Model: Lenovo Legion 5 Pro (16ARH7H)
Describe the issue: Black screen when i try to turn it on, the the led from the power button turns on but there is no output from the screen (keyboard is off but that's because i always have it off)
What have you tried already?: Tried many things that i saw online like holding the power button for 60 seconds, also win + ctrl + shift + b, and tried blindly going to the bios to reset it or switch the gpu modes (i had it on Switching mode when it was working) but nothing worked
When did it start producing the issue: laptop is 4 days old, everything was working perfectly till yesterday night i pulled it out from my backpack when i came home and the issue happened. But i did notice when it first happened the power button led went blue AKA in quiet mode (like i normaly have) but after turning it off and trying the various fixes it was always white
Did you install new drivers or software?: i didn't

#

Forgot to add that hooking it up to an external monitor has no output still

worthy gale
#

did the power button turn white?

spice flicker
#

Ye unplugged everything

#

Then i plugged the charger and turned it on and was still black, i tried it multiple times spogebob

#

did u do any updates"?

spice flicker
#

Now that i think off ye, there was that new windows 11 update, but i was using it after it and was working fine, it's when i came home few hours later that it was dead hmm

#

This yesterday

worthy gale
#

did u do any bios updates?

spice flicker
#

Yes, but that was when i first got it, which was on friday

#

With lenovo vantage

worthy gale
#

uhoh

spice flicker
worthy gale
#

try CMOS reset, but taht involves u to open up the laptop

#

but

spice flicker
#

Ye i was thinking to try that yesterday

worthy gale
#

wait let some knowledgeable dude come here cuz u dont want it to get messy

spice flicker
#

I can add that when i turn it on the leds for the caps lock and num pad don't turn on at all if this gives any clues hmm

worthy gale
#

looks like u gotta do a CMOS reset

spice flicker
worthy gale
#

@lament python dont u think he gotta do a cmos reset

lament python
#

Are your fans doing anything when the power button light is on?

#

Do you hear anything from them

spice flicker
#

Nothing

lament python
#

same as it happened to me

#

in January

#

I had the very same problem just like you

spice flicker
lament python
#

fans off, power button lit and the charging lid from the back of the laptop

#

nothing else worked

#

I had to send it to warranty and they decided to change the motherboard(GPU being dead)

#

Do you remember what did the BIOS update say when you installed it?

#

can you tell me some numbers

#

53WW?

#

GKCN53WW, something like this?

spice flicker
#

Oof i don't remember

lament python
#

GKCN57WW

#

I don't think CMOS reset would help if fans are completely dead...

#

but can try since nothing else left to do

#

other than RMA

worthy gale
lament python
#

I personally got a black screen in cyberpunk as I was going through the settings

#

immediately downgraded to 49WW

spice flicker
#

JUCN51WW maybe this one i had, not sure, but lenovo shows this as last for 16ARH7H

#

Kinda weird my laptop died in the meantime i was coming back home, was working fine when i was at uni few hours before

lament python
#

Were you on the laptop and it suddenly went black?

#

in front of you?

spice flicker
#

No

lament python
#

ah

#

nvm

#

but still very similar case

#

to mine

spice flicker
#

I took it out from my backpack, turned it on and black screen

lament python
worthy gale
#

did u drop ur bag or sm?

lament python
#

This was my issue

worthy gale
spice flicker
lament python
#

Yes, I did

#

They swapped the motherboard

#

took about 11 days

worthy gale
#

ohh

lament python
#

and mine wasn't due to some bios update

#

I was on 44WW until 2 days ago

#

for almost a year

#

so no "53WW" situation

#

@spice flicker do you have good Lenovo support in your country?

#

Sadly, very unfortunate case to see...after just 4 days

#

They will most likely replace the motherboard and send it back to you(if you don't have some policy to get a brand new laptop instead)

spice flicker
#

I'm from italy, there is no lenovo center near me to send it, only 3rd parties

worthy gale
#

uhoh

lament python
#

F

worthy gale
#

maybe return?

lament python
#

Where is your warranty related to?

