Help my extensa 4420 does not illuminate

I have a laptop Acer Extensa 4420 2009, that does not illuminate.

He sat for 4 months unused. Don't work on battery power (15 min max)

Finally bought a new battery.

When I press the button start is there no response.

I checked the power supply: good 19.1 V dc

I have a new battery.

When I plug in the power supply, I get the fire A GREEN on the incicator of battery charge.

I tried the static reset: remove the battery & power supply, press on & hold start for 30 seconds.

I deleted & reset memory modules RAM (2 x 1 GB).

I opened back and reinstall all connections of Ribbon & connectors, hard drive etc.

Last fall it's intermittent start up, I replaced the cmos battery, that fixed.

Could use some suggestions where to look next.

Problem SOLVED:

I did more reading. Find more on the reset procedure.

(1) I unpluggged the battery & left overnight.

(2) in a hurry & has held start button for 1 mniute.

(3) to replace the battery (new) & start-pressed: the UNIT POWERED UP!

I am trying to load updates.

  • I need help, its frustrating me! network discovery does not illuminate.

    my network discovery does not illuminate. Whenever I try to turn it on I get an error message that says: (the specified service does not exsist as an installed service)! I need to elp, its frustrating me! I have windows vista.

    Hello

    Did you change your computer?

    Method 1:

    Based on the network location you choose, Windows affects a State of network for network discovery and opens the Windows Firewall ports suitable for this State.

    Step 1: We recommend you to check if the elements of network discovery are enabled in Windows Firewall. To do this, try the following steps.
    1. click on start, type firewall and then click Windows Firewall with advanced security.
    2. click on rules of incoming traffic in the left pane and select the (SSDP-In) network discovery and network discovery (UPnP) - in the list.
    3. click on rules of outgoing traffic in the left pane and enable network discovery (SSDP-out) and the discovery of the network (UPnP-Out) in the list.
    4. apply the changes and check the result.

    For more information about network discovery, see this link:
    http://Windows.Microsoft.com/en-us/Windows-Vista/what-is-network-discovery

    Step 2: Check the status of the following services: browser, TCP/IP NetBios support.
    1. Click Start, type services.msc and press to enter.
    2. from the list of services, double-click the service computer browser and TCP/IP NetBios support.
    3. change the startup type to automatic and start the service.
    4. apply the changes.

    Method 2:

    Now we go ahead and try to enable the discovery of the network on your computer and check for the issue.

    Network discovery is disabled by default for public networks. Changing a network location type to home or work is the best way to turn on network discovery. To learn how to change a network location type, see Choosing a network location. To enable discovery manually, follow the steps below.

    To turn on network discovery

    1. open the network and sharing Center by clicking the Start button, clicking Control Panel, clicking Network and Internet, and then click Network and sharing Center.

    2. If network discovery is off, click the arrow button expand the section, click turn on network discovery, and then click on apply. Need administrator permission if you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    I also suggest you turn on discovery of the network link and check.

    Enable or disable network discovery

    Hello

    LED flashes orange?
    If you mean the DC-in LED if it flashes orange if the output voltage of the adapter is abnormal or if power outages.
    If you mean the Power LED so it flashes orange while the computer stops if you select sleep mode.
    If you mean battery LED if it flashes orange when the battery reaches a low battery indicator.

    I think you should check if the AC adapter has no malfunction and provide enough power.

    I think you should also try another solution that I found in this forum.
    So to remove the battery and unplug the AC of the laptop and wait form (10-15 min) then several times the battery and connect the AC to the laptop and try to start the laptop.
    Eventually, it helps.

  • Satellite A300D does not illuminate

    Toshiba Satellite A300D does not illuminate

    The battery light is red when it is plugged in with the light of the white plug

    When I press the power button it lights up two other fires, and one that looks like a sheet a4 fact paper.it a vibration when turning it on also.

    Any help would be greatly appreciated

    Disconnect the power adapter and remove the battery.
    Leave the laptop unplugged and then hold down power button / stop along 30 sec.
    Then reconnect the two parts and check how the unit works.

    In which case nothing would be visible on the screen, try replacing the RAM modules. Perhaps one of the modules is the troublemaker
    Otherwise if the RAM modules are OK, the problem could be linked to the motherboard.

    If the WLAN led does not illuminate after that you have activated the WLan switch there is something wrong with the hardware.

    In this case, you can do many things to get this working again, but you can try to remove the adaptor AC/DC and battery. Wait an hour and reconnect both devices and try it.

  • surcurity essentials does not start, and the windows firewall does not illuminate

    Hello

    I have a problem, he seems to have had a virus on my pc. Essentials of security does not illuminate and the windows firewall will not also turn on, I tried to use the tool to "fix" windows and it doesn't solve the problem.

    the original virus seemed to rename its self as a program existing and renamed the oringinal by a space in the name, for example "adobearm.exe" became "adobearm .exe" there is a space before the dot.

    The virus called his free adobearm.exe icon because it is a yellow / orange with a letter H, at the Center

    different file name her seemed to be part of the virus included "ag7yl5x8.exe".

    If you tried to close them in the task manager that they just either came back or a different file name would appear in the list.

    I also couldn't do a windows update, but I think as the tool to 'fix' as cured this problem.

    Can someone help me please.

    Thank you
