My Lenovo 3000-N500(Type 4233-79G) (1.5 Yrs Old) will not boot from Battery or Power Adaptor. Both power sources are OK & when both power sources plugged on to this machine, this laptop displays Battery Charging Light only with ACtoDC power adaptor connected to this machine and during this time or any time this machine cannot be turned on at all and so it will not go through booting sequence in 1st place!!!!!!! [Notes: This laptop has Win-Vista-Home-Premium-SP2 -32Bit preinstalled. This machine started displaying horizontal line flashes across it's display-screen at intermittantly which got to the maximum within a total period of two weeks. This effect was shown during boots ups & at normal running of the machine. At boot-ups I had to press enter button to get to the window's password-login-screen. But before the login the screen it was wildly going flashing across the whole screen horizontaly. So I took apart this machine to check CMOS(BIOS) Clock Battery of 3Volts onboard voltage which showed zero volts so I unsoldered this rechargeble 3V Battery & checked it's voltage with DMM & it read 3.135V. Hmmmm - so it seems the Battery is OK(MotherBoard is Hannstar JIWA-3LA-4212P-Rev:2.0). I have re-assembled the whole machine back as should be with CMOS original Battery in soldered position and retried booting to get this made in china machine back into the life from total death but got no success in getting it booted]. I wonder whether it has built in chronic in health problem/s or else. I would be most obliged if you could show me remedial action/s to this totaly dead lenovo notebook laptop.

Re: My Lenovo-3000-N500 has gone totaly dead and cannot...
Clearly it's a hardware issue if your laptop is still in warranty call lenovo thinkline @ 18004267378 because it might be a possible DC-IN port or motherboard problem..Request for service repair.

Do any lights come on when you press the power button? If not, did you get all the cables reconnected properly? If lights come on or fans come on when you press the power button, then it sounds like the screen has gone bad. That is the symptoms you are describing.
I do. Open the Lenovo 3000 N500 Notebook PC, and un-stick it.
You need the Service Manual. Lenovo calls it an HMM. Hardware Maintenance Manual
Below is the Lenovo Support link for the download page, for the Lenovo 3000 N500's Hardware Maintenance Manual. The Top file listed is the one you want.
Either the site is updating right now, or Lenovo no longer offers this manual. Clicking on the file does no good.
retry to disconnect the cable and the battery then Press & hold the power button . Replug cables and battery, turn on pc. If symptom persist, consult technical support at 1-800-426-7378
Turn on your computer. Press F2, while the initial screen is displayed. The BIOS Setup Utility screen opens.
Boot priority order look for your had disk here. order should be 1. cd rom then 2. hard disk then 3. usb or network boot device. anything bellow doesn't really matter much.
The light that stays on is probably a power indicator. Remove AC adapter and battery. Hold power button down for 20 seconds. Put battery back in and reconnect AC adapter. Try to start your computer.
I had the same problem. There is a touchpad on the laptop, just above the Pause button, which turns the pad on and off. It is situated on the far right hand side (there are also touch buttons for the volume controls there), between the N500 logo and where the power supply jack fits in.
For fdisk utility Boot from xp bootable cd,Go to the repair option.In this section you have to mention username & password.Then start Fdisk /f utility.
