I apologize for cross posting but I misposted this in the another forum. Anyway, my first and perhaps only Vaio notebook, PCG-F480, was not charging the battery proper and now no longer even detects it. I had this problem with the previous battery. Believing in Occams razor, I figured the battery was failing and purchased a new one from CompUSA. After using it for a couple of weeks, I noticed the battery performance degrading with respect to the battery duration. Now the battery isn't even recognized by the BatteryScope software. The battery characteristics aren't even displayed anymore. I have all the latest FW (circa 2003) and software updates for W2K. I don't want to spend money on a new MoBo (>$200) if it's the power management circuitry. I'll just use it as a desktop machine and avoid Vaio's in the future.

Any clue? TIA.

Maybe your AC adapter isn't working. Can you try a different one?

This particular problem could end up being several different problems. I would take these steps:

1. Update the BIOS with the most current ver. (Make sure it's the right model.)
2. Restore the laptops Operating System. (Backup what you need.)
3. Update all drivers. (Sounds weird, but it sometimes causes this.)

If you are still having complications, and you know that the battery is good. Then, I'd say it's safe to say that your battery board has gone bad. This is the board that manages where and how much power needs to be distributed to your laptop from battery power. It also gives the battery the charge. It's not acually the Mobo, but a Daughter board that is connected to the Mobo. Sony is pretty well known for this type of error. I've seen it quite a bit. Good luck.

Has anyone keyed in on what exactly is the problem here? I have the same problem my notebook only runs on ac adapter - software doesn't recognize teh battery. If i have to do a BIOS upgrade - tell me there's a better place to do that then through Sony.
- A funny incident; talked to a sony CSR they had the audacity to ask me if i had the battery fully pushed into my notebook - morons.

Never got anywhere with this. I replaced the AC adapter and battery. The local authorized service center suggested I replace the system board (not the battery board) for a mere $200+labor with no guarantee of closure. Apparently, the system board was the field replaceable unit. I was livid. Since then, the Vaio has sat in my kids room plugged into the wall as a desktop PC opposite a new Dell Dimension. The Vaio was my first and, to this day, only Sony PC. I'm sticking with Dell and HP.

I'm not sure this is the same problem, but suddenly my batter doesn't charge at all, although the diagnostic says battery life is 100% (and there's no reason why it wouldn't be; I almost always use the AC). Should I try a new battery?

I have the same problem with my HP pavillion zt1150 notebook, so it's not just a Sony problem. Windows xp supposedly recognizes the battery, says its working properly and that it's charged 100%, but when I unplug the adapter, it dies. This started happening to me after I installed windows xp pro on my computer (it came with xp home preinstalled) I tried switching back to xp home using the original disks that came with the computer, but no luck, still no power from the battery. This leads me to believe that this might be a driver or bios problem... if so does any one know where to go to find updated drivers/bios???

thanks!

On the HP i tried running the battery configuration, but as soon as i get to the menu and press 'C' to configure, the computer loses all power and shuts off. After it shuts down I cannot power it back up until i unplug the AC adapter and plug it back in. I'm not sure what this means....

I have a sony laptop battery problem as well. I have a PCG-SR27. One of the battery locks fell out of the computer as I was using it. The piece was broken. As soon as I ralized that the lock had fallen out I looked at the battery status to ensure that I wasn't going to lose my work. The battery wasn't charging even though it was connected to AC power. This happened several months ago and the sitution has not changed. I sent the computer to an authorized Sony repair center. They said that I need a new mother board to fix my battery problem ($700!!). Does this sound right? Can a simple act like the battery lock falling out require the replacement of the mother board? My feeling is that the battery is not capable of charging without both battery locks in place. The repair center is insisting that the mother board is bad and they have not even bothered to replace the missing battery lock.

There is a thermistor (in the battery on the circuitboard) that opens frequently on the newer HP/compaqs.. This will give you a dead battery.. Common occurance on these. The biggest problem is trying to break a case open to repair them. It generally makes junk out of the plastic casing and you are better off to buy a refurbed one instead.. If its showing 100 percent it still does not mean the batterys good.. Try replacement first and then go for repairs. There are components on the system boards that fail as well as the batterys circuits and LI-I cells..

Replacement of the battery and AC adapter for the Vaio did not fix the problem. Hopefully, it works for the HPs. I've owned HP Omnibooks in the past and have never had any power management problems with them, though.

On the Sonys its generally caused by the converter board..

Ken,

Is the converter board a daughter board on the Mobo? Is it field replaceable? Is that the $200 or $700 part? Or hopefully less? TIA

It is a daughterboard and the board itself runs 80-120 new. I would call it field replaceable, just take your time. Might find them less used. I also might have one around here. Let me know if you can't find and I'll look mine up.

Matt,

Do these converter boards have part numbers? I'd hate to get the wrong one. Does Sony sell them direct?
Thanks,
Wen

I really wish I had discovered this site months ago! My Vaio, after months of the same battery problems described by many, MANY postings here, has died!

It won't run off D/C. It won't start up at all. What's a gal to do?

The part number is commonly listed as PWB PWS-14 - if you like I can send you a pic of the board to compare with what you are looking at. I have a blown one and a new one. I looked at a three web stores that had them but none included pictures. You can search others, I have seen them pictured before. Let me know.

Matt.

Thanks for the inspiration. For my PCG-F480, I believe I will need the A8046-835-A Vaio Laptop HD/Battery board. Do you know anything about installing this particular card? Is it field replaceable? Does it require special tools? I'd hate to replace it and have the whole laptop die:-).

Wen
