First of all, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

DC Jack diagnosis:
1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.

First replace it with another working charger, see if the problem gone. If not, there may be strong possibility that the power jack was broken.

Here below are some common symptoms of a bad charger.
-The laptop only runs when you keep the power cord in a certain direction.
- The laptop only runs on battery power.
- The laptop will not charge the battery.
- The laptop switches from AC power to battery power intermittently.
- The unit suddenly shuts off
- Sparks come out of the back of the laptop.

Looks like you have a faulty battery, since you bought your laptop 4 months ago, I think it is still covered by their warranty. Please try to contact the manufacturer about the possible battery replacement. :)
Some of the things to do/check if the manufacturer requires you to return your laptop to them: 1. Backup all your important files to a different media/storage, like an external hard drive or burn them to blank DVD's
2. You can also tell them that it MIGHT be your charger that's faulty. Either way, they SHOULD check the battery and charger.

Do a hard reset by turning off the computer and removing the battery and unplug the AC adapter. Without any power source, press and hold the power button and put everything back after. Power on the computer again, if it does not work, try to connect your laptop to an external monitor. If it shows some display it means that the LCD monitor of your laptop has gone faulty.

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.

Laptop pwrs on but no display on screen or external monitor


Are you sure your battery didn't die. Try this, take out your battery, plug in the AC adapter and power on the system. If still nothing, maybe the AC adapter has gone bad.
