My g570 laptop is 4 years old, so probably time for a new one...BUT I'd like to get some more life out of this if I could.
Currently I'm running only on battery power. The power button (upper left right above the F1 key) is solid white however when I plug it in...it'll start charging for about 10 seconds and then it stops charging and the power button starts flashing white.
I've tried the shutting down, taking out the battery and pressing the power button and also holding the button to discharge. Still the same outcome.
I've also tried turning it on with the battery removed and just the AC power source and it turns out and makes it past the Lenovo splash screen but loses power before getting to the windows loading screen.
Any other suggestions? Or should I just assume the charging circuit on the motherboard has failed and I should rescue my data while I can?

Hi jcokl ,
Remove the harddrive and the battery and have it run on just ac .
Turn it on using the Novo button (item 4 page 69) to access the BIOS.
Would the laptop shut down too or would you be able to stay in the BIOS screen ?
Take the time to back up your files from the harddrive maybe using an external harddrive enclosure.
Update us how it goes.

Hi jcokl ,
Recommended power checkout (page 21) steps for this issue that you can try.
Checking integrity of the ac adapter (specially if you have another charger or test the original on another laptop) can be tried first as it may be an issue with the DC port and cable or the systemboard itself .
Further investigating the cables (loose or shorted) and fan / thermal paste / air vents during cleaning the internal system may help isolate the point of failure.
Service centers would be able to verify the issue as they would have the tools to check as other hardware parts may still be ok.

Hi jcokl ,
So this leaves us with the systemboard and dc in port and cables.
As it still shows the Lenovo logo initially , possibility of completing power on self test but as it goes further cannot maintain it or that it choose to turn off itself to protect the CPU .
Would it stay flashing white (sleep mode / status indicator page 29) on the power LED without the harddrive and battery or completely off ?
You may review the system manual for reference if you have the tools to check for burnt/hot areas / cables or fan system for cleanup. If you don't have the time or rather have a service center check on it , backup your files as needed.

Thanks for your help. I don't feel that it is worthwhile to continue to try and diagnose the problem. The laptop is 4 years old, so I think I'll just seek out an adequate replacement. Thanks again.

Hi jcokl ,
As this may require a systemboard replacement , cost of both parts and labor may be more than half the price getting a new system.
I would not encourage you to just throw out the model as a lot of the other parts like LCD panel , RAM , harddrive , chassis cover would still have a favorable price if you resell it by piece or as a whole or even a backup spare part for your wife's laptop.
