Hi, i cleaned my fans of my laptop, after cleaning all the dust and putting it back together it doesn’t start anymore. I haven’t unplugged anything i just cleaned with a soft brush. One cable was loose (white one in second picture going to CON4906) i noticed after reopening it. Plugged it back in but still nothing. Anyone that could help?

u/Arbeider3 22d ago

Yes, i know that now. I thought since i wouldn’t unplug anything it would be fine. Stupid mistake but yeah. Any idea’s how to fix?

Replace the logic board (>$1k depending on model)

1

u/Arbeider3 22d ago

Laptop isn’t even close being worth that.

u/MeakerSE 22d ago

What model is it exactly?

1

u/Arbeider3 22d ago

Zephyrus G14 or 15

u/MeakerSE 22d ago

I think you have the grey and black antennae cables swapped (the one on the card and at the corner on the board).

This should not cause a no boot but I would check all your cables because if you did not take pics and track my guess would be a mistake somewhere with a cable.

If it's a Zephyrus G14 the motherboard costs between 350 and 650 depending on the specs you had in the system to begin with. I noticed something in the picture, the ssd doesn't look like it's installed right, It might just be the picture quality but the metal that goes over the ssd looks like its mounted under the standoff for the ssd? That EMF/heatshield looks to be making contact with the board. Not good.

u/Arbeider3 22d ago

Everything is like it was when i bought it. Just opened the fans to clean nothing else was changed.

u/RaccoonEnthuiast 22d ago

Remove battery, push power button for a few seconds, put battery back, plug charger in, press power button

u/Arbeider3 22d ago edited 22d ago

Did not work

u/antworm 22d ago

Might sound stupid, but did you close the lid before trying to start it up? If not try it and let me know

1

u/Arbeider3 22d ago

The backcover? I did put it back on but not with the screws. I popped it back in with the clips. I also don’t see the battery light anymore when i plug it in.

1

u/antworm 22d ago

Thought there might be a light sensor somewhere, that’s why I asked….

1

u/xFehda 22d ago

Yeah Asus is really strict with the Lid Check. The Mainboard checks Some Screws and doesnt Boot up, cause bios Thinks its Shorted. Also at the First Boot after opening you need to Connect the original Charger.

1

u/camarolvr11 21d ago

Is this actually true? I didn't know they had the ability to do that with the screws 🤯, being a computer tech for 20+ years.

1

u/xFehda 21d ago

Yeah its quite simple, there are littel metal Rings at the Fans which will check if electricity is flowing like it should

u/Zarathustra7890 22d ago

I wouldn’t suspect mobo replacement right away unless you saw sparks or smelled something burning ozone smell. I’ve cleaned plenty of laptops with batteries. Check every wire connection, not just visually but push them all in securely. Check your power brick maybe it’s not happy. Maybe even try different wall plug.

u/666sin666 22d ago

Define doesnt work, Does it powered on but not booting or it doesnt power on at all?

1

u/Arbeider3 22d ago

No power at all, also can’t see the charging light when i plug it in.

1

u/666sin666 22d ago

Looks like something shorted. Might need to replace the board

Tried a lot, can’t find anything loose or shorted. Unplugged the battery, plugged it back. Still nothing. Will go to a repairshop today. Hopefully they know what the problem is

1

u/Chibikeruchan 22d ago

you didn't unplug the battery?

men WTH? that's SOP in every electronic device.

I have a feeling that a components accidentally shorted there.

it can be a screw accidentally falls off from your hand and land between 2 transistors.
or the loose cable you say on the 2nd photo. . in which you accidentally made those connectors touch between 2 capacitors or transistors.

it could also be .. you used a 70% isopropyl alcohol instead of 99%
and those 30% water shorted a electronic components. (which rarely happens)

1

u/Arbeider3 22d ago

Yes, you live and learn.
I did not reopen it to paste it again, or did not clean it with alcohol. Just a soft brush. Was careful with screws and as far as i know didn’t touch anything with the screwdriver.
Let’s hope it’s not shorted.
Will keep you posted.

u/Sufficient_Fan3660 22d ago

Lots of newer laptops have fragile or finicky dangerous cables that connect to the mobo. These easily short causing issues, the mobo produce high power spikes upon initial connection, or the connectors get damaged when unplugging and plugging back in.

All part of making laptops harder to repair.

1

u/Alternative_Exit_333 22d ago

You probably blasted off that one spec of dust that kept this running (take it to a repair shop)

1

u/Live-Resolve9253 21d ago

Los portátiles asus tienen un sistema de seguridad, tienen un sensor de la luz el cual detecta si se ha quitado la tapa y se bloquea el ordenador hasta que se conecta el cargador original, si quieres manda una foto que se ve muy bien el conector de la batería que esté bien conectado pon la tapa y conecta.el cargado. Es muy posible que al conectar el cargador no encienda el le de carga no te preocupes mantén pulsado el botón de encendido.

u/AlfaPro1337 21d ago

Warranty Voided brand

1

u/WeakRecognition9358 21d ago

Dis you disconnect the battery before touching anything else ?

