      What are the silk screened markings on the logic board?

      Can you post pictures?

      Without ram, do you hear any post beep codes? Any blinking led pattern to note that the ram is missing?

                  VRef_DQ =PIN 1
                  VTT/Termination voltage=PIN 203,204
                  VRef_CA. =PIN 126
                  VDD SPD =PIN 199
                  SDA data =PIN 200
                  SCL clock =PIN 202
                  DRAM_RST# =PIN 30

                      Do a clean me region or flash a new BIOS, that's the first thing you should do

                          HP Elitebook 8560p - sudden power off
                          by blazzelia
                          Hi guys,

                          I have an HP Elitebook 8560p which works for a while, then suddenly powers off.
                          I check the MB and I found a small cap exploded near a 6912 MOSFET (there were 3 such caps in parallel). I replace it with a 2 uF cap and the interval of power off events increased a lot. Initially the laptop was stopping at, in average, every 15-20 minutes, now it works for hours but it still stops once or twice per day.
                          I also replaced the 6912 MOSFET but it did not made any difference.
                          Unfortunately I don't have and could not find a schematic for this laptop so I'm...

                          nm-c171 rev:1.0 s145-ast backlight proplem
                          by sonerpc
                          On the s145-ast lenovo laptop with nm-c171 rev:1.0 motherboard, the image appears without illumination. When I look carefully, I can see the lenovo text. I downloaded the bordviewer and the schematic from the badcaps family, but which voltages should I measure? 20 volts come out from both ends of the fuse.

                          The problem with this motherboard model is the video card. When the video card driver is installed, the device freezes. Is there a possibility to cancel the video card in this motherboard model. Or is there a software that will cancel my external video card via bios?
