I have a Satallite M30 laptop. When I plug in my Toshiba power adaptor after charging up fully the connection seems loose and now sometimes my computer doesn't charge and shuts down on me. It is odd as the connection in my laptop doesn't move, but the connection from the power adaptor doesnt fit snugly, and yet we tried a universal power adaptor and there was no power. He told me it would be a $400 repair job, I think I am being ripped off! Help could this really be that expensive to fix if it isn't the power adaptor which I don't think it is?

1st : you can check from the power cable charge
2nd : check the adaptor charger if there is a light indicator or not, or you can check with multimeter to check the voltage on charger adaptor, does show the proper voltage for your laptop, you can check at the end of the connection that leads to the laptop.
note : Remember use DC current at Multimeter
3rd : if the adaptor running well, just plug on the adaptor charger to the laptop, dont turn on the laptop power, just see the light indicator with battery / lightning image on laptop, its explained that there is or is not the power current running to the laptop.
3rd.A : if its no power goes to the laptop then your adaptor charger is failed
3rd.B : if is there, there must be a problem with your motherboard, section power / power plugs, why do not want to charge with a new battery.
- if the problem on number 1 & 2, then you can change the power cord and the adaptor charger.
- if there is problem on the 3rd.B then you can go to the toshiba services center for your problem.
So sad to see this problem. I had M30 also and truly nice and reliable computer. For the safety of your data and computer would you please don't plug in your leaked adaptor. Based on your explanation above your adaptor had a leaked transformer inside it, so you could hear a strange sound from it. This cause by dropping your adaptor frequently. For the solution of this problems bring your laptop to a service center or authorize service and ask them about this leaked but when you want a short solution just replace your adaptor and it can solve your problem but remember to use the original adaptor because I believe you don't want to blow your laptop.
This is a middle pin issue, you will find the laptop
doesn't charge either but will power the unit, if the power is
connected, the laptop will hang and use reserve resources, if you
unplug it, the machines performance will dramatically increase.
replace your power adaptor and all will be fine, i have had the same issue.
Try to connect the AC adaptor of your laptop and plug it to the wall outlet and let it charge for 3 hours or more. When you plug it on the wall socket, it won't show the laptop's led blinking since it was totally drained. But after 3 minutes or more, it will start to show the blinking led to indicate charging. When blinking stops led light disappears, it is fully charged and ready to use.
Remember: Do not use your laptop while it is plugged in to save your battery life. When at home, remove the battery while it is fully charged and plug the AC adaptor directly to the wall outlet. It will still work without the battery as long as it is plugged directly to the wall socket.
Hi ! While power off, disconnect the power adaptor. Take off battery.
Plug the power adaptor back and try to start ! Is it running?
If yes, than the power adaptor is OK.
Now shut down and disconnect the power adaptor. Put back your battery and start! Leave it untill you 'empty' the battery. Do not start your laptop.
Plug the power adaptor and do not start your laptop yet. Is there a led idicator showing that the battery is charging ? Does it shows when the battery is full charged (e.g. red/yellow=charging, to green/off charged)? If not, leave it for at least 3 hours. After that, start your laptop (adaptor is plugged) and see if you still have an icon saying charging 99%.
If that is the case, then something is wrong with the battery.
Check your warranty, and replace it. DO NOT OPEN the battery - nothing interesting you will find inside - nothing you can do !
Try this.Your VGA is problem or your battery is fully charge down.so please fully charge your battery atleast 8 hours and then press your power switch.it will on your loptop system.

sounds like you have an intermittent problem with your AC adaptor or dc input jack. Does the light on the AC adaptor light up when you plug it in? If it does then your dc input jack may be faulty. If the light on the ac adaptor does not light then replace the ac adaptor.
This problem has happened to me on several occasions. I found that the connector that you plug your power supply into on the motherboard gets loose. Not making a good connection and like you said needs to be re soldered. Before attempting this, stick a small screwdriver in there and see if it's loose.
If it is, then EVERYTHING needs to come off to get to it. Not a quick project. I suggest you take pictures along the way just in case. Good luck!
