Froze during BIOS Update

2009-12-16, 12:51 PM

Lenovo 3000 n200 0769 BRG

 

As per the title my laptop froze during a bios update, I now have a €300 paper weight.

 

When turning on the fan spins, the cd tray works, but the screen stays blank and only a single power light stays on. I tried starting the machine with no RAM inserted to see if the bios would beep. It didnt.

 

I think i need to reset the CMOS  and in another thread there were instructions as follows " two exposed metal traces labelled CLRP1. You need to short those traces together for a few seconds."

 

I can get to the traces CLRP1, but it doesnt work.

 

Could someone please verify how to short those? What do you actually do?

I lightly pushed a flat head Metal screwdriver on the traces, also tried a paperclip,other screwdrives, and basically everything metal.

 

Could someone clarify what needs to be done? Thanks so much

If the bios is corrupted, yes, it may be bricked.

 

Search the web and these forums for "phoenix bios recovery"

there may be some hope. I have never tried any of the solutions

I have found about a Bios recovery disk.

 

The solution for a bios "hard reset" on my N100 was to dis-assemble

it to the point where I could short the leads of the bios backup battery

for about 5 seconds. The bios on mine was not corrupted, though.

 

Find the Hardware Maintenance Manual for your laptop model HERE

and look for how to remove the top cover. The battery is probably

on the bottom of the motherboard. A bit tedious and complicated

if you are doing something like this for the first time.

Thanks very much for the comprehensive reply, I honestly do appreciate it.

 

Its annoying how updating a laptop can cause it to break through no fault of my own.. but I' report back how it goes anyway.

 

Again, my thanks :smileytongue:

So I've successfully disassembled the laptop (the room is destroyed with screws and screwdrivers :P)

 

You say the back up bios battery, are you referring to the CMOS or is there actually a battery? What did yours look like? Googling doesn't yield any substantial results.

I tried shorting the CMOS, it can't be removed because its soldered on.

 

Thanks

*Sorry for double post*

 

I just realized that my battery had been acting up lately, it wouldn't charge while plugged in.

The laptop worked while running directly from the wall.

Would a broken battery interfere with the laptop as it starts up?

CMOS battery should be small coin sized silver battery.

There should be two leads going to motherboard,

short with small metal wire like a paper clip for 5 seconds.

Then restart and enter bios setup, and set time, boot order, etc.

 

Yes, bad main battery can cause many problems,

startup, random shutdowns, etc

 

I did a "hard reset" on the cmos battery when my new battery

would not charge.

 

Hope you remember how to put it all back together!

Fun, right?

Ah still no dice, pretty annoyed but thanks for your help anyway. The cd tray still works so i'm gonna make a live cd and hook the laptop up to a monitor in the odd chance it will work. If i don't report back take it that i sold the laptop pieces individually... Thanks duck3!

Did you find the battery? Where is it located?

 

Sorry this hasn't worked out, if you lived nearby

I would buy it from you!

Yup, definitely found the battery alright, was under the touchpad.

Gonna try this one more time, see if My laptop supports it.

I could get it repaired by lenovo, but id have to buy a new battery aswell so easiest option is to sell individually.

 

(btw I know I don't have to be as detailed as I am in my posts, but I don't want the next person to have this problem to spend as much time researching this lost cause :P)

The detail is good...

 

Since you have it apart, do the cmos battery leads line up with

or correspond to the CLRP1 traces you mentioned in first post?

 

Good luck.
