      Just a quick update.

      I switched on the laptop for the 1st time since Sunday and started in safe mode with no networking as advised. The screen looked just like image 4 above.

      I’ll try an external monitor tomorrow.

        99.99% sure that it is hardware related then

          I was just logging in to reply regarding the external monitor test. I only had around 30 seconds before the laptop did the blue screen of death. However, when connected to the external monitor, the display was just the same as the attached images.

          It looks like the default display setting was to duplicate the laptop screen - would that have had an influence on this test? i.e. would the true test have been to switch to the β€œextend display” setting? Or does that not matter?

            It shouldn’t make any difference tbh, try extend if you wish but can I just mention that in your screenshot one the lines are present before Windows or any other software has loaded so the problem is hardware related.

              Thanks phillpower2.

              Is it possible to determine at this stage whether it is worth investing more time and effort to resolve the issue?

                Cleaning the inside of the notebook, checking out the internal cooling fan and removing/reseating the RAM are three things that can be done, are you prepared to undertake the task/s.

                [COLOR=rgb(41, 105, 176)]NB: When you tried the external display, did you try it on battery power only and then removing the battery and using just the AC adaptor.[/COLOR]

                  Ordinarily I’d be up for trying the tasks, I’m just short on free time just now and I’m going on holiday soon too. I’m happy to try once I get back.

                  I only tried the external monitor when using the AC adaptor with the battery plugged in.

                  As a side note, I think the battery is dead and doesn’t hold a charge.

                  Thanks.

                    If the battery has any charge, try the external screen while on battery only and then AC adaptor only and battery removed, alternatively, remove the battery and just try AC adaptor only, we are checking to see if this could be a power issue as in over voltage or a short circuit.

                    If you let us know what date you will be back of your hols we can mark your thread as pending until you return, the alternative is to close and then re-open it when you are ready, we don`t like to leave open threads hanging in case other folk start posting in them.

                            Thanks for opening the thread again.

                            I have cleaned out the fans (there was a lot of fluff/dust in the cooling fins) and removed and re-seated the RAM. At present I’m still seeing a blank screen when powering on.

                            I have tried connecting to an external monitor with the laptop powered by battery only, AC power only, and battery + AC power.

                            For all cases, the laptop screen powered on but was blank and the external monitor showed a screen of green dashes.

                            Thanks.

                              Not a good sign I`m afraid

                              Can I ask how many sticks of RAM you have, hoping that it is two so that you can try one stick at a time in each of the memory slots to see if that changes anything.

                                There are 2 sticks of RAM. I will try as you have suggested and report back.

                                Thanks.