#

any idea?

spice flicker
lament python
#

2 years is default, unless you have premium

#

afaik

spice flicker
#

I'll just call them later and see what i can do i guess, thx for the support

lament python
#

and I think 1 year in US

lament python
#

By actual EC reset, I meant:
To hold power button for 30 secs until the pc shuts down and also gives a sound while its off, dont release the key until that sound comes after its turned off
then remove back panel, remove battery and CMOS
Now Reconnect CMOS without battery and switch on the laptop with ac adaptor and run the laptop for 5 mins
then shut down the laptop and reconnect the battery
now switch on the laptop and check if your issue has been resolved

spice flicker
#

Can't try rn, but i know for sure it didn't do any sounds when holding the power button for 30 or 60s

lament python
#

That sound is not mandatory, as far as I'm aware. Not everyone hears it even when they tried to do it so.

spice flicker
#

Nice

lament python
#

I think this is the number

#

I do not understand what it says so

#

They also contact you mid-website but I do think it's a bot

spice flicker
#

Thanks

spice flicker
#

Defo dead, tried connecting external mouse and keyboard and they don't turn on at all Wojackmeme_cryFacePalm

worthy gale
#

😢

#

cant do anything else

#

RMA it/return

#

tried CMOS reset?

lament python
#

Mine at least died after 3 months

#

Tbh, I became extremely paranoid after mine died, refused to use AMD driver from main website, refusing to use Legion Fan Control, Legion Toolkit, etc

#

Took me few good months to actually realize none of these were at fault

#

and it was just a faulty unit

worthy gale
#

my ideapad mobo died

#

and now u said 3 months

#

and im scared

spice flicker
lament python
lament python
#

it was just me being paranoid after that shit happened

worthy gale
#

no not being sarcastic

lament python
#

these things have 0 effect

worthy gale
#

cuz my ideapad motherboard fried itiself too

#

and its lenovo

#

so im scared if my legion gonna fry

lament python
#

Well, take my case as example

#

after RMA and mobo replacement

#

it's been rock solid since January

#

0 issues

#

And there are people that had no problems, as you can see

worthy gale
#

hmmm

#

yeh ur right

#

cuz mine is now turning 3 months old

lament python
#

Bro, there's no curse that after 3 months all die lmao

#

I know a person with similar situation to acszo's

#

in the other legion server

#

a girl had problems with her legion 7 motherboard dying like this

#

I think 2 times afaik

#

after 1 week

spice flicker
#

Bouta be me when i get it fixed

lament python
#

Look at the good side, you are still under warranty

#

because motherboard replacement outside warranty is just a ticket to shoot yourself

#

since it costs a lot

lament python
#

What kind of problem are we talking about? At least give a hint. If you don't want to then yeah, go ahead.

#

I'm sorry, I tried to delete that as I realized I needed to post my own thread.

#

Ended up deleting just one of two posts

lament python
#

Oh, np

spice flicker
#

update: they're sending me a new one, have to say the italian support for lenovo is lil sussy

lament python
#

A new laptop completely? Damn

#

That's better than getting a motherboard replacement, as long as you did not lose any super important data

spice flicker
#

Just gna be a pain doing the whole setup again when i did it few days ago

lament python
#

All the best wishes in the world for this other one to just run fine and you to have a pleasing experience with it! It sucks to start everything from scratch but the feel that the laptop you got is new and not some "attempt"of repair they might have done there is safer.

spice flicker
#

Ye this laptop cracked MyMan, hopefully new one doesn't troll waitinforthegirlslike

Hi.
I just bought a Legion 5 Pro 16IAH7H i7 12700h and RTX3070 1 TB SSD 32 Gigs of ram.

For some reason the VGA crashes randomly.
Not when it is under stress, the laptop can run DOOM Eternal at 280+ fps, but I limit the fps to 60 in Nvidia control panel.
Same with Warhammer 3 and Mechwarrior 5, etc.
All of my games are locked to 60 fps max and I only play at 1980x1200 resolution.
BTW the crash came also before I made these changes.

Sometimes it appears when the laptop is turned on for a long time and only windows is running, nothing else.

It cannot be a thermal issue cause I have a cooling pads Spirit of Gamer 1000.

When this issue appears in games the screen became black and the mouse are glitching (plus not moving) and some parts in the screen have green blinking glitches. Like a usual VGA crash.
With windows the whole screen turns black and only the mouse is visible and glitching (still not moving).

In both case noting can help or work, and I have to press the power button to force the laptop for a forced restart.

I have tried to update the firmware and all driver from the official Lenovo site, but I till have the issue.
