I have a Sony Vaio PCG-GRX570 with a second DC jack problem
the first replacement I pulled to hard and it broke, i should have epoxied the first replacement. I felt this would be to permanet and didnot want this. The second
one I soldered and looks good but won’t power up when using dc power, but will with battery power and when tested with meter there is 19.5v power on at both side of motherboard. Is this still a DC jack problem or can I solder wires to the motherboard with an outside jack

I tried to desolder the DC jack on a toshiba laptop. I was using a 15 watt soldering iron & de-soldering braid. I don’t think the 15 watt iron is hot enough. Anyway, a minute copper cylinder came out with the DC jack’s positive pin. It is tall enough to go all the way through the entire thickness of the board. The cylinder (I assume a trace) was damaged (bent) beyond repair. It appears to be a simple cylinder. Can I assume that it is making contact with all 8 layers? Or is it possible that some layers are contacted while other are not. If all layers are, my plan is to stuff permatex electrically conductive rear window defogger tab adhesive into the hole around the positive pin on my replacement jack. The permatex product is copper based and, I hope, will deliver enough current. If the cylinder connected to all eight layers then the permatex product might also. However, if only some layers were contacted by the cylinder (trace) and all layers are contacted with the permatex spackle job, bad things might ensue. Has anyone ever tried this? Thanks for your help.

I have a broken power connector on a Sony Vaio PCG-K37 laptop. I can not find any information anywhere about how to open this laptop’s case. I’ve removed every screw I can find, removed memory hard drive and optical drive, poked at every label or sticker to see if there’s a screw hidden underneath, removed pads on hinges to get at screws there, and still am unable to open this machine. Can someone give me instructions on how to open this so I can replace the power connector or at the very least relocate it to outside the machine?

Thanks.

Hi, maybe ignore the previous email! I’m such a spaz!! I just noticed you have more related topics and my answer may well be amongst those! I’ll finish reading it all and if I’m still in trouble I’ll be back to sook

Hi, I have a Vaio VGN-B88GP. It has just dropped dead not even a light – nothing! A screw driver and a multimeter have determined that yes the battery (circut board) is toast but it should? still boot or do something without a battery?

‘Mr. Fix-it’ has also determined that, um something about pins and voltages. They don’t change. Skim-reading, has left me with the impression that at least some of them should??

I also learned of a ‘CMOS’. ‘Mr. Fixit’ said he didn’t see it or know where it was located (But knew of it:). ??

So what would be the best plan of attack from here?

Hi some additional info that may or may not be of use in diagnosing my problem – if I remove the battery and leave it plugged in – the charge light blinks off and on. If I press and hold the reset button, the charge light turns off for the duration of holding it, and then resumes afterwards.

The suggestion of holding down the power button for 30 seconds was not successful.

Hi,

thanks for this valuable resource.

I have a Compaq Presario 2100US that I resoldered my jack but can’t seem to boot up from AC or from battery (after the jack quit working for power, I could still boot from battery prior to disassembly). The jack is getting power to the the battery charger and the battery status light went from charging (orange) to charged (green).

Pressing the power button does nothing as far as I can tell.

I have some candidates for errors – most of which end up with requiring a new board

1) my soldering job damaged a trace – I’ve some experience with a soldering iron but it is possible I overheated something – is there an easy way to diagnose this? I didn’t see any ‘lifted traces’

2) I have ’spare parts’ – I have screws that apparently didn’t all make it back to their homes – I was thinking that perhaps to power on might require a specific screw for grounding (there was one grounding screw mentioned in the tech docs – the one for the display on the hinge screw which I did mount).

3) dead CMOS? – laptop had no power for 1 week due to waiting for parts after disassembly (this will be my thing to check after I try 6)

4) Electro Static Discharge – no grounding strap and due to a household crisis the entire disassembled laptop had to be moved to another room – also the week of diassembly above while waiting for parts

5) killed the CPU – I used mineral spirits to clean the cpu and heatsink and applied thermal grease. It is theoretically possible some mineral spirit got on the CPU traces or that my thermal grease job was incorrectly done.

6) confused motherboard – a local tech mentioned that at times he has had boards get ‘confused’ after disassembly and that removing all power and holding down the power button for 30 seconds sometimes solves this (will attempt tonight).

Any suggestions for diagnosing whether any of the above are the actual cause?

Hello there I also have a sony Vaio and the power Jack has died. It looks like it heated up and melted it’s all warped and will not work with the ac adapter. How much would it cost me round about to get this fixed?

Krisi Luttinen, You might be able to find a new power jack on eBay. Enter “VGN power jack” for search. If your model is not listed, contact the seller and ask if there is a replacement.

Should I attempt to desolder it? Or I need to add an external jack?

It’s up to you and depends on your soldering skills. I’ve never replaced the power jack on Sony notebooks and cannot give you an advice. Here’s an option. You can leave the broken power jack soldered to the motherboard and relocate a new jack outside the laptop case.
