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

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.... -
