Lenovo N200 3000 0769, laptop switches off during windows loading

[Whaat]

Hi everyone

I have Lenovo N200 3000 0769 series laptop with windows vista bussiness 32 bit. I bought it just two months ago. Since last 3 weeks I have a problem that when I start my laptop it goes upto the point where windows is being loaded and it switches off completely. Then I start again and it gives me the option to either choose "system help to recover" or "normal system start up". I choose system recovery and then it starts Think Vantage recovery tool and finds out one error and recover my system. After restart my system starts fine and works OK. But next time same things happens, i.e at the first try my system always switch off during windows loading.

Please help me to get rid of this problem.
Thanks

 I have had the same model laptop for 5 weeks, and exactly the same problem when starting up after several hours of being shutdown. (When it goes into the recovery mode after I switch it on again, I have been choosing the start up repair option. Interestingly today I chose the normal windows start option instead, and windows started normally).

Does anyone have any suggestions about curing this problem?

having definitely the same problem and waiting for a solution from admins!!!!

Follow start->Control Panel->System->Advanced->Boot options

Find checkbox "auto reboot on windows crash" and uncheck it.
next time when windows crashes you'll see an error code and  also the name of file that caused crash.
Posting them here will help a lot. The best way is to make a picture of the screen and post it here.

Time for you to have some fun... I had this problem once also..

Buy one of those aerosole canasters that blow out compressed air, most electrical shops have them, they normally come with a little straw so you can direct the air into small spaces...

Open up the compartment of the holds the fan, (Don't start unscrewing the whole thing, just that compartment) remove the fan by unclipping it, go outside and blow all of that dust off the fan using the air canaster.

Now here is the important bit, there should be an external vent close to the fan, moving into the pc from this vent you will see a metal mesh thing with what looks like a sponge (FULL OF DUST) then taveling from there there is what looks like a long copper train track, this is the "Heat Sink" guaranteed that vent is full of dust so take the laptop outside and use the canester in and around that area, just havea good look in there and make sure you got rid of all that dust... sometimes big clumps of dust fall off so be sure to find them and remove them also....

Not connect the fan and screw the bay cover back on...

You are now good to go...

I've had exactly the same problem, you reckon it's related to overheating caused by dust in the fan and not a BIOS or other hardware/software issue??

[DrunkenNinja]

Yes, when dust builds up the fan cannot do it's job, this happens with games consoles, desktops and a lot with Lenovo Laptops using the system I posted above will help the pc run much quicker, not freeze and not shut down...

I do this at least every 6 months...

I tried cleaning out the fan and associated vanes however there wasn't any dust in there and it was pretty clean so not sure what's causing this?? It seems to happen only when Windows is loaded etc.

Hi,

i have got de same problem with my Lenovo N200 0769. But I can't see a continuity by this problem. I tried to clean the fan but the fan was cleaner when a operating room. I also tried to update the Bios but i wasn't successful because i get en error (error code 5). Has someone an idea? I will describe the problem again. Sometimes the laptop is breaking off during the windows start up and shut down. It's like i would press the start up button. If i start the laptop after that i get a display an i can choose between "normal Windows startup"and "Startup repair". If i choose "normal start up" the laptop will break off again.Choosing the "Startup repair" the Lenovo care center comes up and is repairing the Startup. After this process I can start Windows in the normal way and it works. But sometimes the last changes at windows aren't available. (for example I installed MS Office and after the last startup repair the installation wasn't available). 

Has someone an idea? Bios update doesn't work (error code 5) and a new installation of Windows Vista even doesn't work.

Thank you for your help.

Hi !

I know nothing about Windows Vista..

But, you may want to check that it is either hardware related or software related.

In order to do so, download a Live CD version of a Linux operating system (Knoopix or Ubuntu comes to mind but there are Fedora and others available). Run the laptop with the live Linux (it won't do nothing to your disk unless you choose to install it, of course).

If the flaw is hardware related , you should notice the laptop shutting down ala Windows. Othewise it will run just fine.

Then you know what to   do exactly !

Hope this helps.

P.S. of course, if the flaw lies in the disk drive, this won't tell you !
