Question about Lenovo G470 Notebook I3-2310m Dual Core 2.1ghz 4gb 500gb Win7hp-64bit 432825u

1 Answer

The previous day that I charged my lenovo G470 laptop by connecting the charger tip and the AC power adapter jack, it is working very fine. The tip attaches itself in a stable manner. However, when I tried to connect the AC power charger tip to the AC power adapter jack, the tip is not held perfectly anymore making it not attaching the two connection. With this I cannot charge my laptop anymore. What do I need to do to fix this problem.

You need to install a new jack to firmly hold the power adapter plug.

My laptop is not charging. i plug the power in but still doenst charge. im not sure if its on the power cords or on the laptop please help asap i need my laptop for school :(


Does the laptop work on AC ? Is the battery or cord/charged a replacement? First, try another cord/charger of the EXACT same specs as original. Second, Is the battery good? How old? Over 4 years? Have it tested. Beware of inexpensive aftermarket batteries and cord/chargers. I assume the laptop works on AC? If you unplug the AC , with battery in, the laptop shuts down immediately?

Laptop is charging but cant turn on


When you say "you fixed the thingy" (ac jack), how did you fix said "thingy", did you open the laptop and replace the damaged/broken "thingy"? Need more info. Perhaps the "thingy" isn't fixed? Try remove any DVD,CD, USBs from the laptop, removing the "thingy" , remove the battery, Hold down the on/off button for 10 seconds, replace the battery, replace the "thingy" push the on/off button. That said, When you fixed the "thingy" was ALL power removed from the laptop AC plug, Battery, If not a short may have occurered.

DV4 won't charge


Maybe it's the charger or dc jack that was broken. Just test with a known working adapter connected, see if it charges, if yes, then your charger is broken, while if not, then you have to resoldered your dc power jack.

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,

The battery cannot charge after connecting to a power source


Take out of your battery, then plug in your ac adapter, see if it works, if no, then you have a faulty ac adapter, you need to replace it; and if yes, then you adapter is ok, the battery or dc jack may be broken.

Is the AC Power adapter the original adapter of the laptop? If it is, try to drain the battery and charge it for 8-12 hours without using or opening the laptop just charge it. After charging, remove the power adapter as you open your laptop. Make this way a habbit of using and charging your laptop to make the charging and battery life last long.

I would plug it in without the battery first and if the laptop stays powered on your adapter probably is fine and you have an issue with your motherboard or battery. If it still does not work replace the power adapter they are cheap and its technology sometimes it just breaks! hope this helps!!

Hi smialkovskyi,

With this specific concern that you do have, unable to turn on your Lenovo Z560, there 3 components that need to be checked. Your battery, the AC adapter (charger) and as well as the DC In port.

1.Based on what you have said, with the battery alone you have noticed that it's led indicator will show however still can't turn on system. Battery seems to be in good condition however no enough charge to turn on the system.

2. For your AC adapter, when you're using it without the battery nothing happens. To check if this is defective try using another AC adapter that is compatible to your unit. If your computer turned on using another AC adapter then your charger needs replacement. (You may also try using your charger to other unit where it is compatible, just to test).

3. However, if after doing the previous instruction and still system won't turn on then it could be the DC In port which is defective. This port is built in to *********** board.

After doing all these you need to contact Lenovo. They might be replacing your charger or *********** board if system is under warranty.

Hope this helps.

Thank you for using Fixya.
