Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

Thanks, I'll find another spot and post the picture. If it goes into hibernation or sleep mode now, I can't get the computer to turn back on heheh

Still, this is a lot better than Chassis Intruded: Fatal Error...

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

I see you pulled 3.3v from a resistor. Maybe that's part of some other circuit and it takes a little while to charge. Try finding a capacitor with 3.3v on it, that should charge up quickly (as it'll be directly across a 3.3v regulator) and it should work on a cold boot as well.

The capacitors are the brown colored parts with no marking on them.

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

This helped me fix my Asus P5E deluxe. It also had the Chassis Intruded fatal error. Took me only a few seconds to find the right transistor, thanks to the directions.

It's not perfect yet. Is it possible that my 3.3v point comes on too late? If I do a cold boot it gives me the error, but when I reset everything is fine.

Anyway, I wanted to say thanks and give people looking for a solution for their P5E deluxe some directions. So I added a picture of the fix for the P5E deluxe. The transistor is located in the bottom left corner of the motherboard. Underneath the winbond chip.

That's for sure, that PSU wires have higher resistance than traces on mobo....

I don't see how "too good of caps" would cause a problem either. The PSU's wires have enough resistance so that the PSU never really "sees" the low ESR of those "too good caps" on the motherboard.

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

too good of caps?

Nice thread, but I see lot of Panasonic's FJ caps...
If there are at the rear USB connectors, I would replace them with Rubycon XYG 8x11 1000uF, even used ones are good for that place...

Reason for replacement - too good caps (??), on wrong place ...

To add, through time, inductive, capacitive, or even resistive bond is created, and is main cause of that behavior...
Most likely some caps died, and can not swallow current... And because they're FJ's - most likely PSU caps took big hit...

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

I think I'll cheeck back for the BIOS fix mentioned...

If you're waiting for *me* to fix the BIOS, i won't.

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

My friend has an ASUS P5-N32 Sli Deluxe board with the same problem. He can't make any changes in BIOS and save them, because on the next restart the chassis intrusion message pop's up. So no overclocking could be done. We tried everything from flashing the BIOS, replacing all the jumpers etc, nothing helped.
Wish I could find this 7-8 years ago, when it was brand new. It cost around 250-300 euros.

Thanks for the explanation.

Thanks for this post. I received my first Chassis Intruded ! alert this morning. I think I'll cheeck back for the BIOS fix mentioned...

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

Found a bigger one on the 'net. Check all SOT-23 transistors in the circled area, one of them must be the chassis intrusion detector. There's only 6 of them so it should be easy to find.

I could probably learn the knowledge required to patch the BIOS in a few weeks (i've done this before), but my time is very limited nowadays, and also, i don't have such a board to test.

Thanksssssssssssssssssss

If you could get me some guidelines - BIOS... since you studied this in past.

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

Yes this could also be solved thru BIOS modification, but disassembly of a BIOS ROM is beyond my software skills. If you show me a clear, high resolution photo of your board, i could point out where you can check to find that transistor.

Thank you for your quick answer.

If we solve in BIOS, many P5K owners ... appreciate this.

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

Hi,

This problem is very common in Asus site and in many forums in Internet.

Since I crack many software - Mac and W$n ... I would like your advice and expertise to solve this in the BIOS.

Disassemble BIOS - the ROM code and change the jump ... in the code. Not in Menu


Anyone test this procedure - Transistor in P5K E

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

Neat fix!
If only I knew of this fix a few years ago. Someone gave my friend this exact same motherboard since it wasn't working. And because no one could fix it, it just got torn apart for random parts.

IMO, ASUS motherboard can be real stupid sometimes. I have an older AsRock S939 motherboard designed by ASUS (at least that's what it looks like), and one of the regulators for the RAM Vcc gets so hot that the PCB has severely darkened around it. And this is not limited to just my motherboard model. I've seen other ASUS boards with this problem as well.

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

If you would have actually read my explanation of the issue, you would have noticed that...



That's right - i'm not "just turning the intrusion detection off" because it cannot be turned off. Trust me, i've looked everywhere in the BIOS setup (and manual too) of that board, the option to turn it off or ignore it is missing.

Oh.

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

good work! while I've never had this problem from an Asus (one of the few quirks I havent had from 'ass backward asus'), thanks for sharing this fix!

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

Why don't you just turn the intrusion detection off? Every board with it that I've seen has that option.

If you would have actually read my explanation of the issue, you would have noticed that...

On most other boards that support a chassis intrusion sensor (switch), there is an option in the BIOS to change the chassis intrusion sensor so that it merely reports that your case has been opened, rather than preventing you to boot up the damn computer. There is no such option with ASUS boards. The mere inclusion of this feature would have prevented all this trouble.
