Hi, I have a Dell Vostro 2520. Somehow the insyde bios update failed an now it has only blackscreen following 3 beeps repeatedly. I already opened the laptop and thought I'd flash back the ROM content using hardware programmer but as I didn't find any specific service manuals I don't know how to identify the bios chip. Mainboard: DV15 MLK MB 11280-1 PWB MXRD2 Rev A00 IC: NPCE885PA0DX Found the (macronix) bios chip MX25L6406 which is located at the downside the mainboard from datasheet: http://forums.mydigitallife.net/attachment.php?attachmentid=32830&stc=1 cheers! best regards & a merry christmas holiday PS: unable to resize images!
