    The cost difference between a new screen and a refurbished laptop from Dell isn't much. https://www.dellrefurbished.com/lapt...lter_brand=189 and the integrated graphics series 4000 will strangely enough run TANE Middleton for laptops runs at more than 20 frames per second, 27 in parts on an i5 so its just a matter of being very careful with the content. The cosmetic grade A ones are the nicest and the 1600 by 900 screens aren't bad.

    It depends on the Dell laptop. It was pretty easy on my old 2510, took about 1 hour. I found a well priced screen on eBay (close to $50). I would recommend trying that before buying a whole new PC.

    Most definitely ns2616. Replacing the screen on the Dell Inspiron 1545 is also easy. That is my last option before buying a new computer. I had the screen detached and connected it to the television by a VGA cable and everything displayed properly. Hopefully, the new inverter board that I ordered will solve the problem. My screen is a CCFL.

    The new inverter board that I ordered did not solve the problem. I connected the new video cable and new inverter board to my laptop and powered it on, but the display is still very dark. I can still see the desktop but I need a flashlight to see the screen. I am starting to think that the light in my screen is probably dead. Before purchasing a new screen, I found another method on youtube. Under the 40 pin connection for the video cable, there is a tiny circuit called F1. I read that if it is not bridged, that could be the reason that the video or backlight on the screen may not show. I was going to try and solder the circuit because it is exposed on my motherboard. Right now, the F1 circuit displays the letter P. I think if I solder the top of that circuit, it should hopefully work.

    Bad news. I just soldered the f1 circuit on the motherboard of my Inspiron 1545 laptop. There is another circuit to the right of my f1 circuit but the circuits are extremely close together. I applied solder but it was very difficult. Since the circuits are very small, both of the circuits are nearly soldered together now and I am not sure how to remove it. Now, when I connected everything, and plugged my AC adapter to the wall, the power brick would power on but as soon as I connected the adapter to the laptop, the light on my adapter would immediately shut off. Could I have caused a short circuit by those tiny circuits on my motherboard being soldered together. Would it be recommended to purchase a replacemement motherboard for my laptop. To be honest, after seeing that my laptop now won't power on, I am nervous to continue working on the motherboard or components connected to the board, because I don't want to cause serious damage to the computer. In the event that my laptop completely no longer works, is it still possible to get the data from my hard drive? Please help, I hope I can get my Inspiron 1545 up and running again. Hopefully a simple motherboard replacement will solve the issue.

    Unfortunately motherboards and many others boards are generally not designed to be repaired. Frequently they are multi-layered and initially soldered using flow-soldering techniques which do not lend themselves to hand soldering and even when they do, the solder used to often have different properties and melting points. To remove solder it needs to be sucked away using a solder-sucker, ideally an electric one but even a handheld is better than nothing.

    Data can be recovered from most hard drives assuming they are serviceable, un-encrypted and formatted to a common format. Both 1.8" and 2.5" laptop hard-drives can often be installed into a USB adapter case and plugged into another computer but ensure that the relevant interfaces are compatible i.e. SATA/PATA. Peter

    Thank you for letting me know, I didn't know regular solder wasn't really designed for the laptop motherboard. I might be better off buying a replacement motherboard for the laptop as well as a new screen. If that doesn't work, my last option would be to buy a new or refurbished laptop for my projects and assignments. I was a bit nervous with working on the motherboard yesterday because the circuit that I soldered is connected to a video connection or fuse that is rated at 32V. I am also going to look at getting the adapter to connect my SSD to so I can get the data off of that drive.
