A year ago or so (I have a thread of the problem also) my laptop stopped to show what's happening during the boot so the display was blank on laptop, until windows booting starts then the picture. If I would connect it to an external monitor with the HDMI, then I would see the boot too. I left it like that because it didn't bother me that much.
Anyway, coming to the real problem now. Few days ago the laptop failed to wake up from sleep mode and I had to shut it down with the power button and then turn it on, it would start. However, 2 days ago I shut it down instead putting it into sleep mode as I usually do and didn't manage to turn it on again. The laptop powers up, the leds light, fan starts to spin but it wouldn't show anything nor boot/ post as it usually does. I connected it to an external monitor with HDMI but nothing there either. It just stays powered on but never boots or shows anything on the screen.
I tried the usual stuff, taking out the RAM modules and trying with just one and different slots, nothing. I took the SSD and HDD out, still nothing. I also tried my other CPU which was working fine when I took it out for a little better one, nothing. I disconnected the motherboard from everything, only CUP, RAM, fan and wifi card left in it and tried it like that but also nothing.
I found the schematics but have no idea what should I check 😅
I'm quite a newbie with this but for some reason I'm suspecting the BIOS chip? I found the bios update for my laptop and I have a BIOS flash tool so I'm thinking to try and reflash the BIOS, but have to locate it first.
Any thoughts, suggestions?
If needed I will take pictures or whatever, when I have some extra time.
Thanks!
