Question about HP ProCurve Switch 2650
When I plug the adapter in the yellow charging light is blinking. Press the power button and the blue power on light just blinks at me like it is in standby or hibernating and wont wake up.
I can hear faint electrical humm from the motherboard. I tested the Adapter it tested fine and I tested the fuse on the motherboard also tested fine.
I have removed the cmos battery/all the drives battery etc. still it appears to be in sleep mode.
I have taken it apart and reassembled it 4 times and cannot see any burnt spots on the mobo.

Do you have Vista? If so, you should contact HP directly. I had the same problem which occured 3 months after my warranty ran out. I called HP and was told(after they tried to sell me another laptop) that I installed the wrong antivirus program but since I never used my warranty, they would do me a BIG favor and fix it for free. I then waited 14 days for my new laptop and was very happy when it was returned only to find out 3 months later that there is a RECALL for HP laptops with the Vista program that was a MANUFACTURERS defect. THEY HAVE TO FIX IT AND FOR FREE!!!!! I hope this helps you. Good luck.

Try hitting the "Windows" key on your keyboard to bring it out of sleep mode. The "Windows" key is generally found on the bottom row of the keyboard, near the Alt and Ctrl keys, and it has no letters on it, just the Windows logo. That key brings my Windows Vista machines out of sleep mode when other keys won't.
As for the power button, anytime you need to force a computer to turn off, you can press and hold the power button to do so. Usually, you need to hold the power button for 5-10 seconds and it will shut down. Use this option with caution, as it turns the computer off without running through the shutdown process and can cause you to lose data.
Hope this helps.

all you really need to do to find out if it might be broken is to check and see if that DC Jack on the computer is "wiggling" around, if the center part is moving around. If it is, then there is a chance that it is broken. I used to work at a computer store where the owner would resolder new DC power Jacks into laptops, but he was the only one in town who did that. So you might want to check around at the local computer repair or electronics stores to see if someone does that type of thing. Also, have the power supply checked out, it could just be dead.

At the risk of subjecting myself to your possible wrath, I suggest you replace the motherboard. I don't know your computer repair prowess, and am not doubting it for a minute, but I 'stand' here to tell you, that it's just not that simple.
The hardware components are installed down into a bare motherboard. The leads for the hardware components are in their 'raw' state, where they hang down past the motherboard. Then the motherboard is heated up using a hot air soldering method, and the solder flows over the leads making a precise, pretty little solder joint. This is done with robotics. Once this is accomplished, the extra length of lead is snipped off.
Some components are installed by hand. Very few of them. The operator uses a soldering station, and an instrument that magnifies the area by a great amount. Looks like a binocular microscope. One, two ,three, and the next motherboard comes up, and the same part, by the same operator is installed once more.
Again, not doubting your expertise in this area, but if you have use much heat, or linger too long, you stand the chance of making the copper circuit trace, lift right off of the motherboard, when you go to remove a component. Not enough heat, and you can't remove enough solder, nor get the lead to come out of the hole. (I use solder wick. Also known as Desoldering Braid. Solder ****** tools are for the bird's! (Desoldering Tool)
Same thing with soldering a new component in place. Too much heat or linger too long,....well you know what happens. Not enough heat, or staying in position long enough, plus using the right technique, you get a cold solder joint. It's a lot of fun, when you reassemble the laptop all the way, and find this! Guess what happens next? Yep! Do it all over again!
I'm not a saleman for Ebay, but I find a lot of my motherboards for laptops on there. I would also suggest looking at -> Laptops for Parts.
