Hello, i bought eight E4251, one for my father and others for work. My father's pc stopped powering on after some months, before that, it worked well. It seemed like the battery was gone, but did not power on even with power cable plugged. I succeeded in powering it on after some try of reset and holding power button. I don't know how. But now it works. Its battery was full when I powered it on, so it was not a problem of battery low. Really unusual. Yesterday, two PC of mine did the same. But I cannot succeed on powering them on. If I push power button they don't light any led. If I keep pressing nothing happens (tried for 30 and then 60 seconds - nothing). If I reset them with the little hole backwards, then when I press Power button they light the led for about 2 seconds, then turn off, then light again for less thano a second, then die and if I press again they won't turn on. The same if plugged or unplugged (it's about 6 hours one is plugged, it is not a problem of power (tried with many ppower supplies that work with other 6 pc). Any idea? Maybe it's RAM broken and it tries to power than go to protection?
