 and try sir ....

memory cards need to be reseated they are losing connection and the computer looses video due to a connection on memory cards.

Just check the connection of your cdrom on the My computer if they have appear. If the cdrom was display in the My Computer just clean the cd lens of that cdrom. Remove the cdrom from your computer and open the cd lens then clean it by the piece of cotton and add a small amount of alcohol then rub on the cd lens. After that insert back the cdrom then try to power on your computer and if the problem are the same not solved. Just replace the cd lens of your cdrom, But if the cdrom was not display in the My Computer just check the connection inside if the power supply of the cdrom are connected to its back.

The Acer 5920 comes with two options to connect and display the desktop onto a TV.

The First Option is the HDMI port which you can identify by looking here http://en.wikipedia.org/wiki/HDMI

The HDMI cables cost around $14 - $20 at Target or Walmart

You must ensure that yourTV has an HDMI port or you will not be able to connect to it.

Also, the regular 5920 does not have an HDMI port, but the 5920G does, so check your model on the bottom of your laptop to be sure.

The second option is S-video, you can see that here http://en.wikipedia.org/wiki/S-Video

Cables are retaltively cheap, but be sure to check the connections to ensure the pins match the port.

1. Remove laptop battery, optical drive, hard drive and ram. Remove external peripherals as well.

2. Make sure AC Adapter is not yet connected to the laptop. Pressand hold on the laptop’s power button for 10 seconds to drain the powerflea.

3. Connect the AC Adapter for laptop to a known good power outlet, check ACAdapter power LED if it is on. Try to sense if AC Adapter is not makinga bit of noise when it is plugin to the wall power outlet.

4. Connect now the AC Adapter tothe laptop. Check if AC Adapter LED stays on when it is connected tothe laptop. If the LED stays on means the AC Adapter is fine. If the ACAdapter LED turned off check the AC Adapter pin that goes to the laptopAC socket if it is loose.

5. If AC Adapter stays on after connecting to the laptop try topower on laptop. If no power LED comes on then this is motherboardproblem.

6. Before replacing the motherboard there is one checking needs todo. If you can open your laptop bottom part then good, do this whenlaptop is not connected to any power source. Try to reseat the laptopCMOS battery then try to power on laptop after, if still fails thenreplace motherboard. I hope this helps.

The drive is probably loosely connected. Powerdown. Remove thebattery. I would remove the chassis cover over the HDD, PULL IT OUT, and reseat the HDD firmly.You can also gently tap the drive perimiter several times. OR you can make a WDDiag CDROM, boot the machine with CD, and a program will diagnose you drive, and probably fix it.

Your power supply or regulator in you laptop has gone south. sorry no quick fix for this one. It needs repaired and would include tracking down soldered connections.

sorry to tell you this.

hi friend,

operating system of your laptop has crashed. you have to reinstall operating system. entire data which was stored on desktop, My documents will be lost.

Turn on your laptop and open DVD rom. Insert bootable CD which you might got with laptop. then it will start itself. and follow the instructions given on the screen.

Your friend,
Anil

Try the firewall settings, turn off and if you can connect than thats the problem, failing that then try the security tab and set to lowest and bring up the level until you can't get on then knock back so you can. Also, copy all the settings from the computer that can connect to the one that can't.
