Not booting up....seeing the power and battery led.

• rjsymmes has the most accurate solution. Start with a battery replacement. Next course of action is to use a Bootable Media Source (Windows Disk or Recovery Disk) to see if the laptop responds and can have the Start Up repaired. If a Boot Media fails, then examine RAM, Hard Drive removal, then boot. Last resort Motherboard.

If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.

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.

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.

try pulling the hard drive loose and see if it tries to boot and comes up with no boot device found if it does the hard drive is bad if not the bios is corrupted and will need the bios reflashed.

Hello,

Even though a lot of things might have gone wrong and caused this, especially if where you place the laptop is not well ventilated, and the CPU becomes very
hot.

It then shuts down automatically...and you will have to wait for a few moments, get a cool environment and power it on.

But I will also try and tell you some troubleshooting steps that you can try.

First of all, disconnect your battery from back of the laptop, and try to power your laptop without the battery there, if it powers up, then just get a new

battery.

Second, get a screw-driver, remove all the RAM(memory sticks) at the back of it, clean their interface with an eraser, and try to power it on first without

them, then replace them back and power it on.

Alternatively,

Remove all your RAM(Memory Sticks), and clean the tip of the connector with an eraser, and re-insert it one after the other.

That is, if you have two of them, after you insert the first one, put on your system and see if it works, then do the same thing with the other one.

If the two of them works, them insert the them all. but if it is just one that worked, just remove the other one that is not working and replace it.

Also from what you have just said, I suspect that your hard drive is likely to be corrupt, or having a bad sector on it.

To be sure of this, disconnect your hard drive from the laptop, and power it up without connecting the hard drive, if it boots up to the point where it says:

"Operating System Not Found" or "No Bootable Device Found", then that shows that your hard drive needs replacement

Kindly Let me know how it goes.

Hope this helps.

Goodluck!

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.

try to boot ur laptop with disc manager cd or win XP.
if doesnt works then try win 98 cd and delete ur C:/ partiton and install new vista

try removing the battery and just run off power cord this may be a bad battery seen it before

given the symptoms, it points to motherboard.. if it was processor, video or ram. it wouldnt boot at all and you'd just get error beeps from your laptop. i'd first try resetting the bios, by removing the bios battery for 30 min, then putting it back in. if that doesnt work try changing it out, usually costs under 8 bucks. if that doesnt work then I would change out the motherboard, if its cost effective.
