My laptop wont start up even when connected to AC..was working very well prior to connecting mouse to USB port..AC adapter not a problem since light is present at point of connection with laptop. read somewhere that USB port create some issues with AC circuitry. When "power button" is pressed, blinking light can be seen on "AC connected" LED light... this issues all came about because i replaced old battery with new and i am trying to recharge my new battery the 2nd time ( 2nd cycle - charging and re-charging). the first cycle was okay ...do i need to bring my laptop to a repair shop to check the AC circuitry?

    my laptop is HP dv6700....

  • rmespinosa20 Sep 13, 2010

    Ive tried connecting the Ac adapter with the old and new battery in place..but still i cannot see the charging light...how ever when i pressed the "power button" ( for both instances when the old and new battery in place ) , i can see the charging light "blinking" ...but laptop still doesn't start up... is it an indication that the charging circuitry is good.?..Also i observed that the "indicator light" at the point of connection between the cord of the AC adapter and the laptop is also "on" when connected to power outlet......at present i have no way of checking the voltage at the terminals.....

Even I changed my VAIO's battery just a week back. No issues. I just inserted the new battery and powered on the VAIO. It worked and then I connected the charger as the battery was about 40%. And has been working ever since for about 10 hours a day. In your case the charger is fine. The battery is new. Try powering on with the charger disconnected. And press F2 at boot up to enter the BIOS. Or on second thought, let the battery be fully charged the second time. Then power on the laptop with the charger disconnected.

You may need to have the circuity inspected, if you remove the mouse from the USB port does it function normally? It could be just the one port causing an issue, which I've seen before.
If it isn't working at all now, regardless of the mouse being plugged in, then yes you definitely need to get it checked out in person. If you need a recommendation on where to go for help please reply with your ZIP code and I will give you at least one or two shops in your area that will address the issue. Thanks Tim

It is possible that the battery that was replaced was having an inernal short and could have damaged the charging section.
So remove battery and test the voltage on the new one , replace old battery and connect adapter to see if the charge light comes on or the laptop works. If so the new battery is faulty.
If not remove off the batttery and check the voltage at the terminals in the laptop . If voltage is not present then the charging circuit is damaged and you must take help from your dealer to help out.
If voltage is present then the battery must be checked once again.
There is no relativity that a USB can damage the laptop unless the connected USB is faulty, shorted or a not recommended product so as to take the full supply voltage from the laptop to be shorted/powered in excess limit.

Advent modena m200 will not turn on or charge.


Connect the AC power adapter to the laptop and confirm that the AC power indicator is on (I wish you stated the brand of laptop). If the AC power indicator is not on, try and get a working AC power adapter for your laptop and connect it to your laptop.

With the AC power adapter connected, you can power on your laptop. If the laptop powers on from the OS you can see if the Battery is charging or not.
If the laptop does not power with the AC power adapter connected, then the power port of the laptop is bad.

However, if all these are okay and the battery still does not charge, the battery is faulty and will need to be replaced.

There are 4 possible ways in my awareness...
Method 1: Resynchronize your device with the receiver To resynchronize the mouse or the keyboard with the receiver, follow these steps. Note When you synchronize the mouse or the keyboard with the receiver, put the device near the receiver and put any other wireless keyboards and mouse at least 6 feet away.
  1. Press the button on the receiver, and then verify that the light on the receiver starts to blink.

    Note Some newer Microsoft devices are permanently bound to their receiver and cannot be reset. If your device does not have a button, skip to Method 2.
  2. If a dialog box appears on the screen in several seconds, follow the instructions that appear on the screen. Otherwise, go to the next step.
  3. Press and release the Connect Channel button on the bottom of the mouse or the keyboard.
  4. Check the green light on the receiver. A steady green light means the synchronization was successful. If the problem persists, try steps 1 through 4 again.
  5. For the Wireless Notebook mouse: This issue can occur if the micro-switch on the bottom of the mouse is not released. Use a pin or a pen to try to release the button if it is depressed.
The following example shows the buttons to push to synchronize a wireless hardware device:

USB keyboard and USB mouseIf the USB cable is currently connected to a USB hub, disconnect the device from the hub, and then connect it to a USB port on the computer. If your device is already connected to a USB port on the computer, try to connect the device to a different USB port if one is available.

