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:
Here is the IBM Lenovo T450s core i5 BIOS for this same model you require but there is a PW, if someone can clean it for us, it would be great!!! Thanks in advance
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.
Hello I loaded the bios that indicate here in my notebook but it asks me for a password when I turn it on, as a lock will you know which is the key and unlock?
