Cannot turn on

If it is orange or is blinking orange, the battery charge is low or expended. Remove the battery and re-install it. Plug in the AC adapter and connect it to an outlet. Turn on the computer.

When the battery status light blinks green and orange, the battery temperature is too hot for charging. Shut down the laptop, detach the AC adapter, and allow the laptop and battery to return to room temperature before attempting to charge the battery.

If the battery status light blinks orange rapidly, the battery itself may be defective.

Hi m529,

I see you are having issues with you G550 charging.

You mentioned that the light on the charger is lit up but then it suddenly switches Off, and you also mentioned that the charge still has a light but the power is somewhat low despite of a fully lit up charger Light.

Have you tried draining the power from the system?

• Remove the battery and the Charger or AC Adapter as well call it from the G550 then press and hold down the power button for 10-15 seconds to drain power from the system motherboard.
• Once drained connect the AC adapter but do not connect the battery yet, then turn the Laptop ON to see if the system will power ON using the AC adapter/Charger if it powers up then there is no problem with the AC adapter/charger.
• After testing the AC adapter if it is working power down the Laptop doing a normal shut down.
• Once shut down or turned Off insert the Battery back in the Laptop then turn the Laptop ON using the battery only without the AC adapter/charger see if the system will turn ON using the Battery only.
• If the Laptop powers On using the battery alone with out the AC adapter then the battery is most likely working as well on the issue.
• Now power down the Laptop then connect the AC adapter to the Laptop with the Battery in the Laptop as well then turn the system ON again see if the problem will Occur again having the battery and the AC adapter/charger if the Problem happens with both Battery and AC adapter on the Laptop then the problem is the Motherboard, most probably the motherboard is having issues relaying power from the AC adapter to the battery and may be sent to the Depot for repairs.
  

I suggest that you call Lenovo for further information about your system, if you still have warranty and is still in the one year period then your system will be covered for any repairs needed - you can call @ 1 877 453 6686 for troubleshooting, you will be asked for a serial number Located underneath the Laptop on a small white sticker that states s/n meaning serial number.

I hope that this Helps.

Have a nice day,

Hi,
Welcome to FixYa!

Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.


1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.


Hope this will help...Thank you for using Fixya...

This is only the first of many things you may need to do to determine the fault. But it is a process for determining the exact cause.

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a 'power reset' of the notebook.

1. Unplug the ac adapter. Keep ac adapter unplugged.
2. Remove the battery and keep the battery unplugged.
3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
5. Normally power on the notebook.
6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
   If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.

The diagnostic procedures from the Dell User Guide are as follows:

Total Power Failure When Using a Battery
If an AC adapter is not connected to your computer, the computer's power source
is a battery. If the battery indicator flashes amber or is a steady amber, the
battery needs to be charged. If the battery is flashing green and amber, the
battery may be defective. To troubleshoot this problem, use the following
procedure.
1. Turn off the computer and peripherals, and disconnect them from AC power.
2. Reseat each installed battery by removing it and then replacing it.
3. Turn on the computer. Does the green power indicator light up?
Allow one minute for the computer to initialize its components before checking
for signs of power.
Yes. Continue to step 4.
No. Use the AC adapter to connect your computer to AC power. If the computer
operates normally when using AC power, go to step 7. If the computer does not
boot when using the AC adapter, see the previous subsection, "Total Power
Failure When Using the AC Adapter."
4. Does the battery indicator flash amber or show a a steady amber light?
Yes. The battery needs to be charged. Go step 5.
No. Go to step 7.
5. Connect the computer to AC power, and fully charge the battery.
For instructions, see the topic titled "Charging the Battery" in the online
System User's Guide.
6. As the battery charges, does the green battery indicator light up?
Yes. Go to step 9.
No. Go to step 7.
7. Is the battery indicator flashing green and amber?
Yes. Your computer may be in a hot environment. Charging the battery in this
condition may affect the life span of the battery. Continue to step 8.
No. The problem is resolved.
8. Disconnect the computer from AC power. Is the the battery indicator still
flashing amber?
Yes. You may have a defective battery. Continue to step 9.
No. The problem is resolved.
9. Remove the battery, and press its test button. Is the uppermost indicator in
the charge gauge of the battery flashing?
Yes. You have a defective battery. Continue to step 9.
No. The problem is resolved.
10. If a spare battery is available, fully charge it, and then install it in the
computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective. Call Dell for a replacement. (See
Chapter 5, "Getting Help," for
instructions.)
No. Call Dell for technical assistance. (See Chapter 5, "Getting Help," for
instructions.)

