I have lenovo 3000 N200 laptop. I left the laptop in the hibernation and the power was on. After a while i came back and the laptop was not starting at all. It won't work on the AC or battery and no indication of power supply. Please help.
Looks like you have a Vista machine. It may not have been mentioned here yet or maybe it has, but hibernation in Vista is pretty dicey and worse than dicey on some laptops. Some of the recent patches may have addressed this, but so far I have been disabling it on all my Vista repair jobs. For your PC the first thing you want to address is the hiberfil.sys file located in the root directory of your hard drive. This is done by removing your hard drive from the laptop, connecting it to a usb to sata/ide dongle which can be found at geeks dot com for pretty cheap and plugging it into your desktop PC (assuming you have one of course). Your drive should appear in My Computer as an extra drive, or a usb mass storage device in safely add or remove hardware located to the lower right on your taskbar. Before deleting hiberfil.sys, do a quick scandisk. I also delete the paging file/pagefile.sys just in case a Virus is the root cause. Deleting these will not stop you from booting and both are safe to remove. After you have completed these steps, reinsert your Drive into the laptop and try to boot. If all is well you should be able to boot into windows, but remember that now your hard drive is flagged as dirty by windows due to an improper shutdown. Do a proper shutdown and reboot, optionally you can have windows test the drive on reboot. If all went well you now know your problem is the hibernation mode specific to your OS (Operating System). In XP you can turn this off easily by opening your power schemes located in Control Panel, but in Vista there is a different approach. Navigate to start/programs/accessories then command prompt, then right click command prompt and choose, Run As Administrator. Then type this in the dos box powercfg /hibernate off. This will turn off hibernate until you have the proper patches installed for your Lenovo. Also remember to check the IBM/Lenovo site for problems like yours in the Q&A section and trouble shooting. Should none of the above solve your problem, I would suggest running a copy of either DSL linux or Puppy linux and doing a few hardware tests. Download either of these and choose the Live CD download, make your bootable CD and away you go. If however your Laptop does nothing at all, try removing the Hard Drive and rebooting with no drive installed. If your lockup is gone then you can likely blame the hard drive.
Hi, thanks for you reply. But I have tried it all. But I think you might be able to help me with this. I have tried removing each and every part of the laptop and still my laptop does not start at all. It does not show me any indication of power supply in the laptop. Now I have checked the hardware and I am not sure about this but my AC adopter shows me full 20.3 V as output voltage. when it goes to the power on switch it goes down to 15V and then as soon as I press the power on switch it goes down to 2 to 1v. Also at the battery end when I checked the voltage it gives me output of 1 to .02V. I have my doubts on AC adopter. But not sure if to blame the adopter or motherboard. Thanks for your help.