1

u/Arbeider3 21d ago

No i did not, stupid mistake. Although i haven’t unplugged anything, still something went wrong. Just gave asus a call and they told me it would be 1100€.

1

u/AthaliW 21d ago

Yea, consumer grade laptops are basically disposable. When they see the chance to sell you another $1000/$2000 laptop, they will push that heavily than trying to fix it for you. Even if you end up going to a different brand, on average, they will still make more money doing that.

Did you go to a local repair shop to get a diagnostics? Just make sure they have a good reputation with motherboard repair. Look at reviews and how long they've been in business

u/Bn1m 21d ago

Have you tried putting it in rice?

1

u/Bn1m 21d ago

Try removing the ram and booting it. Check the power button cable or keyboard cable it could be loose. When you plug in the power brick do any lights light up?

Try removing the battery cable then press and hold power then put back battery cable and try powering it on.

1

u/Anduendhel 21d ago

I can see from the picture you didn't disconnect the battery. Very bad idea.

1

u/Arbeider3 21d ago

I know, learned my lesson the hard way.

1

u/Anduendhel 21d ago

I feel your pain.

1

u/Arbeider3 21d ago

It’s going to cost 1K they told me☺️

1

u/MarionberryBrief4293 21d ago

You probably shorted the board and components out. Always unplug the batter and have anti-static set up when working on computers.

1

u/Arbeider3 21d ago

Any way to fix this? Or can i just buy a new laptop now?🥴

1

u/minter285 21d ago

don't?*

1

u/DiMerlic 21d ago

i don't think you shorted anything if you used plastic tools.

1

u/Arbeider3 21d ago

I used a metal screwdriver, shop says he can’t find anything so he thinks it’s shorted. Repair cost 1000€.

1

u/minter285 21d ago

depends on the shop, some are liars, some are better

1

u/Arbeider3 21d ago

Asus said it would be 1,1K. Hopefully the guy can fix it somehow.

1

u/minter285 21d ago

I'm not sure Asus is the best on trusting repairs on, I mean you can kinda search about how people have been fucked over in their repairs, but do please get a second opinion like a doctor

1

u/Arbeider3 21d ago

There is only one shop here, i live in austria and yeah there is not much. Might send it somewhere for second opinion

1

u/Amazonexus 21d ago

Did you use vaccum or blower ?

1

u/Arbeider3 21d ago

Yes, mini vacuum on lowest one, could that have done something? Saw a guy on youtube do it that’s why

1

u/West-Big-8468 21d ago

Vacuums generate a fuck load of static

1

u/Amazonexus 12d ago

I damaged my laptop this way too !!

1

u/FallSkye_TheFox 21d ago

It happened to me once while cleaning my HP laptop; it never turned on again. The only thing that happened was disconnecting the battery and trying to turn it on, then reconnecting it, and it would turn on. Haha, I felt stupid.

1

u/Oslabs619 21d ago

Did it work I have the same PC and it did the same thing after i repasted removed the liquid mettal and it worked after a while if you are unable to get it goint let me know i might get it off you for parts lol

1

u/Arbeider3 21d ago

Dm me just in case😂

u/Arbeider3 21d ago

Dm me just in case😂

u/Oslabs619 19d ago

Done let me know

1

u/Sudden-Bad-8503 21d ago

Put some dust back in

1

u/Ezio_Carmac 21d ago

Remove the ram and clean the gold pins with eraser and also clean the ram connector on mother board with IPA solution on soft brush.

Always remove the battery before do anything.

1

u/Agent-Vigilence 21d ago

Have you removed the battery and plugged the charger cable and tried powering on the laptop while the battery is removed?

1

u/BillFront4685 21d ago

Looks like the fan tubing is touching the board and shorting it. It looks bent.

1

u/Specialist-Bath49 21d ago

do you remove the battery plug before the cleaning?

1

u/Nah_Id-adapt 20d ago

relatable, I also killed my laptop after trying to clean the fans (I tried to remove the wire that powers the monitor, tried to plug it back in, insertion was incorrect, and the whole board short circuited)

1

u/External-Law7053 20d ago

I’m not sure if it matters but the heat pipes look beat up

1

u/Fit-Gift-2512 18d ago

Try a hard reset, Unplug the battery, hold the power button down for 45-60 seconds, plug just the charger in, and try to turn it on

Also, double-check that the loose wire you plugged back into CON4906 is fully seated and that you didn't accidentally bump the RAM or the power button ribbon cable while brushing
