There is either a short circuit in your laptop, (Diode protection due to wrong polarity used) or the power supply is faulty.

SOURCE: When power cable unplugs computer immediately shuts down (have replaced battery)

Sounds as if the power pin (inside the computer) is damaged. The part is under $ 10 but the labor is gonna be a hundred to two hundred bucks. You can, if you are careful, fix it yourself.

You can also get a JerkStopper cable retention device to hold the cable in the correct position until you get the pin fixed. The cable retention device is designed to keep you from damaging the pin by pulling on the power cord. In this case, it sounds like it's too late for that.

SOURCE: year old advent netbook 4211b will not turn on,

When you press power button press F1 or F2 or "del" key if you can see bios screen then you not need to refix RAM memory or reset bios.
IF you can see bios screen then lake sure harddisk is detected and SATA is disable then save settings and exit.
Also when you power up press F8 key if you able to see safe mode and other menu then you have change screen resolution enter in enable vga mode.
Then open control panel and display then change scree resolution to 1024*768.
Then apply and ok.
But if you can't see bios screen or nothing in dispaly then you have to refix RAM memory .
Check in back side there is 1 plate open it then refix RAM memory.
If still not get display then open back cover of laptop then find motherbord on it then pull cmos cell for 10 minutes so all settings go to defaults then again refix cmos cell then check.

Let me know if you need more assistance.
Thanks.

SOURCE: Lenovo Laptop not starting and Charger's light blinking..

It sounds like your power cord is bad. If you got a notification that the battery was getting low and you had the power cord in, that means the power cord was not charging the battery, you were working off the batery even though the power cord was plugged in and eventually you drained the battery.

You'll need to purchase a AC Adapter Power Cord that is built for your laptop, not a one size fits all laptops that the big box stores will sell you . By one size fits all I mean the end that goes into the computer is removable and you can replace it with one of many ends that come with it until you find one that fits. Use it and you'll surely burn *********** board out eventually.

Lenovo z570 not powering on


Measure the voltage at the AC Adapter plug, and see if it is within 5-10% of the rated voltage. If the voltage is not correct, then the battery will most likely not be charging, and the system will drain the battery and die in the middle of what it was doing...booting in your case.

You can tell how much voltage is remaining in your battery and if it is charging by checking the blinking of the battery status light.
Download the Hardware Maintenance Manual here:
http://download.lenovo.com/UserFiles/UserGuide/en/User%27s%20guides%20and%20manuals/Z370&Z470&Z570/Lenovo%20Z370Z470Z570%20Hardware%20Maintenance%20Manual%20V1.0.pdf
and go to page 30 and look at item 7 under battery status for blinking light meaning.
1. Blinking amber: (500ms off/1s on)
The remaining power of the battery is less than 5% of
its capacity.
2. Blinking amber: (100ms off/3.2s on)
The battery is being charged with the remaining
power between 5% and 20% of its capacity.
3. Amber: The computer is operating on battery power with the
remaining power between 5% and 20% of its
capacity


With the AC Adapter plugged in, and giving the correct voltage, If you are getting 1. Blinking Amber (light on for 1 sec, off for 1/2 second), then the battery is not being charged. Could be AC Adapter, Battery or Battery Circuit on motherboard. If the light is solid on 3. Amber, then the battery is not charging, and is draining.

Also make sure the power socket on the laptop is not loose or damaged. If it is, then it will need to be replaced.

I hope this gets you in the right direction.

Lenovo Z570 powers on but screen is black


if you have an external monitor or a smart TV you can hook it up to that to see if it even works. If it works then you look real close to the screen of the laptop without it being hooked up to the external screens and see if there is a faint image on the screen or you can do this part first. If there is an image but still dark check to see if the brightness is turned down. On the keyboard you will see a sun and moon shape on the F keys just press the FN key with the key for the brightness for a few seconds if it doesn't come up you may need a new screen or power board for the laptop.

Power cord light is yellow not green


Hello,Yellow means your battery charge is low, and it is being charged.


Green means you have a full battery charge.


So probably it seems your battery is out of juice. Keep it on charges & it should be fine.

If there is nothing changed, you may need to exchange the laptop charger.

Lenovo Ideapad Z570: Battery indicator shows the Power is plugged in & charging. But the Battery charge percentage doesn't increase. How to fix this?


The battery might be nearing the end of it's useful life and needs to be replaced. The battery only lasts for so long then it has to be replaced.

Buy a battery on ebay base on your computer's Make and model, not the model of the battery.

Thinkpad not turning on, Flashing Amber light when battery inserted


The problem is most likely in the DC jack in the laptop, "common issue" the laptop must be dismantled down to the motherboard level, chances are the main board must be removed from the bottom chassis and flipped over to expose the solder joints underneath the DC jack and a resolder touch up done.

First of all check your VGA cable is working or not.

If VGA cable is ok than do the following steps.
  1. Turn off all peripheral devices connected to the computer.
  2. Disconnect the computer's power cord from the AC power source (wall outlet or power adapter).
  3. Remove the computer cover.
  4. Locate the battery on the board (see figure below).
  5. With a medium flat-bladed screwdriver, gently pry the battery free from its connector. Note the orientation of the "+" and "-" on the battery.
  6. Wait for 1 to 5min then re-place the battery back again.
  7. Re-place the computer cover.
  8. Plug the computer and all devices back in.

Second step you can do is
1) Remove the RAM from the RAM bank clean it properly and insert it back again.

If still you are facing the same problem ... you can Remove the CPU fan and put some cooling paste on top of CPU and re-place the FAN back.
