Model: Lenovo Legion 5 Pro
Describe the issue: I have installed new window drivers and enabled dGPU in Legion Vantage and when asked to reboot, I did. Now when i try to turn on my laptop i get stuck on a blank screen
What have you tried already?: Taking the nvme out and put it back in, unplug battery for 5, holding all fn keys I found, FN + 2,8,9,del, etc, external monitor
When did it start producing the issue: After reboot
Did you install new drivers or software?: Drivers

Ill pay someone 10$ crypto pls help me lmao

the hard is alot of work right?

cinder heart
gentle hazel
#

yes

#

did you do blind bios for your gen?

#

so laptop is bootable and it shows rgb? it just doesnt show anything on screen?

cinder heart
#

yea

#

lemme try the blind bios 1 more time

#

i think i pressed the wrong buttons

gentle hazel
#

it says dGPU to iGPU so make sure

#

you are doing the correct one

#

and ofc, for correct gen

cinder heart
#

i think i got the wrong gen

#

the up and down beeped

#

how do i find out which gen i am?

gentle hazel
#

your laptop model number?

cinder heart
#

15ARH7H

gentle hazel
#

so gen 7

cinder heart
#

well i did this

#

nothing

#

thats for g7

gentle hazel
#

interesting, i guess you have to wait a bit more sadly

cinder heart
#

for?

gentle hazel
#

for someone to help you

cinder heart
#

ahh

gentle hazel
#

did you spam F2 for 20s?

cinder heart
#

oh my

#

yea

#

lemme try 1 more time

gentle hazel
#

i am not doubting anything

#

you just rushed through every possible solution

#

and nothing works so

cinder heart
#

is it normal that my laptop beeps when i press the up and down keys?

gentle hazel
#

cant recall, dont have machine with me sadly

cinder heart
#

should i just take the whole laptop apart for that battery

#

u think it would do anything?

gentle hazel
#

there is slight chance

cinder heart
#

u think i should transfer the nvme to my main pc

#

reinstall

#

windows then tyr?

#

or not going to do anything

gentle hazel
#

that wont help

cinder heart
#

so cmos is the best idea?

gentle hazel
#

currently, along with blind BIOS which I still have no idea how it doesnt work for you

cinder heart
#

well i tried the blind bios wit a hdmi plugged in and this time it didnt beep?

idle tangle
#

the issue may not be related to gpu, you got new bios update through windows updates and it became bricked or something, gen7 recently got bios update

#

but take this with a grain of salt

#

it can be the dgpu

cinder heart
#

i dont liike that word bricked

#

what can i do to fix it?

idle tangle
#

what does the device do when you click power button

cinder heart
#

keyboard turns on

#

few secs leter

#

later

#

the screen turns on but its like black

#

its on but blank

idle tangle
#

ah

gentle hazel
#

can you like

idle tangle
#

then yeah bios isnt bricked

gentle hazel
#

flash it with a flashlight?

cinder heart
idle tangle
#

no way it is that issue extralaugh

gentle hazel
#

just read the message

#

and do what it says

idle tangle
# cinder heart wdym by that

there is some infamous bug that makes your screen so dimm that you cant see shit on it. kinda works if you point another light source through the leds extralaugh

cinder heart
#

ahh

#

sec lemme try

#

and no

gentle hazel
#

ah

#

sadge

idle tangle
#

so F2 doesnt work ?

#

still black screen ?

gentle hazel
#

you didnt spam F2?

cinder heart
#

nope

idle tangle
#

MAN

cinder heart
#

i spammed f2 many times

idle tangle
#

ah

#

f

gentle hazel
#

ok

#

so far not working

  1. EC soft
  2. Blind BIOS
  3. flashing with flashlight with F2 spam
#

i am without any idea rn

cinder heart
#

real question...

is FN+Q reacting?
and is FN+Space changin keyboard lighting?

idle tangle
#

anyway you can try blind bios, hit f2, wait for screen to lit and try navigating

bios_a.png
cinder heart
#

fn q no fn space yes

#

OK, the OS/windows is not started then...
not a backlight issue

cinder heart
#

it had a delayed beep tho

gentle hazel
#

i cant recall a beep

#

when does it happen

cinder heart
#

usually after pressing any arrow key

gentle hazel
#

huh

cinder heart
#

uh oh shit kinda died on me

#

sec

cinder heart
cinder heart
cinder heart
cinder heart
#

no beeps

#

nothing really happened

#

lemme try 12 sec

#

nothing after 12 too

#

should a hdmi cable be plugged in?

#

don't think it matter...

#

just checking are you on AC?

#

whats ac?

cinder heart
cinder heart
#

rn it is

#

i noticed this idk if it matters but

#

before spamming for bios and doing that blind bios

#

and i press the power button

#

it doesnt turn off instantly

gentle hazel
#

it technically shouldnt

cinder heart
#

normal;

#

no idea, sorry

#

you think i should take the cmos out?

#

you can give a try, disconnecting both battery, but don't get too hopefull

#

where are the dgpu settings stored

#

what if i just clean that

manic grove
#

You have a password set in the bios because mine beeps in the arrow keys before putting the password

cinder heart
#

oh shit

#

u are right

gentle hazel
#

no way

cinder heart
#

LMAO

#

woops

gentle hazel
#

maybe you should have mentioned that

cinder heart
#

i forgot bout that

gentle hazel
#

doesnt matter

#

its okay

cinder heart
#

all i need to do is just enter pass and press enter?

gentle hazel
#

yes

manic grove
#

Disconnect battery and chmos dosent reset mux

cinder heart
#

well i did the blind bios and still nothing

#

how can ik if i put the right password or anything

manic grove
#

Press arrow key and dosent beep

#

Oh just press shift and one key bios doesn’t accept capitalize letters

#

Press 2 times enter because if fail will apear a message saying is the wrong password

cinder heart
#

im confuised now

#

what are the exact steps i should take

#

boot up

#

spam f2 for 20 secs

#

press shift

#

write pass

#

enter 2x

#

then up down enter esc enter?

manic grove
cinder heart
#

it does

#

what does that mean

manic grove
#

Nice do the rest

cinder heart
#

enter 1 or 2?

manic grove
manic grove
#

And verify if beeps again using shift+letter

#

If dosent beep just do the blind bios

cinder heart
#

blind bios not doing much

#

the power button is instant turn off

#

that means it is still in bios?

manic grove
#

Yes

cinder heart
#

is that good or no?

#

i stillk have the same screen on but blank

#

what am i supposed to do now

manic grove
#

Yes is good you can acess the bios

#

By the way you have a usb-c to hdmi adapter?

cinder heart
#

that idk

#

second

manic grove
#

One of usb-c port can output the bios to the display i think

cinder heart
#

yea idk bout that one

#

that is a weird cable

#

or a newer type cable

#

and i dont have that

#

do i need it?

manic grove
#

No

#

Try do the blind bios until get the password right

cinder heart
#

to make sure i got the password right i just press shift + any key

#

and if it doesnt beep

#

im in?

cinder heart
#

but nothing working

manic grove
#

Strange it should just work

#

But the laptop restarts when you end the blind bios
