l'iMac si spegne improvvisamente

[d-force]

Salve a tutti, ho un iMac 27" 3,4 GHz Intel Core i7 16gb di ram.

Alcune volte usandolo con Bootcamp per fare un gioco con windows 7 il mac si spegne improvvisamente. Durante l'uso normale invece è tutto ok, ma con quel gioco, in particolare la sera, alcune volte si spegne all'improvviso.

E' possibile che il gioco assorba più risorse e quindi più corrente e un minimo abbassamento della tensione, l'imac si spenga?

La cosa, oltre ad essere fastidiosa (il mac poi non si può più accendere per qualche minuto...) ho paura che a lungo andare danneggi l'hard disk.

Cosa mi consigliate? Forse un gruppo di continuità?

Grazie in anticipo per il vostro aiuto!

Pare quasi più un problema di temperatura, nel senso che va in protezione per surriscaldamento. Mai provato a sentire quanto è caldo lo chassis quando si spegne di colpo?

Ciao Simone e grazie per la tua risposta.

Quando si spegne il mac è appena tiepido. Al massimo ogni tanto - durante il gioco - si sente andare la ventola.

Considera che il gioco è del 2011 quindi con requisiti di sistema inferiori a quelli del mio mac...

stesso problema. Risolto sostituendo alimentatore difettoso dell' imac

Ciao digit e grazie per il tuo contributo!

Ti si spegneva "random" o solo in particolari condizioni? (nel mio caso si spegne solamente durante uno specifico gioco. O almeno così mi sembra...)

L'alimentatore dell'iMac te lo hanno sostituito in garanzia? Se no, posso chiederti quanto hai speso?

Grazie ancora!

Era in garanzia.
Il mac si spegneva sopratutto durante L'utilizzo di finalcut,quando le risorse richiedevano maggiore utilizzo della CPU e conseguente consumo di energia.
Bastava mettere il mac a renderizzare per un po' e dopo circa una mezz'ora, 40 minuti si spegneva.
Ero costretto a staccare la spina della corrente x almeno 5 Minuti e poi reinserirla x poi accendere nuovamente il mac.

Prima di procedere a sostituire l'alimentatore, ho fatto un test relativo alla temperatura della cpu installando il software HWMonitor.

Durante il gioco incriminato la temperatura dei 4 core arriva a circa 88/89 gradi, o al massimo a 92 con conseguente avvio della ventola.

Ci sono altri parametri da tenere sotto controllo? Esempio, la temperatura dell'Hard disk mi sembrava nella norma...

Ad ogni modo, giocando durante il giorno l'iMac non si è spento. Le volte che mi è capitato era di sera... che voglia dire qualcosa? Farò nuovamente una prova di sera per vedere se si spegne di nuovo...

Che ne dite?

ciao. io ho lo stesso problema da un annetto.

imac late 2012
3,4 GHz Intel Core i7
8 GB DDR3 a 1600 MHz
NVIDIA GeForce GTX 675MX 1024 MB
Fusion drive 128 ssd + 1T


ho letto le 35 pagine sul forum di suporto apple
e tantissimi altri forum sullo stesso problema
qui un link con il problema
e con i link alle pagine ufficiali del forum apple sul problema
https://www.dpreview.com/forums/thread/3866995" onclick="window.open(this.href);return false;


in tutte si legge che il problema non si risolve nemmeno quando ad alcuni hanno sostituito:
alimentatore
scheda madre
scheda grafica
ram
hard disk

e il file log non rileva nessun errore.

essendo il mio imac non in garanzia, non vorrei iniziare a sostituire pezzi a casaccio, tanto pago io.
un po come fanno i meccanici.
ti cambiano tutto, alla fine però era una candela, ma poi ti dicono che tutto quello che hanno INUTILMENTE cambiato, stava rompendosi e cmq andava fatto.

il problema pare interessi solo quelli con i7 3.4ghz e i5 2.9ghz
potrebbe essere un sottodimensionamento e non un guasto dell'alimentatore.
infatti a molti a cui hanno cambiato l'alimentatore, il problema è rimasto.


Chiedo a chi ha risolto cambiando solo l'alimentatore:
il problema non si è piu ripresentato?
hai provato a fare un lungo rendering video e vedere se regge?

[ElBarto]

tenuto conto che la sostituzione dell'alimentatore potrebbe non essere la soluzione definitiva,
stavo iniziando a pensare a sostituirlo da me. online costa sui 60 euro.
all'assistenza apple mi hanno chiesto sui 250 per cambiarlo. mi sembra troppino....

le capacità x farlo non mi mancano.
spero solo di non incappare in problemi di sfiga + che di incapacità.

[tighine]

e il file log non rileva nessun errore.

Vediamo, insieme ad un report etrecheck.
E magari anche l'immagine dello specchietto utilizzo memoria di Monitoraggio attività (quello in basso), mentre stai renderizzando prma che si spenga.
