trouble with. Anyone know what I'm after?

I'm a bit reserved paying someone to do it because who knows what edits they'll make to the bios without my knowledge.

Thanks
