Question about Computers & Internet

1 Answer

Okay, I've just joined and I'm hoping someone can help. So tonight, I plugged in my iPhone to the left usb ports (as I always do before bed)(The right ones are disconnected for some reason, I think the wires are broken). A few minutes later a pop-up down the bottom said something about the ports not working any more. I love this laptop, and don't want to replace it or pay heaps to get it fixed. Any help is greatly appreciated :)

I expect the iphone has overloaded the USB supply. The current the ports can supply is limited and will stop working if overloaded. Use a powered USB hub or the iphone charger. Your motherboard may need repairing now.

SOURCE: My laptop won't connect to wireless internet...

It seems the two oval lights on the front of the Acer TravelMate 3003LCi are not only lights to indicate WiFi traffic, but also buttons to turn the WiFi radio on and off for security reasons. If you press and hold the left side button for 3-5 seconds it should turn back on the WiFi radio. Windows XP (and maybe other OS’s) have a power saving function that turns the radio off when not in use to save the battery, so you have to use the buttons to turn the radio back on. Seems like a pain in the @$$ to me, but it’s a clients laptop not mine so he will have to live with that.

I hope this helps someone so they do not have to go through the frustration of trying to figure out why the radio has been turned off.

SOURCE: Computer not recognizing any usb devices

Well, appears that your configuration can handle 4 GB of memory. I checked the Acer website for upgrades for your model, and nothing appears to jump out which could solve your problem. A few appear to be possibly helpful, but some are for XP, not Vista. Upgrading "launch manager" might be a good thing.

However, Belarc tells me that on my Acer 5630 i have listed under "Bus adapters" the following:
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C8
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C9
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27CA
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27CB
Intel(R) 82801G (ICH7 Family) USB2 Enhanced Host Controller - 27CC
And, under "other devices", i have a USB Root Hub (5x). Obviously, the two match. I go to device manager to check them out, finding them under 'univesal bus controllers", to see whether they are all working properly, and and they are. In addition, opening "system devices" reveals something called a "plug and play software device enumerator", and that checks out to be working fine as well. Check your equivalent out to see if you find a problem to fix. Hopefully you will. Let me know how things go.

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.

SOURCE: Can I power my laptop through th usb port

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

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.

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).

Can't turn on my mp3 player. I have tried to hold the volume buttom but it does not turn on at all.

what type of mp3 player ?

Charge your MP3 player.

The battery might just be dead, in which case letting it charge for a few hours corrects the problem.

Plug the USB data cable into the USB port on the MP3 player and insert the other end into one of the USB ports on your computer.

In a moment, the computer states that it has detected the removable device.

Sometimes the MP3 player needs to update itself, and it can only do so while connected to a computer.

When the MP3 player detects the computer, it attempts to connect to the Internet and retrieve any system updates available for the device.

Replace the battery.

The battery is usually the first part of the MP3 player to go (especially after excessive use). Although you can manually change the battery on most MP3 players, you need to send your

Apple products (iPod, iPod Nano, iPod Touch, iPhone) into the company so they can change the battery for you.

Purchase a new MP3 player.

If your MP3 player has received any sort ofwater damage, it is not going to turn on at all and there is nothing you can do to fix the issue.

hope this helps

I plugged my Philips 4GB GoGearVibe mp3 player into my computer to charge but i am not sure if i plugged in all the way. This has happened before where the battery died but came back when my dad charged...

if you are charging via usb make sure you have the computer (if its a laptop) plugged in and if you are using a pc make sure your using one of the usb ports on the back as some usb ports will not carry the 5v needed to charge your player.

I have a Samsung HM060HI hard drive from my laptop, The laptop is wrecked, I have removed the hard drive... Is there any way of getting my data (pictures and files) from the hard drive by a lead that joins...

You can always use an external Hard drive enclosure whose SATA interface communicates with your computer using your USB ports... 1. Purchase/borrow the enclosure 2. Insert your Hard drive 3. Plug into your USB port 4. let the drivers install and begin migrating your data
I hope this has been informative...

Usb port refuses to recognize plug in hardwares,

You can check from the Device Manager and see if you can enable it from there. Right click on your My Computer and choose Manage. On the left panel click on Device Manager. From your right, expand the Universal Serial Bus controllers. Right click on each on the list and choose Enable.

Also so you can go and check on your BIOS settings and see if the USB port is enabled.

Goodluck and hope this helps.
