I managed to reverse the polarity on the DC input for my laptop (cheap travel power supply with adapters). Laptop went out, reboot via battery was possible and the laptop ran until the battery was dead.

My hope is that i just smoked a fuse or a diode protecting the mainboard itself. I took the laptop apart to take pictures of the DC input area.

I have some experience in soldering (little in SMD), have a multimeter and an oscilloscope to debug.

Ordering a new board doesn't make sense compared to the price of a new laptop.

Motherboard Model is 60NB04Y0-MBB030.

after fixing one of the hinges of my Asus Zenbook UX303LA-R4342H, while trying to plug the display cable back into the mainboard, I accidentally let the display cable touch the mainboard. This lead to a small flash of light and it smelled burnt. (I still had the battery pluggged in.) Now the display backlight does not turn on anymore. If I shine a light through the back of the display I can see the Desktop and also with an external monitor everything works fine.

What do you think broke? Is it the mainboard, the cable or the display? How can I figure out?

Unfortunately, I don’t have any other divices on which I could test the display.

I did not see exactly where the cable touched the mainboard - I only saw the spark in the corner of my eyes - but since the cable is relatively stiff and does not have a lot of reach I think it must have touched the mainboard to the left of the connector.

I already tried unplugging the battery and holding the power button for 30s as suggested on some backlight problem questions here, but this did not help.

Here is a picture of the mainboard:

And here is the output of the CPU-Z Utility:

Update:

I took the mainboard out the check the other side. I guess I found the source of the burnt smell. The burnt part is exactly on the other side of the display connector. There are also these two smaller things further above that also seem to have burned?

What are these broken parts? Is that something I could fix?

So I want to by a LCD cover replacement and swap my current display into it. If I wanted to remove the display from my broken LCD cover how would I do that?

There is no damage to the screen. But the screen does not stand since its broken. I need something to support it at the back for it to stand still.

How do I go about this? and where can i get it fixed?

Also, when pressing F9 during boot doesn't work on these laptops. Its supposed to display the hidden partition that will allow me to reset to factory defaults. Only option I can do is eventually get into Microsoft Advanced Options and reset the PC. However, it will only reset to 1803 update. So after a few reboots after resetting it, the same problem comes back. Someone please help!!

Thanks

It asks the enter password but it is not the password I usually use to sign in with. From what research I have done it appears I have to put in some sort of admin password (not the admin account tried that) or a password that came with the computer.

I no longer have to box or instruction manual stupidly threw it out and I appear to be lack of a serial number on the bottom of my laptop.

I have tried calling asus support but cannot get through.

I do not want to do a hard reset as I have documents I need to get to.

Also this is the actual computer I have (running windows 10) as I could not find it in the options

While i tried to fix some problems of a laptop, accidentally I broke the antenna of the NIC. The wire and the gold prong just broke off. I tried to reconnect putting the wire inside the gold prong and it seems right but, after that, the WiFi Signal is too weak. How can I fix this problem? There is some way to reconnect the gold prong and the wire?

Thanks!

My laptop had stopped charging although it was originally still recognizing the charger. The battery eventually drained completely and the laptop has never turned on from that point.

I believe I may have caused this issue as I had a power adapter that had gone bad (frayed wire) and I believe that to have caused a short somewhere in the laptop. I do have several chargers as my family owns several zenbooks in the same line and their chargers are identical. After the faulty charger caused the issue, other power adapters did not work either.

I brought the laptop to a professional to replace the power jack thinking that may fix the issue and now the laptop no longer recognizes any power connection at all. The bios has been reset and power up attempts have been made with the battery disconnected/re-connected. I also tried removing ram though some memory is still embedded into the board. A hard reset was attempted as well by holding the power button down for 30+ seconds. No luck :x

Are there other areas here I should be checking to troubleshoot? I would prefer not to have to replace the mother board here as they are rather expensive to replace for this model.

In doing some digging online I’ve read some Asus laptops have a “power chip” that could fry and keep a laptop from recognizing a charger, does this model contain a similar chip that could be causing this issue?

Open to any suggestions that may bring my laptop back to life

First, my laptop worked perfectly untill yesterday. Then I had the genius idea to try a USB key bootable linux. So I prepared my hard bootable key, gently put it in my usb slot.

Trying to make it work, I had to change a few parameters in the bios configuration menu (allow boot from non-verified source & select USB key as primary boot option).

Well... it didn't work. I did several trials so I don't remember exactly what I changed with the last one from a BIOS point of view. I selected "MBR for UEFI" in the making of the portable USB key with Rufus though.

Now, my laptop won't boot, and very worst, I cannot access the bios configuration menu. When I hit start, I see the Asus splashscreen indefinetely, and nothing (I have tried any key, but I used to press "delete" to access the configuration menu) seems to change that. The keyboard backlight flashes at the beginning for around 1s, then turns off. Then it stays with the asus logo for ever.

The only thing I have noticed is that when I press "escape" at the very beginning of the now-very-short boot sequence, the Asus splashscreens disappears for a beautiful black screen.

If you have any idea and are willing to share it with me, it would be super cool as my last option is now to throw the laptop against my backyard tree.

Thank you very much !

I have already upgraded the ram and it can only see 10 gp and upgraded SSD as well.

my question is, can I upgrade the CPU and GPU as well? Is it worthy?

thank you!

Could someone tell me the size of the screws for the ASUS Zenbook UX303L? I know the centre screws are shorter than the rest. I think I need the thread length, head thickness, head diamater and drive type.
