okay so hello and in this video we are going to take a look at uh how to repair the or not repair uh good luck with repairing one how to replace the cmos battery also called the clock battery the rtc battery the bios battery whatever you call it we're going to replace it in this presario 1200 series laptop and i believe that this also more or less applies for a 1000 series laptop and so first i suppose we should start with symptoms so with the 1200 series you'll usually get uh yeah do a seek test and it might take longer to post than usual and you'll get a couple of beeps and it'll say something like real time clock air as this one does uh the i'll let you in a little secret some of the 1000 series and possibly other models will actually throw a different error code that says system board failure the system board has not failed and i've actually scored a laptop on the cheap that was doi
