Is it possible to upgrade the Core 2 Duo T7300 to a P8700 from a Dell Latitude E6400? I saw from guides that Penryn CPUs are compatible with the T61 and have a spare E6400 with the P8700 in it, and figured that could work with mine.

Thanks in advance

It came with a 2878 dock and a battery. I am unable to find a charger that fits the 2878 dock but is able to find one that fits the laptop itself. The battery is able to be charged by the device (the battery LED was amber then it turned green), and when unplugged you can hear the coil whine of the battery/motherboard circuit. However, no matter what I do the machine will not turn on (the power LED will not come on)

And thus I took apart, cleaned and reassembled every part. The symptoms remain, so I probably didnt made it worse.

Note that my unit come with a fingerprint sensor, and that the hard-drive is missing. However, I do not think either of these will prevent the machine from powering up and post. I put a Win NT workstation disk in, just in case.

It come with two stick of Hynix DDR2 memory, but then, again, this should not prevent it from powering up.

The machine come with a full set of Centrino (north, south, CPU, wireless), and I think it is the 900 Series Sonoma Pentium M Dothan “variant”. It also come with AMD ATi FireGL Mobile.

After these years I still want to find a way to fix it or finding a working/improved version of motherboard.

Is there any chance?

Deeper explanation…

Set the computer on a table, turn it on, and it works perfectly. However, if you pick it up off the table and slightly twist the base, the screen goes dark and a few other things happen (explained in a moment). It’s a specific twisting action; with the computer open, the hard drive is under the right palm rest and the PCMCIA cage is under the left palm rest. If you apply pressure on top of the right palm rest and below the left palm rest, the base will slightly twist so that the right side (the hard drive side) is lower. In that position the screen goes black (as if the video cable were unplugged) and the hard drive stops accessing; the computer is effectively “crashed” at this point. It doesn’t respond to a network ping or anything. Twist it back so that the left side (the PCMCIA side) is lower and the screen and hard drive both “wake up” and things continue like nothing ever happened. As long as the computer is kept flat/level/twist-free, it will work perfectly.

Once in awhile, like when I’m experimenting by twisting it multiple times, the screen will get some odd artifacts on it. Even more rarely, the computer will actually crash (complete lack of all activity).

In testing…

• Definitely not software-related as I’ve clean-installed the OS, so nothing bad is there.
• Disconnecting the on-board video cable and driving only an external screen does not solve the problem.
• Removing the keyboard and track pad assemblies does not solve the problem.
• Unplugging, cleaning, and reseating every internal cable/harness/etc does not solve the problem.
• Removing the battery and running only on AC power does not solve the problem.
• I was thinking perhaps there was a short happening below the ATA bus (not SATA) at the lower enclosure, so I insulated it with a bit of electrical tape. No help there.

Clearly there’s some kind of intermittent contact issue happening. Twisting in one direction disconnects “something” and twisting in the other reconnects it. I just have no idea where I might look to find where that “something” might be. Ideas?

I made a big mistake opening the laptop. First of all I wanted to clean out the fan and repaste the system. Later I was able to remove the fan, but the rest of the cooler was just too hard for me to get off. Then I put the cooler back in and everything is okay… until i test the laptop. I put the keyboard back and plugged in the cables and the screen didn’t work. So I tried to remove the keyboard, but it cracked when I opened it. And then when i tried removing the cables, one of them broke. So I’m in a really bad situation, because any help is really missing for this laptop
