Boot up problem

If you can reach inside the computer and rub the battery contacts gently to remove the corrosion ,which is invisible , this will help greatly. Sometimes even a new battery will suffer the same. Clean the battery contacts also turn off the laptop and charge it fully do this on a regular basis. Say once every 2 months

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,

Good morning, afternoon, evening or night; whatever time you are viewing this solution post. Thank you for choosing FixYa to solve your problem. So you have connected your Nanomax iPod to the computer and it's not charging like it's supposed to, and you want to know how you should charge it properly? There are two ways you can charge the battery - charging via your Dock Connector to USB Cable, or the Apple USB Power Adapter (which is sold separately). Here are the step by step instructions to charging your and Nanomax.

Using the Dock Connector to USB Cable

1. Using your Dock Connector to USB Cable, plug the dock connector end to your iPod and plug the USB end to your computer. Make sure the computer you are using has a USB 2.0 port (check your computer's technical specifications to see if it's USB 2.0 certified). Most USB ports on the keyboards of laptops do not provide enough power to perform charging activities. If you have a Docking Station, plug the docking connector into the station and placed the iPod in the station as well.
2. Make sure your computer is fully awake and not asleep (meaning in sleep mode).
3. A fully charged battery takes 3 hours to complete. An 80% charged battery takes an hour and 30 minutes. The battery is charging when it shows the charging icon (a battery not fully shaded in green, with a lightning bolt).The battery is done charging when the "fully charged" icon shows (a green-shaded battery with a 2-prong plug showing).
4. When you are done, disconnect the cable from your computer.

Using the Apple USB Power Adapter

1. Connect the Alternating Current (AC) Plug Adapter with the power adapter (if connected already, skip this step).
2. Using your Dock Connector to USB Cable, connect the dock connector end to your iPod and the USB end to the power adapter.
3. Plug the power adapter into a polarized wall outlet or surge protector outlet.

I think you connected everything correctly, but the USB port on your computer did not have enough power to charge your battery. If that's the case, you will have to find a computer that has a USB 2.0 port on it (like a desktop PC or MAC, or a car adapter charging device) and connect to it, or use the USB Power Adapter (sold seperately). I think this pretty much answers your question. I hope this benefits you the best way possible. Once again, thank you for choosing Fixya as your one-stop solution spot for your problems. Have a good day, evening or night; whatever time you are viewing this, and visit us again the next you need assistance troubleshooting.

If a PC suddenly fails to boot properly, you should perform a hard reset as the first action. Performing the hard reset will correct many problems. If the computer still does not start properly, select your symptom from the list below to guide you to the recommended corrective actions.

1. Disconnect all peripheral devices and remove all USB devices and SD media cards. You want to test the computer not the accessories!
2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
3. Reconnect the AC power adapter (but do not insert the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a fan or other moving parts turning.
4. If the computer does not start, the LED lights do not glow, and the display is black, you can perform one or more of the following actions to resolve the no power issue.
   • Verify the computer is receiving power from the AC adapter . Verify that the AC adapter is not damaged and is connected correctly to a working wall outlet plug. Verify AC power is connected to the system board by examining the AC adapter, wiring, and pin connection for damage. The keyboard LEDs will glow when AC power is connected to the system board. Damaged components, like the AC adapter or the pin in the power connector, may require an HP-certified repair.
   • Use a different AC power adapter . If you have access to a different AC adapter or power pack that is designed for the computer, connect it to the notebook and try to start the computer. If you own or have access to more than one notebook, verify that you are using the adapter which belongs to the notebook. CAUTION: Using a power adapter that does not meet the power requirements or has the wrong type of connector may damage the computer. On newer notebook models, connecting the wrong adapter to the notebook may cause the power LED lights to blink but not power the computer.
   • Remove the battery and boot on AC power only . A discharged or defective battery may prevent the AC adapter from supplying enough power to start the computer. To verify that power from the AC adapter is available for PC; remove the battery, connect AC power adapter, and press power button. If available, try using a different AC adapter, that is rated for the PC, and repeat this test.
     • If LEDS do not glow and the fan or hard drive do not spin, AC adapter may need to be replaced.
     • If LEDs glow and PC boots, the battery may need to be replaced.
     • If LEDs glow but PC does not boot, go to LEDs glow, fan is heard, but display is black or blank section.
   • Remove the AC adapter and boot on battery power only . A defective AC adapter may not charge the battery and prevent the computer from booting on battery power only. To verify battery power available for the PC; connect AC power adapter, allow battery to charge for 30 minutes or more, disconnect the power adapter and press power button. If available, try using a fully charged battery, of the same type, from another computer and repeat this test.
     • If LEDS do not glow and the fan or hard drive do not spin, battery may need to be replaced.
     • If tests of both the battery and the AC adapter fail, there may be a problem with system board requiring service by HP.
     • If LEDs glow and PC boots, the AC adapter may need to be replaced.
     • If LEDs glow, but PC does not boot go to LEDs glow, fan is heard, but display is black or blank section.

Startup problems
If the notebook doesn’t respond when you turn it on
• Connect the AC adapter.
• Reset the notebook by inserting the tip of a paper clip into the reset button on the
bottom of the notebook. Then press the power button to turn it on.
• If the notebook still doesn’t respond, remove the battery and AC adapter, remove
any PC cards, and undock the notebook if docked. Then plug in the AC adapter
again, and reset the notebook using the reset button.
If the notebook won’t boot from battery power
• Make sure the battery is properly inserted and fully charged. Check the battery
charge by removing it and pressing the pad on the side of the battery. The lights
show the charge level.
• If available, try another battery.
If the notebook won’t boot from the floppy disk drive
• Make sure the floppy disk drive is selected as the boot device.
• If you’re using a USB floppy drive, use the BIOS Setup utility to make sure
Legacy USB Support is enabled. If your notebook also has a built-in floppy
drive, use the BIOS Setup utility Boot menu to make sure the USB floppy drive
is the first device under Removable Drive.
If the notebook stops responding after booting
Check whether you are connected to a TCP/IP network with no DHCP server. This
can cause a long delay at startup because DHCP is enabled. Contact your network
administrator to determine the proper TCP/IP configuration

***IF THE NOTEBOOK HAS POWER BUT WONT BOOT INTO OPERATING SYSTEM-
Press F2 when you start it to enter BIOS to check your BOOT ORDER to make sure your HD is listed first on the list.
If it is not listed remove it and reinsert it and then try again.. GREAT LUCK!! Please Rate Me, K? Thanks- Lucky4lynn2

Jim just cheek  if your AC adapter is HP Compaq nc4200 compliant if thats OK your power pack should have a problem . cheers Jim

Full charge the battery first so that it can contain enough power to boot your laptop. Because it is a new battery it should fully charged for the first use.

Hi there.
Sounds like the battery could be faulty.
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.

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**
