Question about Sony VAIO VGN-FS640W Notebook

3 Answers

CMOS Battery My Sony Vaio laptop stopped working when you turn on the laptop nothing happens. Tested the hard drive on a friends Vaio and it booted ok and I tried my friend's hard drive on my Vaio with no luck. Connected an external monitor but again. The hard drive sounds as though it is spinning but nothing else on the system board works even a boot CD. Can you tell me if a Sony Vaio Model VGN-FS740/W has a CMOS Battery and where I can find it. The laptop was losing time and I recall update Bios message (or maybe it was my imagation). For the Product below the closest model was the FS640 but I have the FS740. I have the Back cover and the keyboard off but I can not find a CMOS Battery?

    My vaio used to exhibit the same problem that you guys had. After a few months of leaving it lying down, I thought to give this a try. Took out the battery entirely and just use the laptop with together with the AC adaptor all the time. Since then it never had a problem.

    Only thing is, the cmos batt needs replacement and i have opened my laptop for the nth time and i still couldn't find the damn cmos battery.

You want to be looking for the rtc(real time clock) which is a little unit not much bigger than ur thumb nail.next to it youll find the battery(sometimes heat sealed with plastic.)if you remove this battery for about 5 mins then replace it or in ur case maybe renew it this will reset bios to factory(also method for bypass passwords as every thing is reset)
you might also wanna check ur video card.(connections and dust)

Hi,

I have a problem. I guess free money or a new job would be an okay response from this post, but I am really hoping to get some information. I have a Sony Vaio VGN-FS640/W. I was on vacation, and when I returned the computer would shut down after every time the power cord was unplugged. It seemed as if there was no battery.

I chatted it up with the lovely customer service types at Sony, tried all the suggestions, and was assured that the next one would be the solution. Placation aside, which was nice and hope-inspiring, I am still at an impasse. The computer does not recognize that I even have a battery. I have tried all the "by-the-books" methods of troubleshooting. Can a battery die that suddenly? Should I take it to a service center of the Best Buy variety before mortgaging my non-existant house for a new battery? Thanks and I really appreciate any advice that I can get on the topic.


At Wit's End,
Marc

When I turn on my computer it says No operating system!!


There are a few reasons this can happen.

1. The hard drive may have failed,
2. CMOS settings may have disabled the hard drive,
3. Operating system file(s) may have been corrupted.

Hopefully, it is number 3. To attempt to fix it, learn how to boot into the recovery console from your OS CD, and execute CHKDSK /P to attempt file system repairs.

Hope this helps.

To reset the BIOS password read the information from this link.

In case of your laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

Sony VAIO PCG-8X2L will not boot. it loads the VAIO logo and sticks right there. no bios no post.


You have a currupt bios firmware. You need to pull out your battery, and disconnect the Cmos battery. Next leave it for at least 24 hr. to make certain you clear Cmos. Now get the latest bios update and have it ready to install. Make certain your a/c power supply is attached during this process. Put in a bootable cd with the firmware on it and see if it loads the new Bios firmware. You can then try to boot the Laptop or PC. I have had good luck doing it this way on most laptop's. Good Luck Phil
I have seen some cases where it is a motherboard problem, but not very often. I have also seen where it is caused by defective memory. You may want to test your memory in another laptop or borrow a chip to see what happens.


P.S. Here is the link to your bios firmware.

Can't boot and forgot bios password on ibm r50e


You need to remove, or short, the cmos battery. I'll be on the motherboard somewhere, possibly under the keyboard. Remove all screws, carefully, slide back any tabs on the keyboard and carefully remove. Only do this if your warranty has expired.
