Guest tyc Posted March 4, 2012 Share Posted March 4, 2012 O memorie care e de fapt un regulator LDO...de 5V. http://www.alldatasheet.com/datasheet-p ... S2501.html Poti sa simulezi integratul printr-o sursa de tensiune cu tranzistor serie. Link to comment
Guest comanas Posted March 4, 2012 Share Posted March 4, 2012 am incercat mai mult de atat cu o sursa reglabila am bagat diverse tensiuni dar nu-l vede se pare ca e vorba de un eprom care descarca niste date de recunoastere ,inlocuirea cu unul nou necesitand programare,multumesc pt raspuns. http://www.chzsoft.de/storage/2501unw.pdf Link to comment

mely17 Posted October 10, 2013 Share Posted October 10, 2013 Buna ziua. Am o problema cu un dell inspirion 6000 la care un "meserias" suspectand ca ar fi cablu de vina la schimbat cu altul, doar ca pinul de data la legat la + si a bagat 19V pe pinul acela. Intrebarea mea este ca afectat cu ceva laptopul sau memoria DS 2501? Dupa ce am pus cablu cum trebe nu se incarca. Link to comment