Note Only one USB connection to the computer is required, even if your device has two USB plugs. If the problem persists, disconnect other USB devices and connect only the USB plug from the receiver to a USB port on the computer. PS/2 devices Warning If you have to change a PS/2 connection, shut off the computer, make the changes, and then restart the computer. Do not plug a PS/2 device into the PS/2 port while the computer is running.If your devices are connected to PS/2 ports on the computer, verify that you have the following configurations:
  • Verify that the USB plug for your mouse is connected to the green USB-to-PS/2 adapter and that this adapter is plugged in the mouse PS/2 port on the computer. The mouse PS/2 port on the computer may also be green. If you are not sure which PS/2 port is the mouse PS/2 port, see the documentation that was included with the computer.
  • Verify that the USB plug for the keyboard is connected to the purple USB-to-PS/2 adapter and that this adapter is plugged in the keyboard PS/2 port on the computer. The keyboard PS/2 port on the computer may also be purple. If you are not sure which PS/2 port is the keyboard PS/2 port, see the documentation that was included with the computer.
If you have to change your configuration, shut down the computer, make the changes, and then restart the computer. If your mouse or keyboard has both USB and PS/2 connections, try using the other connection. PS/2 keyboard and USB mouseIf you are using a wireless mouse with a USB connector and a PS/2 keyboard, verify that the USB mouse is plugged in a USB port on the computer and that the purple keyboard PS/2 plug is connected to the purple PS/2 port on the computer. If you have to change the PS/2 connection, shut off the computer, make the changes, and then restart the computer. Method 3: Reinsert the batteries or install fresh batteriesBoth the wireless keyboard and the wireless mouse rely on AA alkaline batteries for power. Remove the batteries, and then insert them again. If the problem persists, install a fresh set of batteries in the device that you are having problems with. Method 4: Check for interferenceItems such as wireless routers, radios, cell phones, desktop fans, fluorescent lights, and large metal objects like computer cases and metal furniture may interfere with the signal of the keyboard. Try to keep such items away from the keyboard, and check the behavior of the keyboard.

Do not put the mouse or the receiver near any electrical devices, especially transmitters such as cordless or cellular telephones or other wireless mouse devices or receivers. A distance of at least 8 to 12 inches is recommended. Do not put the mouse or the receiver on metallic surfaces or objects, especially long metallic rails or cables. We recommend that you keep the mouse and the keyboard a minimum of 3 feet from metallic objects.

The connection on the rear of the hub should go to a USB connection on the laptop, not a PS/2 connection. A PS/2 to USB adapter is used to connect a PS/2 keyboard or mouse to a USB connection.

I plug in my mouse to my laptop and it wont work, the bottem doesnt even turn red.. when i connect it all it says is usb device not recognized, it worked last night and tonight its not.


Try disconnecting the mouse from the usb port and reboot the unit.
Now, on your touch pad, top left blue led is let showing it is functioning. Press the center button next to the led, which will shut off the internal mouse.
Plug in your mouse to a different USB port and the unit should see the mouse.
If not and the mouse does not light up, replace the mouse.
You may have had a conflict with the internal and external mouse.

USB drives Not working


this problem seems mostly with the usb mouse, the best solution is to plug the flash drive in one port and usb in other and restart the computer generally this always works but if it wont work then the best thing is i also did that, buy a 4-port usb hub and connect it with laptop and connect your usb mouse with this port not directly to your laptop and when you like to use your flash drive plug it in the laptop.
this is working with be perfectly and i hope it will do the same at your side.

To clean the lens of an optical or laser mouse, follow these steps: 1. Use a dry cloth to clean the bottom surface of the mouse. 2. Check to see whether the mouse functions correctly. 3. If you see dust on the bottom of the mouse, use a can of pressurized de-ionized air to blow away the dust on the lens. 4. Check to see whether the mouse functions correctly. 5. If the pressurized air canister is not available, blow dry air on the lenses by using your mouth one or two times. 6. Check to see whether the mouse functions correctly. 7. If these steps do not resolve the problem, use a cotton bud to clean the lens without scratching it.
