Question about APC Computers & Internet

1 Answer

Hi, I plugged in unit and continued to get a battery not connected in the LED window. After letting it run for 2-3 hours, I selected to power down the matrix unit. I noticed hearing a fan about an hour later and went into the office to check it out-fan was running on the bottom unit. Now I can not get the LED screen to show anything on it. I though it might be cycling process. after trying for 2 days and no success I am at the end of rope and can over ride by turning it off at the circuit breaker. Really trying to find out the problem

LG 17LX1R flashing red LED - TV won't power up


Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

First time charging up of archos 5,it has now been charging for about 14-15 hours. but the green light did'nt blink yet. it says after fully charge, the green light blinking. what can be the promlem about...


@wilkerwkocer 

On an Archos, battery is fully charge when the CHG LED light is flashing, while that light is ON all the time, the unit is still charging.

Now, in order to charge your Archos you must leave it on Suspended mode, by holding the Power button for about 4-5 seconds until it says "Suspending", DO NOT leave it on completely "Shutdown" mode, or your battery will never charge, and you are also risking the life of your battery by doing so.

So in other words:

1) On a PC via USB it should take around 8 hours to charge, while connected to an Archos mini dock, battery dock, or DVR Station, it should take around 3 hours to fully charge.

2) Leave your unit completely "Shutdown" (hold the Power button and wait 10 secs. or so until it says "Shutting down" and let it go off.

3) Connect it to your power source, either USB on computer, or external charging device as mentioned above, it will come back on, the two LED lights CHG and Power will come on, leave it like that, and after a few minutes the unit will go into Standby/Suspended mode by itself, and there is when you are charging your battery the right way.

3) Wait 8 hours if connected to your PC, or 3 hours if connected to an external power supply (as described above). If still after being in suspended mode (not completely off) your CHG light isn't blinking after the 8 hours on PC, 3 hours on external power supply, then suspect your battery is defective.

In that case, if the unit is still under warranty contact Archos, if it is out of warranty. If it isn't under warranty, you can buy a replacement battery on eBay and either replace it yourself, or find someone with the technical skill to do it for you.

I hope this helped you.

My TOSHIBA MINI NB205-n313/9 10.1 inch net book will not turn on


Hi,
The laptop is not turning on?

Remove the battery and try boot the machine on AC power only. If the computer starts up turn it back off, reinsert the battery and try to boot the computer again.
If it still won't boot with the battery inserted then i suggest you send or take the computer back as there is a hardware problem.


Regards.

Power problem - led shows the ac plug is in - battery does not charge - can not run laptop on ac adapter - what is causing this problem


Hi,
The connection to the power supply inside the Pc is or has gone,
because your using the connection 1000 times a year, it faulters, and fails.

$150/$200 to get repaired.
Strip out the laptop solder connection back up,
rebuild, very common problem.

Regards
Richard.

Dead Creative Zen M


Usually this problem is due to the firmware. When the firmware is updated to version 1.62.02, this problem usually will be corrected. The older firmwares have problems in recognizing the battery and allowing the battery to power the unit.

You will need a wall/AC charger for the operation. Plug in the wall charger and USB cable at the same time. Your Zen should power on when connected to direct AC power via the wall charger. Once it is powered on, connect the USB cable to your computer. Then begin the firmware download.

If your Zen does not power on when connected to the wall charger, your unit is dead and its time to replace it or get the motherboard replaced via one of the Repair services offered on this website.

If the upgrade button on the firmware window is not available, it is also time to replace your motherboard due to corruption of a chip on the board.

Try this, with laptop removed from docking unit:

1. Press and hold the laptop power button down, for 10 seconds.
2. Now remove the battery
3. Repeat step one above
4. Let the laptop sit for 10 minutes.
5. Reinstall the battery
6. Make sure docking station is unplugged, and insert laptop into docking station.
7. Plug in power supply (to dock)
8. Start the laptop.
9. IF IT STARTS, let it run a while to see if the battery is charging
10. Remove it from the dock and repeat steps 1-5 above and then go directly to 8 (start without connecting dock).

CONCLUSIONS: If the laptop started in the dock on step 9 but not 10 (only on battery), your battery or power regulator circuit may be damaged. However, if it starts in step 10 but not step 9, your docking station -or its AC power supply may be damaged Let me know how this comes out, please.

Randomly shutting down


Hi katrina1331, From what you describe it could be a couple of things but the two the come to mind first are power and perhaps overheating. The fact that you can?t run on battery power very long would suggest it can?t hold a charge or much of one or the AC power adaptor or charging circuitry aren't working correctly. To proceed I need to get some more information from you: Are the A/C adaptor and the battery the original ones and how old is the laptop? There are several LEDs on your laptop, (we?re going to ignore the touchpad light and the wireless LED), a power/standby LED to the top left of the keyboard three just below the touchpad. The left LED is another power/standby LED, the hard drive LED in the center and the battery LED on the right. -What are they doing just before the shutdown and immediately after while running on A/C power? -What are they doing just before the shutdown and immediately after while running on battery power? Try running the laptop with the battery removed and the A/C adaptor plugged in. Do you notice any change in running time? With the battery and A/C power plugged in click on Start, Settings and then Control Panel. Find and double left click on power options. A box labeled Power Options Properties will open, click on the tab labeled Power Meter. It should indicate the battery is at 100% or that the battery is at some percentage and that it is charging and running off A/C power. Let us know what you find. When you first start up the computer run your hand along the bottom of the laptop, especially along the four screened vent areas, to roughly gauge the laptops temperature. Use the laptop in a way that causes it to turn off and then run your hand along the bottom surface again. If the laptop is hot, to the point where it is uncomfortable to touch, then overheating may be a factor. Let us know what you find out and we?ll continue.
