Der Akku wurde ohne Probleme erkannt, das W520 lief auf Akku, aber das Laden bei gestecktem Netzteil erfolgte nicht. Seitenzahlen beziehen sich auf den Stromlaufplan des W520. Alle Messungen koennen ohne CPU erfolgen, da die Ladung des Akku allein vom EC gesteuert wird.<br /> Es muss aber ein Akku gesteckt sein, damit Pin 1 von U55 aktiviert wird.<br /> <br /> == Fehlersuche ==<br /> Das Laden wird vom IC U55, ein BQ24742, gesteuert (Seite 74). Damit dieser laedt, muessen das Signal MPWRG aktiv sein, ausserdem noch eines der Signale BAT_CRG, S_TRCL oder M_TRCL. Zudem muss -EC_RESET inaktiv sein. Dann hat der Pin 1 von U55 HIGH Pegel.<br /> <br /> In vorliegenden Fall waren BAT_CRG und MPWRG aktiv, -EC_RESET war inaktiv. Trotzdem lag an Pin 1 LOW an.<br /> Im ausgeschalteten Zustand mass ich ueber R588 einen Widerstand von weniger als 40 Ohm gegen Masse. Bei einem T420 Board mit derselben Schaltung waren es knapp 10kOhm.<br /> <br /> == Reparatur ==<br /> Ich vermutete, dass der Pin 1 von U55 defekt ist und tauschte den IC gegen denjenigen aus dem T420. Dazu braucht man eine Heissluftstation, da der IC als QFN vorliegt, mit einem grossen Massepad unter dem Chip. Vorsicht mit dem Lautsprecherstecker und dem Tastaturanschluss, diesen sollten mit Kaptan-Band oder Alu-Folie abgedeckt werden, damit sie sich nicht verformen. Nach dem Ausloeten des alten U55 sollte man zur Kontrolle noch einmal ueber R588 messen, dann sollten dort knapp 10k zu sehen sein.<br /> <br /> Nach dem &quot;Aufloeten&quot; des Austausch-IC mit Heissluft hatte ich erst mal den Fehler &quot;0190 critical low battery&quot; im Betrieb mit dem Netzteil. Vermutlich war Pin 13 (EXTPWR) nicht verbunden und die externe Spannung wurde nicht korrekt erkannt. Deshalb loetete ich die Pins an den vier Seiten nach.<br /> <br /> Ausserdem entfernte ich R586 (1kOhm) und setzte stattdessen dort R588 (10kOhm) ein. Das Datenblatt des BQ24742 schreibt einen Serienwiderstand von 10k vor, wenn CE auf High einer anderen Spannungsversorgung als Vref gelegt wird. Pin 1 hat intern einen Pulldown (1M).<br /> <br /> == Ergebnis ==<br /> Das W520 laedt wieder. Ob der Fehler im U55 durch den zu geringen Serienwiderstand hervorgerufen wurde, weiss ich nicht.<br /> Da die Schaltung bei T520 und T420 identisch ist, kann man analog eine solche Reparatur versuchen.</div>