The AA1 has a built-in BIOS recovery routine, which makes it possible to flash the BIOS even if it doesn't POST and the system doesn't boot anymore. It's meant for emergencies and is also known as crisis disk mode. Use at your own risk.

First format an USB flash drive with FAT.

Download the latest BIOS, and extract all files from the zip file. Put both FLASHIT.EXE and the BIOS file with FD suffix in the root directory of the drive. The files must not be in a folder. Rename the BIOS file toZG5IA32.FD, that's important.

Turn the AA1 off, with the USB drive still connected, and make sure both battery and AC adapter are also connected.

Press Fn+Esc, keep it pressed and press the power button. Release Fn+Esc after a few seconds. The power button starts blinking at this point. Press the power button once. The AA1 will now initiate flashing the BIOS, do not interrupt it under any circumstances. After a while the power button stops blinking, and the AA1 reboots shortly after. Wait patiently.

The BIOS has been re-flashed and all settings are reset to default.

If the AA1 doesn't reboot by itself, but the power button still blinks, wait a few minutes before turning it off, and try again.

Hook up only the ac adapter to the DS to see if it turns on. If it does then we know the ac adapter works. We know the battery got fully charged but the system isn't turning on with the battery that is fully charged up.

I would say your battery is defective but you won't really know until you fully charge up a known good working battery and test it out.

First follow procedure to try to reset the power.

1. Unplug the ac adapter. Keep ac adapter unplugged.
2. Remove the battery and keep the battery unplugged.
3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
5. Normally power on the notebook.
6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
   If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.

From Toshiba, try step-charging the battery or Battery conditioning procedures:

Batteries don't last forever. All types of batteries gradually lose their ability to hold an electrical charge as they age. Eventually, the computer's battery charge indicator may show that the battery contains less than a full charge, even though the battery has just been fully charged. The computer will then not run for as long a time from the battery as when the battery was brand new.
You may prefer to simply replace the battery if this happens, but you may also wish to try 'step-charging' the existing battery per the following instructions.
This procedure should work for the battery in any Toshiba notebook. Follow it only when you find that the computer will run from the battery for just a short while.
Check the User's Guide for more specific information about charging the battery in your computer .

Procedure

Step-charging the computer's battery

1. Unplug the AC adapter from the computer, and turn ithe computer on. Let the computer run from battery power until the computer turns off, indicating that the battery is fully discharged. Time this interval, but not with a software clock running on the same computer.
   
   
2. Remove the battery pack from the computer.
   
   
3. Unplug the AC adapter from the computer.
   
   
4. Wait at least 30 seconds. The first time through this procedure, use a soft cloth to wipe the battery pack's contacts and the AC adapter's plug.
   
   
5. Re-insert the battery pack.
   
   
6. Plug into the AC adapter into the computer again and check the fit of its plug in the wall outlet, making sure the connection is secure.
   
   
7. With the computer turned off, let the battery charge until the battery status light or icon glows green, or otherwise indicates a full charge.
   
   
8. Unplug the AC adapter from the computer.
   
   
9. Remove the battery.
   
   
10. Wait at least 30 seconds, then re-insert the battery.
    
    
11. Plug the AC adapter back into the computer.
    
    
12. Let the battery charge again until the battery status light turns green or otherwise indicates a full charge, again.

Repeat this procedure, starting from step 1, at least three times. Each time, check to see if the computer runs longer from its battery than the previous time.

Battery Conditioning:
IMPORTANT!! Interruptions in the charging cycle can be responsible for an issue called "memory effect" which may reduce the battery's charging capacity. Whenever you suspect the battery performance is not at it's optimum you should try using the following "Battery Conditioning" procedure.

Before you start: Turn off your battery saving features temporarily.

***IMPORTANT*** Repeat the following steps 2-3 times!

1. Unplug the power cord from the computer
2. Turn the computer on and let it run until it shuts itself off.
   Note: Using the CD-ROM to play an Audio CD will speed the discharge.
3. Plug in the power cord (While the system is off) charge the battery until the battery light changes from flashing green to solid green
4. Remove the battery for 30 seconds and then replace it.
   Note: If the battery light isn't lit, wait a few moments, if it still does not light check your power connections.
5. Continue charging the battery until the battery light turns solid green once again.
   **REPEAT THIS PROCEDURE 3 TIMES**
