Acer 5536 black screen when switching on and fails to boot up

My laptop fails to boot up correctly, you can hear the fan kick in but it does not load up. 

 

I power down and re power up several times until the machine eventually comes on. 

 

It appears to be when the machine has been left on for a wee whileand warm it appears to boot up.  This can be after about 30 mins with the power connected to the laptop and switched on although only the fan running and black screen. 

 

When the machine does come on it functions perfectly, I have also tried multiple checks with ram,hard drive etc and all ok?   

 

At a loss, any ideas?

    I have an Acer aspire 5517 and my problem is similarish to that one, but I know that theres something wrong with the back lighting. When you put a flashlight on your screen can you see anything or is it just black? Another place to ask these questions would be on Tomshardware.... A lot more helpful then this place.

    First, check that your video adapter is OK by HDMI cable out to a TV during these black screen epiosodes. You may have to toggle the Fn+F5 or Fn+F6 to get the TV to display.

     

    If your TV displays, while your LCD screen does not, then the ribbon cable to the LCD lid display either needs to have its connectors re-seated or it has an intermittent conductor break usually near the lid hinges if you have a habit of opening and closing the lid too much.

     

    If it's the ribbon cable, check Amazon for a replacement.

    Again, have you tried to HDMI out to a TV to check if your graphics adapter is functioning? You may have to toggle the TV on with the Fn+F6 key combo. If the TV works OK, then you either need to re-seat the connectors on the video ribbon cable or you need a new cable from Amazon.

    That's not a good sign as I think the graphics card is integrated with (soldered to)  the MB. First thing I'd do is pull the battery, keyboard, screen bezel and back cover and re-seat all the accessible ribbon connectors. Then before re-assembling everything, try to gingerly re-insert the battery and carefully power up to see if those steps made a difference.

    My only solution is to bring it to the tech then?

    Yes if you're not comfortable with pulling it apart to try to re-seat the connections. However, this might not resolve the  issue since a graphics card failure is an equally-likely possibility in my opinion. In the latter case, it might be most practical to transfer your data files from the old hard drive as part of a deal on a purchase of a new machine.

    There are some tutorials on the net for taking apart acer laptops.I will take a look at that since I have nothing to loose.

    Good for you! The biggest problems are the plastic catches holding the panels together along with all the screws. Don't worry too much if you bust a few. That's what electricians and duct tapes are for. A keyboard is affixed to one of my notebooks with black electrician tape --- hardly noticeable. 8^)

    Its alive!

     

    Thanks to the towel trick I saw on the net. Don't have to be a computer tech for reflowing the nvidia graphic chip.Just power on the laptop then block the ventilation bays for 10 minutes.This will create enough heat to solder the chip back on the board.Uncover the machine then power off then on.Voila! Probably a temporary fix but now I can make backups of my important files.

     

    Thanks!

    Hmmmm. That's a new one for me. I dunno. Plastic panels would start to melt if it got hot enough inside to melt solder. More than likely, the extra heat probably expanded the traces enough to temporarily bridge but not solder a small gap. Maybe it'll last longer than we think. Good show!

    Same nvidia chips  they put in other computers like HP and they are plagued with these problems.I will never buy another computer with a Video chips soldered on the motherboard.Most desktop have a distinct video cards and this is why they are less prone to heat problems...bigger fans also help cooling the machine a lot.My advice to most laptop users is to get the inside of the case cleaned and fan dusted,heat sink fins cleaned and thermal paste replaced.

     

    Thanks again for your help!
