Hello everyone, I have this DELL computer. problem when turning on it does not show an image. Diagnostic LED indicates CMOS battery failure. I measure the battery and 3v is fine. When turned on with battery CMOS consumption of 240mA. By removing the CMOS battery it can consume 800mA and sometimes gives an image when it wants. This happened after a while of installing an SSD. Will ME be corrupted by Windows?

Has anyone had a similar Dell model happen to them? The rtc_soc part was checked and it is at 3v, that is, rtc power is on, and also rtc_det# remains at a high level, because although these signals are there, it does not detect the bios battery. At D1 the cathode output is approximately 3v. The diagnostic LED flashes 3 amber and 1 white. According to the Dell manual, it says it is a CMOS battery failure.
