Dell D610 Charging Circuit / Power On Issue
Hello all,
A few months ago I snagged a D610 at a yardsale for five bucks. Its a pretty nice system and is surprisingly came with the following configuration:
Intel Pentium M 2Ghz
2Gb PC2-5300
ATI X300 64mb
Hitatchi Travelstar 100gb 7200rpm
14.1" SXGA+ Display
The only issues it had were blown speakers, bad screen inverter, and a failed attempt at a reinstall. The whole thing worked perfectly, battery included.
Spring break came and it sat in my bag unused. I pulled it out to check something and it didn't power on. I assumed it just sat in sleep too long and plugged it into a 65W Dell charger. I didn't try to power it on though.
A couple weeks later, I bought a 90W Dell charger for a customer, and decided to test it with the D610. I noticed that the laptop still wouldn't power on, and that the power indicator on the battery actually showed it as having a 60% charge.
Some tinkering went by and I can get it to power on and charge the battery, but any movement to the system and it will immediately shut off. In this "power off" state, the system acts as if it can't get power from anything, and it will also not charge the battery or power up from the battery.
In the working state, it works fine. Battery, 65W charger, 90W charger, you name it. The battery will charge in this "working" state. But if you move it too much, it reverts to the "power off" state.
I'm scratching my head at this, any insight?

If moving the system causing it not to power up there it is going to be some type of hardware problem, hopefully not a defective system board, but possibly a loose device shorting the system out.
In troubleshooting I would perform typical no post troubleshooting. Try to isolate the system board as much as possible, remove all external devices, the battery, memory, hard drive, optical drive, any cards, even the keyboard. Plug one memory module in and attach the AC adapter and power up. If the system is stable try adding any additional memory modules. As long as the system is stable keep adding one device after the other and see if the problem returns. Since this could simply be a loose device keep an eye open and make sure that all components have a solid connection.
Please let me know how it turns out.

I tore it down this afternoon and cleaned it.
Had the motherboard sitting on a piece of paper with the cpu, 1 ram stick, power button board, and heatsinks attached.
It seemed to work whenever it desired, even with different ram sticks. Moving it would cause the board to shut off and would only power on randomly.
Assuming its a bad motherboard?

Unfortunately, it does. I was hoping that it would be otherwise.

Since you don't have much invested, you could try the oven solder re-flowing technique. Do a web search. It doesn't take much time, and works for many.
