IBM Thinkpad R40 DC Jack


No matter how many times I stress that when the jacks start to fail, you should take it to the shop. With each delay and use the problem only gets worse and more expensive. Wiggling the DC Jack to make the positive side supply power to the board eats copper! Every time there is less surface pad left, and eventually you will totally eat all the surrounding copper making a 25 min job into a 1 hr job (or worse - unrepairable).

This jack nearly killed the motherboard which would require a replacement (expensive).

I cannot repair laptops for you via the internet, I can only answer questions related to posts. This is because I have not had experience on every motherboard that is out there. Bear with me.

If you do need it repaired. Contact me for quote (US/CDN Only)

Important parts on DV6000 and DV9000 series

Image
These are important parts if you are looking for shorts or opens on the DV series. This image shows the location of the FDS6679. A common cause of shorts in the DV series. When the power supply is plugged into the laptop and it shorts out/turns off it's usually caused by this MOSFET being shorted.  Plainly stated. You plug the adapter into the DC Jack and the Blue Ring fails to light up, and the Power Supply shuts off. Giving no power to the tip. To reset adapter, unplug from AC (mains) and wait 15-30 sec. Then plug in again. The adapter is not damaged, since this is how it is protected. These parts do not determine charge time or per centage. The FDS6679 only closes to complete Positive circuit.  The AO4407 only closes when the battery is plugged in. As a test- Check the voltage of the Drain side (pins 5-8) with AC adapter and no battery - you should see 0 volts.  When you contect the battery you should have 10-14v depending on DV6000 or DV9000 series. IF the AO4407 is open

Dell Inspiron 1501 - Dead, No Power, Won't Charge

Image
Picture 1 This is a common problem with the Dell Inspiron 1501/E1705/6000 series. Most of the motherboards use the same general layout and design. You can tell by the white and silver cases used. From my guess, the solder on the leads of FL1 [filter] tend to lose contact after regular use. Perhaps eating away at the Filters pad, due to the current it is carrying. Sometimes it may be years before it finally lose contact, other times only months pass. In this instance the laptop was a couple of years old before it failed. How to fix it: Picture 2 Remove FL1 Clean contact area Replace FL1 Solder back onto clean surfaces. Click picture to see larger image Picture 2 Shows another failed NO Charge issue. FL1 cannot handel the surge when plugged in and eventually arcs then lose contact with the solder pad.  In this case if you cannot find a replacement, you can simply turn the coil [FL1] upside-down, and make sure you have positive voltage on  the circuit.  Try to t

Tips on Testing MOSFETs

Image
Imagine the flow direction Source to Drain This is how I test FETS  What I will try to do here is to provide a little insight on how to test  MOSFET's in circuit the easiest way I can think of. Essentially the FET acts as a switch, and the GATE either opens or closes the switch. When power is supplied to Pin 4 (usually the GATE) it will either open or close depending on the type of MOSFET it is. The arrows shows the direction for reference when using a meter to test.   Setting the meter in DIODE mode. On the N-Channel FET place the NEG lead on Pin 6/7 and the POS lead on Pin 2/3. You should get a reading of some value ~100 to 500 or higher. Imagine the flow direction Drain to Source On the P-Channel FET place the POS lead on Pin 6/7 and the NEG lead on Pin 2/3. Again you should get a reading of some value ~100 to 500 or higher. The reason I say pins 2/3 and 6/7 is because they are common,
