suky 0 Posted September 21, 2009 In my opinoin, when getting the blue screen, the ccd must be worn out. How long does it work for you? It is very possible that you need to change a new one. May be some superiors can give you better ideas! Share this post Link to post Share on other sites

scorpion 0 Posted September 21, 2009 You will need to replace the external power supply, and the small internal power supply board. These are expensive! You might find a laptop power supply that has the connector that has the 19 volts dc, and the wattage. The inside board is hard to find, and they are expensive. How much are you willing to spend on the parts?
