    Sounds like you didn't plug something in during re-assembly.

The dc in will not fit the power plug anymore


I think the internal socket on the main circuit board has broken . This is common enough with old laptops.

It will have to be dismantled and the socket replaced, which is easy enough for a tech.

Gateway kav60 not charging. i have to wiggle the cord and sometimes it refuses to charge.


I guess you've got a broken laptop power dc jack or power cable.


Symptoms of a broken Laptop DC power jack:


- The laptop only operates when you hold the DC power plug in a certain direction (DC jack is broken or loose).
- The laptop only runs on battery power (no power is getting through the DC jack).
- The laptop gets no power at all.
- The laptop will not charge the battery.
- The laptop switches from AC power to battery power intermittently due to a loose or broken power jack.
- The laptop suddenly shuts off.
- The DC jack may feel loose.
- Sparks come out of the back of the laptop when you insert the power plug into the DC jack.

I have a Sony Vaio laptop, model PCG-384L. It will not power up. My wife indicated that she push some button that lock the power. Can seem to find the button that controls or locks the power button. ...


Typically that flashing light means low battery. Which makes sense, as you probably have an issue with the AC Adapter that you plug into the computer to charge it, or the DC Jack that this adapter plugs into on the laptop. Either of these things will cause your computer to not charge the battery, and if there isn't enough power it won't turn on.

Laptop won't charge


You might need a new battery....you could try removing the battery, plug laptop into ac and restarting. Or you might need a new DC power jack. If you wiggle the cord where it plugs into the laptop, and it starts to charge normally, then the DC power jack needs replacing. http://www.insidemylaptop.com/take-apart-sony-vaio-vgn-s360p-replace-broken-power-jack/

Would any 16volt ac adapter be ok to charge my PCG-VX89 vaio notebook?


you can use any laptop AC adapter DC output-16V and 4A (current). if its jack size natch your laptop DC jack.
if the adapter DC current less than 4A (over 2.5A at least) you should only make the battery charging without laptop turn on!!!
please take a rating let me know how much helped you thanks!

Vaio will not turm on


you will most likely need to replace the dc jack, which is the port where your charger plug plugs into...

To test if your dc jack is bad... Remove the Battery, Plug the Power cord into laptop then attempt to power on... If no lights turn on, no fan spins.. your DC jack is bad...
DC Jacks Cost $6 to $10 but you need to find someone experienced to replace it, or you might end up with a dead motherboard as well..

PCG-K45: No Power: Internal component issue.


Hi,
The Power Charging Board Is Usually Known As A PWS Board.
It should have a model Number Stamped On It. you type this into a blank webpage and do a search. this will give you the model Number i.e PWS 13 OR PWS 15 et,c.
