Worked like a charm on my wife’s L355.. took about 3.5 hours this afternoon… much of that was dremel’ing down the plastic parts. THANK YOU!!

Hi, I was looking to fix this on my laptop. I went ahead and followed instructions on removing everything and i got everything out according to plan. only problem i have is the dvd drive. on the site you referred the L305 model doesn’t have a little slot to push the drive out. and really don’t have anything (at least where i looked on where to remove it.) I did however put a lil something inside the laptop kind of like wedges to keep the power jack in place (while not interferring with anything else that’s electrical) because my power jack housing was broke, but its nice and firm and so far so good. if you can post a link or somewhere where you can remove the dvd drive in order to fully get to the power jack cord that’s underneath it I would really appreciate it. Thanks in advance.

Deanna,

could it somehow be wrong for the p305d or is this okay to have that little space of the post showing? or is it just enough to not make a circuit and power up? so there’s no usual indication that i’ve just plugged in and the battery is now charging. could i have used too much solder?

I cannot answer all these questions without looking at the laptop.

i found that the power jack was not near as broke as yours only loose….slightly. it’s taped down and harnessed very well, so surely it didn’t come loose from the motherboard itself. i kind of wish i’d have super glued the darned thing back and been done with it.

If the laptop base is not damaged, maybe you should buy a new DC jack harness and install it instead of the broken one?

Hi!
well i survived this entire process. I didn’t know you had a tutorial for taking apart my p305d and i actually found it before i started. soldering is probably the most aggravating part. aside from dropping a screw in the tiny hole in the hard drive housing…argh! thought i was going to have to take it all apart again just to get the screw. anyways, i found that the power jack was not near as broke as yours only loose….slightly. it’s taped down and harnessed very well, so surely it didn’t come loose from the motherboard itself. i kind of wish i’d have super glued the darned thing back and been done with it. long story short, i got the new jack in, all parts back together and working great..tested that out first on battery to make sure i didn’t ruin something else in the process…..crossed my fingers and plugged her in…..and……..nothing (the plastic doesn’t go all the way flush from the cord into the jack…but it didn’t when i just plugged it on before all the work just to see how it fits) I got the exact jack that you mention. could it somehow be wrong for the p305d or is this okay to have that little space of the post showing? or is it just enough to not make a circuit and power up? so there’s no usual indication that i’ve just plugged in and the battery is now charging. could i have used too much solder? wires were tightly connected to the jack. i worried that maybe i should cover some of the wire and solder with electrical tape, maybe i shouldn’t have? what do you make of this? i wonder if after all this hard work it was just a faulty power cord. i have no indicator lights on that to be sure. i’d love some advice if you have any and sorry for nearly writing a book here LOL hope you can help

ok so i have just taken the laptop upstairs and plugged it into a socket in my bedroom and it works almost perfectly,

if i move the mouse round quickly in circular motions it only freezes for a fraction of second about once every 10 seconds whereas downstairs i wouldnt even be able to move more than a few mm before it darting off in another direction.

Aaron McAllister,

Hey i did this fix on my l300 all charges ok now. The only problem i have is when i plug the ac adaptor the touchpad becomes very irratic. My cursor goes really jumpy it is extremely hard to use. As soon as i take the ac adaptor out the mouse works smoothly again.

I also noticed that if i put my fingers on the silver part of the dc jack thats visible when charging the mouse goes smooth again. so i end up holding that with one hand while trying to use the laptop with the other.

I have no idea what’s wrong.
Bad soldering? Grounding issue? Maybe the jack is shoring something.
I cannot tell without looking inside the laptop.

deanna,

where do I clip the antistatic mat/and or wristrap? It’s evident on a desktop but I’m not sure on a laptop.

You can attache it to one of the frame screw on the desktop. Somewhere on the back of the desktop.
If you don’t have antistatic mat or wrist strap, it’s not critical. Simply touch the metal desktop frame before touching internal parts in the laptop. It will remove any static from your body.

How do I check polarity? (this is my main question….it seems very important…the other questions i can figure out as i go, so if you don’t have time please just answer this one)

In my example the red wire is “+” and the black one is “-”.
The red wire should be connected to the connector in the middle of the generic jack. The black cable is connected to the connector on the side.
You can see it on the step 6.

Will I have to shorten the jack for the p305d (i noticed some comments where some models didn’t actually require it…if so how do i shorten it?

I don’t think you have to shorten it for Satellite P305D. As you can see on the last picture in the guide, it has enough space for the generic jack.

Good luck and proceed at your own risk!

Hi! thank you so much for going to so much trouble posting this site. Hopefully by the end of the day I will have finished this repair on my p305d. I will be donating too and I hope that everyone else does. If they haven’t shame on them! because you’ve saved all of us alot of money!
This will be my first computer repair. I’ve rarely failed at things like this being a pretty successful do-it-yourselfer and I like to be very prepared and make sure I understand everything before i proceed. I have all supplies, even an antistatic wriststrap as well as an antistatic mat to be safe. so my 3 questions are very basic, but i want to know before i proceed:

Thank you again! and it’s tax season so I will definitely be donating!
