I have an asus n53j (first gen i5, nvidia gt425m) that initially would not turn on at all, and on the one occasion it did work it froze in bios after about 30 seconds. I had the random idea to solder a 470uF cap near the cpu as there were a large amount of blank spaces for capacitors and the system now boots reliably and is rather bullrtproof. However, if an intensive task is run for more than ~2 minutes, be it a game like skyrim or something like 3dmark or prime95, the laptop will randomly shut down and refuse to start for about 30 mins (as if something is cooling down) and then will work normally. It is not the cpu or gpu as under all conditions they idle at around 80 degrees max. Tested the ram and it seems fine too. The results from the capacitor lead me to believe it is a power related issue as there are a few FET's missing from thr board and a few unpopulated capacitor pads.

Re: asus n53j weird problem.
u did not remove the bad cap so there are some problems -
Re: asus n53j weird problem.
Most caps are tantulum, from what i understand they dont exactly go bad, plus, its more like something is heating up and going out on some kind of thermal shutdown, and if they do go bad they generally do so in quite a visible wayAttached FilesLast edited by luke10050; 10-30-2014, 08:38 PM.Comment

Re: asus n53j weird problem.
Not always. I'd change all tantalum caps around the cpu.Comment

Re: asus n53j weird problem.
Okay, i'll give it a go then, might also see if i can get a thermal camera... depends on my luckComment

Full name/ Model: Asus Zephyrus M16 / GU603ZW-M16.I93070T
CPU: Core i9-12900H
Onboard 8GB DDR5 4xMT60B1G16HC-48B:A
Problem: This laptop was brought to the shop with the board already meddled with. Last technician (maybe without the right tools) removed an electrolytic capacitor (PCE9203) sensing resistor (PRS9801) and probably flashed both BIOS (U2802) and VBIOS(U7802).
The laptop's behavior is: When connected, it tries to power up. CPU powers on, and (allegedly) the power sequence finishes and goes to S0 (PLT_RST = 3.3V). It consumes 600mA, ramps up to 1.100 A and... -
Hello,
I have a problem with the bios, let me explain.
With BIOS 1, the pc takes +- 30 seconds to display the ASUS logo (black screen) and to boot.
I did a clear ME, my black screen problem for 30 seconds at boot is solved, it gives me directly the display and boots quickly.
My problem is that now, once the charger is plugged in and I put a slight load on the processor, it bogs down to 0.39GHz...
The only solution is to unplug the charger to get the cpu back up to speed. But as soon as I plug in the charger, it goes straight back down.... -
Asus Vivobook X515JA Laptop
Issue :
Upon turning laptop ON, screen lights up - stays black & about 30+ minutes later ASUS logo is shown & boots to windows, then laptop works fine.
Tried :
Cleaned inside for dust, applied fresh thermal paste. No Change!
Removed keyboard, Trackpad, fingerprint sensor. No Change!
Removed Internal SSD. No Change!
Updated BIOS to latest version. No Change!
Removed battery and pressing power button for 1 minute. No Change!
Weird Part :
Upon turning laptop ON, screen lights up - stays black,

Hi. I bought a damaged Asus motherboard, model dabkxmb18b0 rev.b. The problem with the motherboard was a faulty processor.
I replaced the processor, but it arrived without a BIOS chip. I found one post on the forum, but my problem is
I don't know which chip to program, and I don't have a schematic. Does anyone know which BIOS chip models are compatible with this motherboard? If so, please let me know. Thanks. -
Hello everyone,
I’m trying to recover an ASUS TUF Gaming A17 FA707NUR (Ryzen + RTX 4050, 2023 model).
The laptop powers on, fans spin, but the dGPU (NVIDIA) is not properly initialized — sometimes it shows up in Device Manager with Code 43, sometimes black screen.
After several BIOS downgrades/upgrades (versions 300, 301, 303) and EC resets, it thinking looks like the EC firmware (IT5570VG-256) might have a persistent fault or flag stored in flash.
I already extracted the BIOS .CAP files and DXE sections with UEFITool and IFRExtractor, but I couldn’t find...
