Sudden black screen

[Adit Gadkary]

Hi . I have a old Sony Vaio laptop which suddenly swiched off and now when i start it the bios startup sound comes but no screen no black light . All this started here 

1 : i lost internet and unable to connect to wifi 

2 : i started using usb tering 

3 : all of the sudden my laptop forced shutted down and when i press power button the bios sounds comes but no screen no backlight. All other things like usb hub , power light  lights up only screen . Last time the same issue around a month ago i opened it and did nothing special and it fixed by itself magic but i don't want to open again. Nither bios menu shows up . I am now editing this topic as it's been around 10 mins and i tired starting my laptop and without any issue the screen started  to work.  But whats causing the problem and a permanent solution i wnat

Sounds about right for an old Vaio. Anyway, if it happens again, do you any external monitor or TV that you can connect it to to see if the lamptop is actually running and giving any output. If it does, you may be able to narrow that particular issue down to a failing display connector or the display itself. As to the WiFi issue, again could be a loose connection on the WiFi module which is usually a little rectangular stick that's plugged into the motherboard. Or it could all just be a failing motherboard, which is highly likely.

I'm pretty sure it's either your motherboard or CPU failing in that case, either way the CPU is soldered to the motherboard so fixing the issue would mean replacing most of the laptop which for an old laptop may not make sense financially, unless there's still supply of replacement parts on eBay for cheap.

Cpu can be replaced but if other things like external HDD pendrive , mouse headphones etc etc work but not keyboard makes me think again

There is a good news just now i started my laptop and the keyboard was working in bios then i booted windows logged in using on screen keyboard and plugged in my keyboard after some time i saw a pormt saying installing UBS keyboard and boom my keyboard is working but now after some time same issue keyboard not responding . I think i should try it on Linux live session

I think u are correct because i am not able to use the keyboard in bios also and sorry to mention it late that my internal keyboard is stopped working longtime ago due to removing it and broken cable . The keyboard the issue is having is the external keyboard

if it's just the cable from GPU to display that are getting pulled every time you close and open your lid, and will break sooner or later. it's usually around max 50$. but you have to know how to open and fix it. .. i'm sure there are youtube video's on how to do it. 

 

keyboard... did you replace batteries? ..  or is it cabled? 

 

sounds like you should get a new used one cheaper than fixing it.
