This email I received from one guy last evening. He had a problem with DC jack on his Toshiba Satellite 1900 laptop and fixed the problem by resoldering the DC jack on the system board. The problem is very similar to Toshiba Satellite M30X, M35X, A70 and A75 power jack issue.
I finally got around to using the guide you provided to try to solve the problem on my Satellite 1900.
The power plug kept not making contact somehow and ultimately it would shut down.
You would see in the Toshiba Power Management Utility in the Battery Power Meter, the charge bar would show “Online Discharging”, which doesn’t logically make any sense anyway.
If you wiggled the plug at the back of the laptop it might make a connection but could fail at any time with no warning if you weren’t paying close attention to the red/green charge light on the front edge of the laptop and discharge the battery.
I took it apart and discovered that the barrel power socket on the back of the unit that is soldered in to the motherboard had over the course of time worked the centre post contact loose and pulled away from the solder.
There is no real anchor for the socket to the motherboard or anywhere else on the case plastic. The solder on the motherboard that holds the socket in place is very weak, there is not much there at all.
Over the course of normal use, and being a laptop people trip over the power cord from time to time adding to the stress of the almost non-existent solder.
All I did was to re-solder the damaged connection, and I beefed up all of the other three solder points on the motherboard as well to try to strengthen the contacts against failure in the future.
I have provided a picture that if you look very closely at the base of the pin as it goes through the circuit board there is a slight gap between the pin and the solder it used to be attached to.
I search all over the internet and the only resolution I could find for this problem was to have the motherboard replaced. It appears that is not the case. I repaired it 6 hours ago and it hasn’t failed since.

I have a M35X-S149 Toshiba Laptop I replaced the DC Jack. Works fine but no charging. I know that RC1 has come off the board. What is RC1 for? and also what could I do to fix the charging issue.
Thanks

Haai. I have a big problem with my Satelite 1900-703.
When i’m charging the battery, the leds on the front works normal. When i’m starting the laptop, after 10 seconds he shut down and all the leds are blinking (on/off).
I checked the powercharger and he gives the normal volts. I checked it with a other battery (new) and i have the same problems.
Conclusion: He don,t charged the battery’s and i can not work with the ac/dc apdator.
I have contact Toshiba (Netherlands) and thay say that it is a hardware problem (maybe motherboard) and they cant help me.
I NEED ONLY 30 MINUTES POWER !!! To save my photo,s and documents for backup !!!
Do you know a answer for me !!!
Thanks for reply

Hey RollCam,
May be you can share you knowledge with us? I would love to know the real solution for this problem. I’ve tried to find this solution on your blog without any luck. Can you share?

Pewit,
What socket you are trying to replace? Is it power jack?
To remove old solder I usually use a solder sucker. Search Google images for “solder sucker” and you’ll see how it looks like. First you heat up the old solder and after that you remove it with the solder sucker.

Hi Welly,
Sorry for a late response. I missed your comment. What Toshiba model you have? I think that upgrading BIOS can help.

Its not just the power jack that is loose, there is more to it, and not as easy to fix as you think. I managed to fix one m35x but the next one didn’t work because its almost imposible to fix, you have one shot if you dont get it then its f-up… Toshiba and I know the real solution. So again, its not just the jack…. If you replace the jack and the problem still occures, let me know.

I have a motherboard with a damaged socket and I have the replacement - but I can’t remove the old socket.
I have used a solvering iron on the solder of the anchor points of the heatsink/socket surround but it won’t cxome free - is it better to cut this off and then remove the pins that go through the board separately?

Hey Ashley,
What brand is that? Is it still under the manufacturer warranty or under Best Buy warranty? I think it’s not right that they quoted to you $385. We’ve seen a lot of Toshiba laptops with damage like yours and always repair it under warranty. If the laptop still is under the manufacturer warranty, try to ship it to a different authorized repair center.

I know nothing about computers other than how to turn it on shop and send emails. My computer wasn’t charging when plugged in and in order to get it to charge I had to wiggle the jack until I could get the light on the front to come on and then wrap the cord around the screen. Finally, the power jack fell into the computer. I took the laptop to Best Buy where I bought it and unbeknowst to me, I still had a warranty. I had it shipped off and got a call today saying that it was considered physical damage and that it would cost me $385.00 to get it fixed. How ridiculous!
