I have a hand-me-down HP Pavilion N3250 Laptop running Windows ME. It was performing fine until I started having problems with the DC jack where the AC power adapter attaches stopped functionally properly. After researching th problem, I found that it was apparently a common one in which overheating causes one of the solders to the jack, usually the positive side, breaks or unwelds from the heat causing intermittent power. Being fairly savvy with desktops and not having the money for a professional repair, I undertook the project, using a photo website to help find all the screws and the proper order of removal. To make a long story short, I disassembled, resoldered successfully, and meticulously reassembled everything (no leftover screws!). The power connection nows works great, but I have no video display! The lights all come on in proper boot-up sequence, but the screen shows nothing. Can anyone tell me what to look for as far as what connections might be at fault when trying to troubleshoot? The large card that contains the external VGA connection, serial port, and printer port appears to be properly seated. By the way, the external VGA connection does not work either. Attaching to a separate monitor produces no display as well. So, could this video/sound/serial/printer port card be at fault? Any and all input accepted gratefully. Please don't flame me too bad, as my usual patients are dogs and cats. Thanks. Bill Snyder, DVM firstname.lastname@example.org

Re: HP Pavilion N3250: No video after DC jack repair
Its sounds like some damage was done during the dismantle/reassembly and now the onboard graphics has dies like you said. Could have been cause by static perhaps. Easy to damage them as i have found out myself so dont feel too bad.

If this is laptop, In laptops the graphics cards are integrated meaning they are a part of
the motherboard. There is no slot or place to put a card in, usually it
is in a chip that is fused to the motherboard and the only way to get a
new one is to replace the motherboard itself. Either try to play around
with settings to get the most out of it or buy a new laptop. I would
say upgrade your graphics drivers (nvidia website) and Direct X
(microsoft website). Turn off all background tasks and services in your
task bar when running games. And you can tweak the game settings within
the games also, turn off shaders and keep screen resolution lower
I have a smilar problem, with the ATI enabled the laptop black screens on startup.
If you disable the ATI x600 in Device Manager (using safe mode) the laptop works fine as the ATI is not being used.
Solution is to replace the ATI x600, which unfortunately is a specialist job as this is soldered directly onto the motherboard. Or replace the motherboard.
I have located a company in Manchester (called CRM) that repairs HP computers, and they can repair/replace the ATI for around £175, or replace the motherboard for about £250. Replacing the board gives you a 12months warranty. add VAT to those figures. There phone number is 01618881232, I have found them to be very helpful.

I had the same problem for a year or so. I used vista in the meanwhile, but after a 3D bug I got upset and decided to try fix this bug, finally succeded in it. I'm sure it has something to do with the memory, but still there's a mistery........
The solution : It can be a little wierd, the softwares i used are : ASO - Advanced System Optimizer 2.2 and Mobility Modder 1.0 Final.
Step 1 (ASO) : In the windows optimizer at the System Performance #2 I turned on the : Improve Core Kernael Performance Enable Large System Cache (I made the cache size 1,024 - not sure if this was necessary) Theese options were to force the system to write the swap on memory instead of your HDD
Step 2 (Mobility modder) : First download a new Catalist Driver from anywhere on the net, then the modder from :
