Question about Computers & Internet
The dc power socket on my laptop top is loose, so power cuts off ever so often. My battery needs replacing. Is the any other way I could power my laptop either through the usb port or a additional battery that can be charged independent of the laptop. Would appreciate your comments.
I know you've either fixed your problem, or thrown the laptop out(still a "fix") but for posterity, and for anyone with a similar problem...
There are two answers, depending on your laptop.
First, NO, there is currently no way to charge your laptop battery by putting power into the usb port.
There ARE commercial external batteries. sadly, they will connect to your failing power-socket.(see http://www.laptop-battery.org/Power/External-Batteries/ENB003L.html)
If your laptop has a external battery charging dock, for spare batteries.... you could go that route.
you'd probably still want to follow the last suggestion.
GET IT FIXED!
Seriously... anyone with fairly good soldering skills can probably fix that powerjack. It probably pulled/pushed the traces off the main board and will require superglue, solder, and maybe a bit of fine wire, to fix. The biggest obstacle will be the dissassembly, and proper reassembly of the laptop case. It'll take a while, but once fixed, should return your laptop to 100% functionality.
I have saved 3-4 laptops with this technique. One, I even swapped the power jack to a more common size. This was to allow the use of a non-proprietary power brick(the original had fried itself).

I don't recommed doing this but technically you can power SOME laptops via their USB port. However, you can NOT charge the battery this way. You will need the ENDURANCE car battery booster box with USB function. You will need a MALE to MALE Type A USB cable - only available on Internet - RadioShack et al does NOT sell them. I do NOT know what will happen. Not even sure the power switch will control it either. May come on as soon as you plug it in I don't know. I think this method bypass the internal power conditioning circuitry so It has to be a battery which is more stable than power mains..Some manufacturers say don't do it but I think it will work as the USB power circuit is connected to main power bus of laptop. Your internal digital cicruitry, display, and drives actually only require 5VDC not 12-19V which is stepped down internally to 5V. The ENDURANCE box has enough current to handle the laptop's current requirements. I ordered my USB cable today and will try this on two busted laptops I have. Good luck!

I can suggest to try to put out old power socket and buy a new one
if you can do it pay attention to respect the polarity of older socket
that will be + to + and - to - - i think it is not difficult- delfo

Best and cheapest solution I have found which doesn't cost all that much was just to buy a replacement power adapter off Amazon. If you can stomach the 3-5 day wait, in the long run you won't ruin your laptop, you won't over amp your circuit board--which is a death sentence and i got mine for $19.95 US Dollars. It works great and notice no difference between that and the original that came with the laptop that they want $99 at Radio Shack or $119 at Toshiba...so there you go!

is just as good of an answer as any other answer here in regards to the question that was asked. the person didn't ask how to replace the charging socket, or where to buy any OE replacement part. they simply asked if you can turn on and then keep the laptop powered through the usb port (which would be nice if someone has a solution considering we have "always on" usb ports now and the old excuse was that there wasn't voltage to usb when it was off...") OR is there an adapter to charge a laptop battery independently from the laptop (which there are but usually expensive, mostly found only in the corporate world, and are made to charge a "battery" of batteries at once, lol) you could maybe find your batteries pinout schematic and make a cable for the battery itself, but i'm sure that's way more complicated compared to just plugging a usb cable and power cord in.
