Q: WallStreet 12" death, maybe a overvoltage ?

Hello, I am new on the forum

When I connect my WallStreet (I do not have a battery) the ventilator starts to do much noise, and the small green indicator ignites.
The screen does not ignite.
The diodes of locking keyboard do not work.
It does not make noise with starting.


I think that it is perhaps because of an overvoltage.
I also dismounted WallStreet. Which are the parts blamed at your opinion?

Thank you and sorry for my bad English

iMac G5 Mac OS X (10.3.9)

    I had not seen this subject : http://discussions.apple.com/thread.jspa?threadID=732831&tstart=0, I am afflicted, apparently it is exactly the same problem. But this topic has been archived and I have a other question : why the chart processor would broken? And which are the precautions to take to handle it?

    The fan running non-stop tells you ONLY that:

    1) power has been interrupted AND
    2) The internal backup battery was not strong enough to maintain the internal parameters to avoid corruption, so all the parameters may be wrong.

    There may be nothing permanently wrong.

    If sleep LED is continually on, backup battery power has been interrupted. Restart computer by holding down Shift-FN-Control and Power-on key. Wait 5 seconds and press Power-on key. If computer doesn’t restart, repeat 3–4 times.

    leave it connected to the charger. It can take 48 hours on the charger to get a dead backup battery back in operating range.

    Thank you for your answer, I am reassured a little. Indeed the sleep LED is continually one. I tried to make 4 reset like you say, but that does not do anything. I will leave the computer connected during 48 hours.
    Does it have to be only connected ? Or ventilators, and the LED must be on ?

    It is connected in hopes of recharging the small internal backup battery. Fan/ventilator on or off and LED on or off make no difference.

    Usually, but not always, Reset turns the fan and LED off.

    Yes, it's the situation with my WallStreet, it's the reason why I ask this question .It has been connected for this morning (in France 13 or 14 hours) and still nothing ... I wait ...

    toniomac,

    This was a response from another user who had the same problem and asked for help from PB Parts:

    "The light and fan staying on after a PM reset indicate that the PMU is asking to be reprogrammed, but is getting no response from the processor. In their experience, my symptoms indicate a bad processor about 70% of the time, a bad logic board about 20% of the time, and all other causes, including an iffy PMU, the remaining 10% of the time."

    The above user had success replacing his microprocessor card. You might consider buying another Wallstreet for parts (it might even have a dead display) and then start swapping parts. The other approach is to spend $60(?) for a diagnosis, then replace the part yourself.

    OK, I will try to seek another PB or of the parts.

    Somebody who has the same problem said to me that it had to start PB without keyboard, and that had gone. Is this a stroke of luck ? That did not go with me ...

    toniomac,

    A bad keyboard can prevent the Wallstreet from starting. If you wish, carefully disconnect the keyboard ribbon cable from the logic board, then try starting. I doubt this is your problem, but certainly worth a try.

    Here is a disassembly guide:

    I don't know that a bad keyboard can prevent the Wallstreet from starting. Indeed it did not start.
    If I disconnect the keyboard, and that I connect one in ADB, it will be able to start ?

    toniomac,

    You don't need a keyboard to start the Wallstreet. Just disconnect the Wallsteet's keyboard ribbon cable, then press the power button. If it starts, I believe you have to remove all power to turn it off; I don't think pressing/holding the power button will shut down the Wallstreet like newer powerbooks.

    Yes, that did not change anything, I continue to seek a new chart processor

    hey,

    I bought a new chart. It arrived today.
    But no, chance, I replaced it and that do not do anything...
    Is it possible that a broken part makes roasted all the processors ?

    Which are in general the other parts blamed in my case ? (in the 10%)

    Thank you

    toniomac,

    Besides the microprocessor card, there are three other possible components. Below are the parts and examples of each. Please don't put a lot of money in this 12" Wallstreet; it doesn't have much value and troubleshooting a failure by replacing parts can be expensive. (I am guessing it is a 12.1" passive-matrix, dual-scan display with the 233MHz/0k CPU.)
