Hi follow your great channel and have a tricky Laptop problem that as a repairer myself , i cant quite nail. and love some help.. Problem is the usual "wont start and blank screen- but for months sometimes start good and most not- intermittent!!! worst fault haha OK- What it isnt- I have switched out ram and PS and its not over heating ect as i service it but that would be once it s hot and OH. I have also change SD HD with another and fresh windows install so its not windows or t the HD!! Problem-- Push button (3 volts ok?) and power light and mouse comes on but nothing on screen OR 'windows starting" but then nothing. So kill power a couple of times and after 1-4 tries, into windows and DESKTOP and if that far NO failure or blue screens or shutdowns. So when in windows, it works all day , no error mesgs and faultless , its just getting to desktop So my electronics and M/B knowledge is leaning toward Weak Caps that are load harder on start but less once computer on and thus runs all day- Laptop is 13 years so YES, caps will be worn Bios chip ropey or super IO BUT by now they should have failed totally? Super IO is keeping the mouse on and power on so not a board short plus i checked all that when pulled M/B to check obvious shorts and burnt components Also Power button not always work to force shutdown to try 1-4 restarts to m/B not always responsive - i pull plug Battery and bios battery also removed and replaced When i try to duplicate this fault HOT, i cant do it, only seems to happen after night then start- leading me to think weak cold caps not already ran and warmed ? when i pulled board and tried restarts they worked every time as M/B was warm and voltage filled generally. Is the Power button 3V needed AFTER the board is on, if not then that cant be it as mouse is on every time just wont get going to windows My next step is to monitor the 19V main rail and maybe even scope it for A/C noise when i turn it on cold and see if i can detect weak voltage and ripple from bad caps but not bad enough to have it run all day without fault? hmm Screen problems detected? but screen works perfectly all day and everything else too for months with this problem so i dont want to start reballing chips and make it worse perhaps.. Of course dumb windows says it need repair when it does start after restarts as thats it default position but it NOT windows or the drive.. This is M/B related as all else has been replaced or substituted to rule out.... Inspection- no corrosion or anything obvious. now it hot her in AUST, it might start each morning first time leading me to think warm caps? or simply a chip that is intermittent and hasnt failed yet. Any ideas appreciated as its my mums and valued to her and i like learn what this is or could be...
