I have a Lenovo 3000 c100 model
Prod id 0761d7a
my charger gave out one fine day while laptop ws online...
bought a new one....charged it nice and good... even got the charger tested ...it wrked fine...but i cant boot into my windows XP
earlier I thought ,mayb windows got corrupted due to the power failure and tried booting with my linux live pen drive that i keep handy for such probs.....still nuthin....BIOS boots good..no check sum errors...the logo screen comes good...
but then it shows No bootable CD as always and then when i press F8 it even goes to OS choices and safe mode menu but it jus wont start booting the OS ....the linux pendrive i told u abt did run fine on this lappy before...
secondly i put in my xp CD ..still No Bootable CD .... Then I thought mayb the CD-ROM ws shot..
exchanged it with another model i have that i knew had a wrkin cd drive.......CD wont read.........
Then i tried assuming hard drive failure........ but hard drive is detected ok by BIOS and shows its name and everything and it does go to OS choices menu ....
Now some of my very important work is on that hard drive in lappy....
I can get the files by connecting HDD to another system using some adapter cable....but guys i need this laptop bad..........How bad???? really really bad......Please help me diagnose the prob....
thanxx a lot for your help...

The same thing happened to a laptop of my sisters.
I ended up getting a new hard drive for it, and reinstalling windows.
It was the only thing that would work. Nothing would boot with that drive
She was able to recover her files with external hookup.

I took out the hard drive and tried to boot it off usb but didnt work...
then i put the hdd back in and tried booting from network....viola it booted a version of slax(linux) from PXE
so now i know RAMs not the prob..... it was also reading hard drive files easily in that os
after about 3 mins of me trying to copy files the display went all fuzzy and i shut down the lappy
after that i now cant even get to the BIOS screen.... now wen i press the Power button the drive (device) access led lights up continously...fan runs.... but nuthin comes....even the BIOS logo has gone.. Pls help ....
this lappy is very important to me...... all help will be appreciated.....

My last solution is to find a way to remove or short the bios/setup battery.
This resets the bios to default, and your parameters would have to be
input again on first boot after reset.
I do not know where battery is or if it is accesible on your laptop without some
disassembly. The service manual, HERE, may help.
A "hard" reset of the bios by removing the bios battery, or shorting the leads
can fix a multitude of problems. Remove or short for 5 seconds should be

hi duck3 thanx a lot for ur help
cant tell you how grateful i am
i found another service manual and shorted the contacts
thankfully its back to its original problem of reaching the OS menu
and then with a fresh BIOS and the HDD removed i booted off a pendrive....it worked
the slax version i had on the pen drive had memtest 86 as an option so i ran that it passed each and every test..
i think u are very right that HDD is the prob I will test another HDD on it to see if it runs meanwhile searching for a way to do that as i dont have another HDD handy
any idea if i could use a desktop variety HDD instead using a convertor cable or smthin
i will get back to yu after 6-7 hours when i hv done further tests
again thanks a lot

hey duck 3
i got another HDD from a friend (PATA drives are rare these days..) and it booted just fine using his drive so it is the same prob that was with your sister's lappy..
i cant boot with that HDD but once booted the system works fine and reads that HDD too ....
now did you try and salvage the HDD from your lappy .. if yu did try tell me wat all u tried please
thanx a lot

Well good morning, I am glad to hear you have made some progress.
My sister still has the problem hd from her laptop, she was pulling files,
so I have not had a chance yet to test it. Sorry.
Best advice is to rebuild with replacement hd, and pull files from old
one. A tedious job. For the future, think disk imaging!
I convinced my sister to purchase two new hds and once her laptop
was all set up, I cloned the drive. Now, in case something similar
ever happens again, she can just swap in the clone drive and keep
Let us know how it goes.

got it working at last....
first I booted slax of the network(PXE)
then i backed up all my files to the pen drive....
shut down the lap
took out the hard disk ...booted slax from pen drive........
reinserted hard disk(RISK RISK RISK) while lappy being on..
did a zero fill from console on the hard disk
usually first 1m of memory is left unchanged to retain MBR bs=1m
but i thought a corrupted MBR mayb the prob
so i took out the MBR while I was at it... bs=0
turns out that ws the prob....
used zero fill with no MBR exclusion
then i used my XP CD to reformat
worked like magic....
try it on your risk but if yu do ...post here..
thanx a lot
