Lenovo 3000 N200 will not Boot

I have a problem with a Lenovo 3000 N200 which will not boot. When I press the power button, the power led lights up, the fan rotates shortly and then stops. Nothing more happens, no beeps, no picture (neither on the laptop display, neither on the external).

I removed all external devices and modules: DVD, WiFi, HDD, RAM, battery - no change. I tested the RAM on another machine and it works fine. Even if I start the laptop without RAM, it's the same behavior.

This thread has the same issue described: A guy mentions:

The same thing happened to mine. It was a motherboard fault that Lenovo are very familiar with, apparently related to the CPU temperature.

One thing you can try is to keep trying to boot it, if it's the same problem the CPU will eventually warm up enough for it to boot and run ok.

I tried keeping it on for a while and I noticed that it's getting warmer. There was no change in the behavior though.

I can have some experience in opening, cleaning and fixing small problems with laptops, so I can do such repairs if I know what to look for. Changing the motherboard and/or the graphic card is not worth it though (they cost $150+ on eBay).

Any suggestions what to try?

Not alot really as it will be motherboard related. The chap you quoted is quite right, I worked with a few of these and they had the same problems.

It tends to be a fault with the boards, or they do something similar where they shut off right after turning on. This was due to the thermometer thinking it was too hot / cold and shutting down.

I had to have the boards replaced under warranty or laptops chucked away.

CPU's overheating. That's why it's shutting down and the fan stops. At least, that's what I think without looking at it. I've seen that issue happen. Unless you have something you can put directly on the CPU, and you don't want to spend money to replace parts, you may just be looking at a new machine here. Check the CPU temp in the BIOS (if it has that capability, should) and see if its running hot. Well, if you can get that far.

@tobyweston: Do you have  any idea where thermometer is and what it looks like? Any idea if it's replaceable?


Unless you have something you can put directly on the CPU

What do you mean by put something directly on the CPU? I opened it up and tried to run it without a fan, same story, no difference.

I cannot get to the bios, it does not show any picture.

Not 100% sure. I don't think its a replaceable part as they always just replaced the boards.

Attempting a BIOS upgrade if you ever manage to get it on would be another option. I don't think this was the only laptop Lenovo did with this issue, and a few were resolved with BIOS updates.

the only thing to try is resetting the bios by removing the bios battery

I meant something like placing it on a laptop cooling pad or something of that nature. There's a bunch here:

Well, it's not running, so it's not hot. It does not have time to get warm at all.

Just for information, it did not work. I disassembled the whole machine and changed the parts one by one (I have another working one). It's definitely the motherboard, the video chip is working fine. However I couldn't find any solution to the problem so I will be selling it for parts.
