Resumen:
After the detection of more than 40 symbiotic stars in X-rays,  they are now recognized as a significant X-rays population. Their high energy emission allow us to unveil the accretion mechanism onto the WD and we are starting to estimate what is their main source of power, i.e. accretion versus nuclear burning. Our observational program aimed to detect X-rays using different satellites such as Suzaku, Chandra, XMM-Newton and Swift indicates that X-ray emitting symbiotics are accretion and burning-powered in about equal proportions. At  the same time, our program is allowing us to uncover a previously unknown population of hard X-ray emitting symbiotics. In this talk, I will review our main results and comment ontheir likelihood of symbiotics to become SNIa  progenitors.
