      Re: advent dead ish

      There are a few basic things to try. I'm just a noob around here so they'll be simple things.

      1. Are the clicks that you hear from the hard drive? If Yes, See if it will boot past bios without the hard drive.
      2. If there are 2 sticks of RAM, remove one stick of RAM and see if it will boot with the other stick. If not, try the other stick of RAM.
      3. See if it will boot on battery alone (without AC charger) if not see if it will boot on AC charger (without battery).
      4. Remove all power including CMOS battery. Leave for 5 minutes and reassemble and try again.

      I think what you describe could be a bad bios but could also be lots of other things too. Further tests would depend how confident you are about taking the laptop apart, for instance to try another processor. good luck.

          hi
          yes the click is from the hard drive if you mean boot using f2 to get in to bios then no it won't theres no sign of screen life. will not boot from battery alone or AC alone i removed the CMOS as said and still nothing ???

              I had a hard drive clicking when a computer was dropped (pretty bad, the screen cracked) and the hard drive was damaged in fall. It would still read partially, but i thought the clicking was when it tried to access some sectors it could not.

              Anyway, did you try booting it with another hard drive? You can also try to pull the hard drive and connect it to a working computer via usb, if you have the right cable (I use xbox data transfer cable)

                No. I mean taking the hard drive out and starting the laptop to see if you get as far as a pxe/media error.

                    Without any power source plugged in (power suply and battery) hold down the power button for 60 seconds. After that connect power supply and try again.

                        Try removing ram stick by stick and attempt to boot. If no luck then replace with some borrowed known working ram and try again.

                        Then do the same with the processor If no luck with the ram.

                        If none of that works your next step would be a bios re-program. How to do that will depend on your laptop brand and if you have access to a bios programmer.

                        If that doesn't work you're looking at chasing voltages and you'll need someone smarter than me to help you with that.

                            It may be bad solder at the power jack...
