Could my USB ports be ''burned''?

[zebedeu]

Ok,this is my first time posting on this site so correct me if created this new thread wrong but any ways ..my lenovo g570's USB ports dont work anymore and next im gonna tell you exactly what happened.
About a week ago my uncle brought me a camera but unfortunately the charger was broken,so i decided to charge the battery directly with an USB cable and so i did i cut the USB cable,hooked the wires to the battery and when i plugged it into the laptop my USB ports stopped working and this error popped out

i didnt know what to do so i clicked the message followed the instruction and got my USB ports running again,so i decided to do it again but this time i unplugged the mouse then plugged the USB with the battery in the laptop and it worked nothing popped up this time,so i charged the battery for like 15 minutes and then unplugged it and it charged really good,the camera was working fine,now the problems with the laptop started,i have 3 USB ports and only the port that i used to charge the battery was working the other 2 are DEAD,but i didnt do anything about this problem, i had one port thats all i needed.So the next day when i started the laptop the 3rd one started to make problems like it kept disconnecting when i moved my mouse and connecting back when not moving the mouse,but for some reason ,in safe mode it worked with no problem until the last port stopped working BUT when i plug my mouse in the port the light starts for a split of a second,then shuts down.
I already tried to uninstall the drivers from the device manager and reboot but it didnt help,i also disabled the USB selective suspend setting and didnt do anything,and also to remove the battery and the charger and to hold the power button for 30 seconds but it didnt do anything i even let it over night ive heard something about resetting the CMOS or something to remove a battery for 30 second and then put it back in but i couldnt find any battery on the mobo so..yeah...hope someone can help if not imma have to take it to a repair shop or change the mobo i guess..

You probably burned something on the mobo, you cant just connect wires directly to the battery, if your camera has USB port then you should just put the battery in the camera and charge it that way because there needs to be some sort of controller chip between the battery and USB port, for example if you want to charge your phone using USB you dont take out the battery and cut USB cabel and connect wires directly to the battery, you should connect usb cabel to the phone and charge it that way.

If your charger was broken and you still have warranty for your camera you should just send it to repair shop and they would fix it, by connecting wires directly to the battery you can damage both USB and battery, battery may even explode if its overcharged because there is no control chip and hardware to stop charging when battery is full.

Thanks for reply and yes youre right if my camera had usb port i wouldnt have charged the battery this way but my problem is that my laptop's usb ports are not working,i had a sony vaio before and i used to charge my phone's battery directly with an usb cable and it never happened something like what happened with this lenovo laptop though

Hi, what you did when charging the battery from the camera, you have overloaded the circuit that powers the USB, in your case the APL3510 circuit. This chip should be replaced.

Well thanks for telling me that but im not sure what chip you are talking about,but can i change it myself or do i have to take it to a repair shop?

If you can solder a SMD chip, sure you can do it yourself, but if you go to a repair shop, if I have the right information, you can tell them to verify the output of the U29 chip, they should read 5VDC.
