Question about Lenovo G470 Core I5 4gb 500gb Hdd Laptop Blu-ray
First, the problem is with thingy where you plug in the charger (in the laptop) the circle thingy at the right side. so fixed it. but then after fixing it, we cant turn on the laptop. so we charged it but still we cant open it. what are we going to do now?
Hello.The most common reasons for power issues are the battery, power jack and power adapter/cord.Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.If no change, the laptop charger is probably faulty and needs replacement.Hope this helps.

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.

If you do not have either a manufacturer warranty or extended warranty from the retailer use it now. Contact them. Avoid telling them that you dropped the computer...you will void a manufacturer warranty. If you don't have either option then you can continue portability with an external laptop battery. They tend to be heavy, but they tend to provide 5 or more hours of portable use. The extended battery plugs into the same socket as your regular external power supply. I have included some links for product options.

Most likely its the DC Power Jack. Happened to me. You can find the part online by searching for "450ROG DC Jack" and then just resolder yourself or take it to a repair shop.

If the charger is older and since you saw the light go on then off again, it could just be the charger wires. Assuming your charger has a black box attached to it, try pushing the cord in towards the black box (usually the end leading to your laptop) . If that doesn't work, wiggle the cord in that area. If this works, your problem is simply the wire is worn out. You can fix it by exposing the inside wire where the bad connection is, snip it, reconnect and cover with electrical tape. I just did this to my sister's last week.
