When you plug in the adapter into the laptop a LED lights up to indicate that it is connected to the mains supply and is charging.
A faulty adapter or the connector is not making proper electrical contact, this causes the LED not to illuminate. Wriggle the connector plug to see if the charge light comes on, if it does then the loose connector needs repairing.

Check the adapter with a multi-meter, the voltage reading should be a slightly higher than the voltage that is printed on the label on the adapter. If the voltage is more than 10% below the nominated voltage then replace the adapter it is faulty.

SOURCE: Lenovo R61 Dead

The power supply in most computers has a fuse, either internal or external, that can blow without you noticing. Basically, you've been on battery operation this whole time, and the battery's finally gone dead.
It will be necessary to open the case and examine the power supply section. It may be possible to replace the fuse yourself, but any operation of this nature that involves opening the case will void any warranty you may have.

I have a Dell C400. All of a sudden it won't boot. Can't even access BIOS. Display has nothing. Battery light keeps flashing from green to amber.


Remove the battery and the hard drive , use the charger and try to boot to BIOS. If it fails then the laptop is dead.

Try reseating memory modules.

Try taking out all parts like Hard drive, memory, wireless card. Does it do anything? IF it beeps, then put the memeory back in and try again.

Reseat all of them. Then try. Then if you have two memory sticks try one at a time in different slots. If nothing changes.. probably a bad motherboard or processor. (motherboard is more likely)

I have IBM LAPTOP thinkpad T43 SERIES. it was working tiil yesteraday. Suddenly it turns switch off. I thought its the problem with AC adapter. I bought a new one. It shows it turn it on but its switch...


It's not necessarily hardware related, can you boot into Bios? If you can try to boot info safe mode, that's F8 for most PCs. I would suspect something with your motherboard drivers, then again it could just be your battery. Not all laptops will operate with the battery out, there is some kind of failsafe to prevent overheating in some, because without a battery the power supply can be fried sometimes.

Hope this helps

My mobile is dead


I just had this happen to me yesterday. I fought with my phone for about 3 hours removing the battery and trying to restart it. It would take about 5 minutes for it to finally boot and once it did the touch screen would not work. So I did a hard boot and within 5 minutes my phone was back to normal. I lost all my contacts but I just did a restore with the backup software. To do a hard boot hold down the red and green buttons on the front of the phone and push the reset button on the bottom of the phone with the stylus. The reset button is on the right side of the power/usb plug. As I said my phone was back to normal in just a few minutes.
