Computer screen flickers, tries to go into sleep mode constantly

My computer keeps wanting to go into sleep mode. I looked on the Event Log and apparently it's being triggered by the button or lid (neither of which are being touched at the time). I changed the settings so that the computer won't shut off when the lid "shuts," and sure enough the computer no longer goes into sleep mode, but it will flicker like it wants to. Sometimes it will flicker continuously on and off until I can get the computer to shut off. During these times, the back light will sometimes fail to come back on, but I can still see whatever's on my screen. It also sometimes will flicker and then just go blank, during which the computer is still "on" but when I push the power button to shut it off, the computer is unresponsive.

I have noticed that my wireless switch (just below the touch pad at the very front of the computer) or the area around it is some how connected to this problem, because when the screen starts freaking out, if I push down in that area, the screen will come back on for anywhere from a minute to hours later.

I literally am at the end of my rope with this problem. I'm wrestling with whether to keep the computer and fix it or to buy a new one since this one is almost 4 years old. I would appreciate it if someone could point me in the right direction as to what the problem is so I can figure out whether it's worth it to fix it or not. Thanks!

  1. It sounds like a loose connection, or possibly a crack in the circuit board copper traces.

    I don't think this would be easily fixed.
  2. I gather the 'computer' is actually a laptop. What make and model?

    Yeah, sorry, it's actually a laptop. It's a Sony Vaio VPCEB290X.
  4. Did you try their support - http://esupport.sony.com/US/p/model-home.pl?mdl=VPCEB290X&LOC=3&session_id=58d07d83a503f4a42066f8e3e29fa842#/howtoTab ?

    Does the flickering change if you move the screen up and down at the same time?

    I recently had the computer taken in to repair the wireless switch/replace the wireless card since the wireless kept turning on and off randomly, and the tech said that the inside of the computer looked fine outside of scorch marks on the connectors attached to the wireless card. Is it possible that he just overlooked it if it either of those things are the problem? My computer was having this problem before he even looked at it, just for clarification.

    I have looked over their support page before under the Power & Battery and Picture/Screen/Display categories (and skimmed over the others), but couldn't find anything that really addressed the specific problem I'm having.

    There's no effect on the flickering if I move the screen. When the problem first started occurring, I moved it around to see if it would fix it somehow, but I didn't notice any change with it.
  7. Well the next suggestion is a faulty graphics card - https://docs.sony.com/release/specs/VPCEB290X_CTO_mksp.pdf an HD5470

    You should take it in for a check, service and if necessary, a repair.

    The big problem with taking it in for repair is that I no longer live in the US (where I bought the computer), and don't know the language here well enough to be able to discuss it with techs. I've also been told that if I go to an electronics store here, they might even refuse to service my computer because the OS is in English/not bought here. I was briefly back in the US a few weeks ago and had my wireless switch fixed to see if it would help the problem but of course this particular issue didn't get resolved and I ran out of time to try anything else.

    However, I'm guessing by your suggestion that you do think it's worth fixing? I could try and find someone to come with me and talk to a repair place for me, but my main fear is dumping loads of money into this when it might save me money (and sanity, at this point) in the long run to get another laptop.

    Its not a bad laptop. For day to day use anyway.

    A good new one would be something like this - http://www.newegg.com/Product/Product.aspx?Item=N82E16834152589
    but then here at Tom's we're probably more gaming oriented than average laptop users.

    Yeah, I love this laptop, and the fact that it has survived this long means something to me considering my track record with computers haha. Since this is really the only problem it's having, I'll try and figure out if I can get it looked at and go from there.

    I'm not completely opposed to getting another one though, as I've been looking at newer computers and trying to save up some money. I was actually looking to buy a gaming computer this time around, and was on this site before to check out what specs I'd need in a laptop to be able to play something like Titanfall. I just wasn't sure when was a good time to buy, and since anything electronic (or rather, EVERYTHING) here in Japan is SUPER expensive, I might be better off buying a computer online and shipping it if fixing the computer doesn't work out.

    Anyway, I really appreciate all of your help! Cheers! :)
  11. You'll find you can't ship it out of the US directly. It'll have to go to a US address then you.

    It's the same for other things like snowboards/boots/etc., so I figured. Here's to hoping I have a kind family member who will go through the hassle of picking it up and reshipping it for me if I end up going that route!
  13. OK Sorry we're not much help. It's much easier sorting this sort of stuff out in the US.
