Can anyone identify this power supply pinout, it’s a 7 pin connector on a custom single board computer?
The 7 pin header is simply labeled “power”. Testing with a multimeter reveals that pin 5 is ground (going left to right). There is 735 ohm to pin 1, 732 ohm at pin 3, 708 ohms at pin 4 (respective to ground). All other pins read open. The board contains an advantech “system on module” with 64mb of ram.
There is no power supply, that’s the problem. I suspect its a simple 12v/5v supply but I have no idea which pins need power, and I don’t want to burn anything out in the process.
Is there a name or model number on the power supply module?
Is it possible for you to power it up to take voltage readings?
A picture of the unit may also be helpful for clues.
Can I use my TV as a monitor for my laptop using a vga 15 pin to 9 pin dsub port?
Have tried s-video and the picture is fuzzy. Will plugging into the rs232c dsub din port work or is it just for sending commands to your tv?
The ports on my TV are HDMI/S-VIDEO/STANDARD AV
Can I use the HDMI port
You are correct, the RS232 is only for sending commands and cannot be used for video input. S-Video is a comparatively low quality video connection that only supports low resolutions, hence the fuzzy image.
If your TV doesn’t have a VGA or DVI input, then theres no real way of getting a high quality image from a laptops VGA connector. If the laptop has DVI however and the TV has VGA/DVI/HDMI then this is another story.
Additional:
I’m afraid you can only use the HDMI if your laptop has a DVI output. Otherwise, you’d have to buy a converter box.

I need a laptop for school & personal use. I take most of my courses online using Blackboard and need Microsoft 2007 programs including Word, Excel, and PowerPoint. I will also download music, browse the internet, watch movies, and download pictures from my Kodak Easy Share using it’s accompanying software. I do have a PC at home, but will be using this computer as my main computer for 2 weeks while I am in Miami getting married and going on my honeymoon. I don’t want to spend more than $700 total. I am very torn between buying a Vista based computer versus a Windows XP based computer. I would rather get XP, but it seems the best deals are on Vista. It would be helpful if people could leave me links so I can check prospective laptops out. Thanks a bunch!
If you want to use Vista, look at the requirements…and double it at least and make sure it’s certified. Triple if you can afford…then Vista should rock your socks. If you learn how to use it, Vista features and technology blows XP away…when it works.
But if you have old programs, they might not work (esp. with 64-bit version). Google “vista compatibility list”. You have to know a bit about computers to get them to work (if they have problems and if there is a solution. Internet has a lot of solutions that smart people share).
Ultimate is the best but if you don’t think you need anything that fancy, Home Premium is good too. SP1 made things better and more compatible with hardware. Unfortunately, Microsoft marketing made people think it will work with old computers but it’s very risky so that’s why there are so many problems. It’s too far ahead in technology and requires new hardware and too many manufacturers sell cheap computers that don’t run Vista good. Get a good video card if you want to Aero graphics (at least 256MB 128-bit in the newer cards). Better if you can afford.
