Will not power on

When I try to power it on, the lights will flash and then go off. If the button is pushed a few more times, the cdrom light will come on, and the power light stays on as well as the cpu fan turns on, but nothing on the display. I have plugged in an external monitor to no avail. I have try the function keys, no luck. I have removed RAM, cdrom HDD, try to check if it was RAM but get the same results. I just got it back from Gateway/Acer repair, but now past warranty. They did replace the motherboard and RAM as well as HDD. It was working fine one day until I updated the system and when it rebooted, it shut off and would not turn back on.

As you have enough knowledge to take your laptop apart and remove items to track the problem down, my first suggestion is to make sure that the graphics chip/card is seated properly. Poor re-seating during repairs is one of the most common issues. It may have been seated enough to work for awhile. When you updated the system was it a BIOS update or BIOS and graphics? Often when graphic cards are updated a few of the bugs slip through. A good indicator of that is when you boot your laptop do you see anything on the screen at all? When your booting the O/S runs your grpahics as vanilla display until your actual driver is loaded. If at all possible, and if you have a copy of your O/S's install cd, try and boot from that cd. If you still can't see anything, then you could pretty much be assured that your graphics unit has died on you. The fact that you couldn't see anything on an external monitor probably bears that out.

Try the reseat, try and boot from your O/S's install cd. If everything fails it would be a good indicator that your graphics unit has given up the ghost.

MY FIJITSU inverter is not working correctly, the timer light is flashing continuously and the timer lights flashes 5 times can anyone help pleawe


fujitsu is a good brand.
try one of these two things:

Turn the unit off then on again. After that press test button on remote control (rear side) and look how many times now operation and timer LED flashes. Note that. Then press MANUAL/AUTO button on indoor unit until you hear 3 beeps from buzzer. That will erase error memory.
Switch off and than on unit and see if indication repeat or it is gone. If it is gone, keep using your unit.
If it is repeated post your notes here.

OR+++++++++++++++++++++FOR OTHER MODELS

5 x Operation flash and a constant Timer flash indicates an outdoor unit control error. With this code flashing on the indoor unit, you need to point the remote at the unit and push the test run button. The flash pattern will change to a continuously flashing Operation light and a number of flashes of the timer light which gives more detail on what the error is.

To get the unit to try to restart you need to push and hold the manual/auto button on the indoor unit for a few seconds then reset the mains power supply but leave it off for a minute or so for the unit to power down completely. If you are going to try this make sure you make a note of any error codes first if you have to get someone out to look at it, it will help them a lot.

Acer aspire netbook wont turn on flashing white light on power button


Did you try to flash a new BIOS? If so, you might be in trouble and
need probably to reflash the new BIOS. (Look at Acer site for info).
But anyway try:

1. Push and hold the Power On switch for 4-6 seconds.
Try to Power On again.

2. If this does not work, do a Power Reset:
- Disconnect powersupply cable and pull out the battery.
- Hold the Power button for 60 seconds a few times.
- Place the battery and powercupply cable.
- Try to Power On.

Lights are on but mouse doesn,t work.Inland wireless mouse and keybord. Keyboard works great.


Check with fresh batteries.. Did you sync the mouse with transciever? Push tiny button on transceiver, (maybe hold for few seconds) light flashes quickly.. then push tiny button under the mouse, light stops flashing. Try few times, maybe otherway round. If still not work consider defective.

I need to know how to reset my printer, I 've cleaned the pads, but nothing... Thank you in advance...


Power down the Canon Pixma IP4300. Once it has shut down, leave it off for a few moments.
Hold down both the "Resume" button and the "Power Button." When the printer begins to restart, release the "Resume" button but continue pressing "Power."
Push in the "Resume" button twice, then let go of both the buttons. In a moment, a green light flashes a few times.
Press the "Resume" button four times once the green flashing has finished.
Push the "Power" button again until the printer shuts down. Wait a few seconds, then press the power button again to restart the device. The Canon Pixma IP4300 will now function properly. for more information http://www.fixyourownprinter.com/forums/printer/67824 hope this helps you.
