Revised Question about shorted USB port (short to ground)

I connected a Lipo charger to one of the right side USB ports and it caused a short to ground which has caused all USB ports to stop working. I am also getting an error that the Audio has stopped working. I found that the latitude has this "Precision M2400 IO Circuit Audio Board for UMA Motherboard Integrated Intel Video - D810N" board and it has the USB ports integrated onto it that was shorted. What are the chances that replacing only this board fixes the problem? I thought that it was the mother board but now I'm thinking either this card or both it and the MB need replacing.

SOURCE: memory module

Your motherboard supports 533MHz memory modules, no more. If you put anything higher in, it will work, but only at the speed of 533MHz, so there's not much point in aiming any higher. Just make sure what you're buying is a DDR2 533MHz memory module, and it's best to get them in increments of 2. If you have 4 slots on your motherboard, get another 2x512MB modules of RAM. If you're running Windows Vista, it might be worth considering 2x1GB modules. I think that pretty much covers your question, if you have anything else to ask, feel free to reply.

SOURCE: USB Port Malfunction

There is no power option in XP to shut off a USB port to preserve power so dont worry about that. I would try to use a different USB device such as a USB Flash Drive or printer etc. to test. If the flash drive for instance does not say it is disconnected after 2 minutes, then you know that the problem is with the wireless card. If it does the same thing as the wireless card, then you know that its not the card. I would say it would most likely be a motherboard at that point which becomes a rather expensive problem. Hopefully this helps!

SOURCE: Integrated Ethernet Port Fried/Trying to Reformat

in the Dell BIOS you can disable on-board LAN by going into the BIOS (hitting F2 at the Dell splash screen), scrolling down to Integrated Devices, and then selecting "Network Interface Controller" (keep hitting left/right until "OFF" is selected.)

Save changes and exit.

SOURCE: replace broken usb port on dell latitude laptop

You will have to take the machine apart somewhat, or at least to the point of being able to disconnect and remove the usb port. Here's a link to the D600 service manual download. It will guide you through the breakdown process.

Unless you are pretty computer savvy, you'll want a computer pro to replace teh motherboard.

I got a new transcend USB jetflash drive 16GB, but my system not showing any response towards it, what shall i do..??? is to download a software for it...??


Flash drives do not need a drivers (plug and play). There are several possibilities:

1. Assumptions: USB port error, computer drivers normal, normal flash drive.
Solution: insert a flash drive into another USB port. If the USB port 1 is not detected, insert flash drive into a USB 2, USB 3 or USB 4.
2. Assumption: normal USB ports, computer driver error, a normal flash drive
Solution: reinstall the chipset drivers, or USB.
3. Assumption: normal USB port,
computer driver normal, flash drive is broken
Solution: try to insert the flash drive into another computer. If the flash drive is not detected, it means your flash drive is damaged.

Solution to determine the cause of damage:
1. If you have a USB mouse, use the mouse to check the damage to the USB port. Example: connect the mouse to the USB 1, USB 2, USB 3 or USB 4. If every USB port, mouse is detected, the conclusion normal USB port
2. To check your computer's drivers, right-click My Computer - Properties - Hardware - Device Manager

10_13_2011_8_27_15_pm.jpg

3. If points 1 and 2 are normal, the possibility of flash drive damaged.
Because the new flash drive, flash drive is most likely normal. Based on experience, cause damage to the flash drive is a USB port is dirty. The USB port is dirty, can cause short-circuit flash drive. The characteristics of short-circuit flash drive. When inserted into a USB flash drive (about 5 seconds), the temperature of the flash drive become extremely hot. If there are problems like this, immediately unplug the flash drive, to prevent permanent damage.

I hope this information helps.

My two right hand usb ports are not working!


Hi,
Three questions that will resolve the issue:
1. Did the printer work? Was it working till the end when you unplugged it?
2. Hopefully you have tried the same devices in other ports and they are working. Else the device maybe faulty.
3. Is the device manager showing any components without drivers?

If the above three points are ok, you may have the seldom case of USB short circuit. USB has power lines. They normally dont short so easy - but things happen.

I would say - ignore the ports. Buy a cheap new hub and use it in one of the working ports. That is your best and cheapest solution.

Whenever I insert my pen drive into my pc,it restarts computer. what is the problem ?


if this is only happening on 1 usb port, there is a short in that port that is causing you PC to shut down. Your motherboard BIOS is probably set to reboot on power loss which means it will boot right back up if it shorts out.

If it happens on every USB port then your pen drive is faulty and I would refrain from inserting it anymore before you damage your hardware.

If the pen drive works on someone elses computer, then it sounds like the SOUTHBRIDGE chip (chip on motherboard that controls USB, PCI slots, firewire ports, etc) is going bad or is faulty.

Hardware problem - not booting into windows


One of your usb ports is either damaged or has an object stuck in it causing a short. Unplug all usb devices and look at each port. Note if one looks slightly different from the others. There is a plastic tab that fits into usb plugs. If this tab is bent and touches the side of the port, it can cause the short. If this is the case you may be able to either clean out or bend back the bent tab.

i dont see how a usb port can actually be related to your sound but maybe the best solution right now is to simply replace your usb port as it might have been damaged by your external usb keyboard
