For the past few months the lithium ion battery on my wife's computer
has been losing it's capacity. Now it's gotten to the point where it won't keep the computer running more than a few minutes in the event of a loss of AC power. Up to this point this hasn't been a problem because my wife never really takes the computer out of the house. A few weeks ago she started asking about getting a new battery. (You never can predict these things), and so I investigated this. I knew I'd have to make some kind of arrangements eventually, but truthfully with Batteries Plus asking 79.00 and the cheaper online offers questionable at best, I haven't been eager to jump into this, so thus far we haven't done anything. The other day she told me about a new problem that she'd been having with the computer over the previous two weeks or so. It seems that every so often instead of the computer going through post and then booting up, a few seconds after you attempt powering it up a blue rectangular box pops up with a black screen behind it. Inside the box is an "enter password" message. Neither of us have ever seen this box before, nor do we have any idea what "password" it's looking for. (Our usual ones don't work). I tried removing AC power as well as the LI battery for a few days but this had no effect. Toshiba has a 24 hour tech line that if you're lucky enough to connect to a intelligible person might be of some help. So I called them. The Indian girl seemed knowledgeable, I could understand her, and she suggested that the message was asking for a "CMOS" password, which she said someone must have put it into the boot sequence. I've never heard of anything like this and I told her that it was not possible that anyone in this house could have installed this into the computer. I know that I didn't, and I'm only slightly more computer literate than my wife, which is not saying much. The tech suggested that we will need to reset the CMOS by pulling the internal battery. According to her, the battery could be defective as well. Now I can certainly pull the battery and replace it as well if need be, however I have my doubts about that being the cause of this. This laptop is not that old and I have to question if this is what the problem actually is. If it is in fact a dead CMOS battery, why would it lock me out of BIOS? And if it isn't, why did it happen in the first place? Unbeknownst to me my wife has stored all the Grand Children's pictures on this computer with no backup anywhere else. So if anyone has any rabbits they might be able to pull from their hat, I'd really sincerely appreciate any advice. Thanks, Lenny |

Neither of us have ever seen this box before, nor do we have any idea what "password" it's looking for. Satellite A205, model PSAF3U-0NROOV is NOT the model numbers. Look on the serial number sticker for something like: A205-S1234 where 1234 is some other number. That's the CMOS password. Google for "Toshiba CMOS password reset". You might be lucky and find that just removing the CMOS battery (and the main battery), leaving it sit for maybe an hour, replacing the battery, and trying again, might clear the password. Here's one method for an A205-something laptop: http://www.techspot.com/community/topics/how-do-i-reset-eeprom-on-toshiba-a205.102975/ There are various schemes and tricks that work on different models. http://www.cgsecurity.org/wiki/CmosPwd I believe that the laptop is old enough that the parallel port reset trick will work: http://www.cgsecurity.org/wiki/CmosPwd#Toshiba (near bottom of page). Incidentally, there's nothing your wife did that caused the problem. Some laptops spontaneously set a password for no obvious reason. It's a bug that was probably fixed in a BIOS upgrade, which you probably didn't install. Toshiba claims that for "security reasons", they do not offer a password recovery method. They assume that if it's locked, you'll buy a new laptop. My customers reaction is often something like... right, any new laptop except Toshiba. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Be careful in there. Look at the harddrive and see if it is a Western Digital. (I know it sounds a bit off but it's true that it is possible)
The reason for that is that some WD drives do all the sudden start asking for a password. It happened to me. All I did was enter setup one rime to see if I could disable the webcam (I thought it might be the source of another problem). At this point if all it says is enter password, it might be a HD password. You have no way of knowing unless you have seen that password box on that unit before. If you want some info on it just google for "WD1600BEVT password". Those drives were used in Toshiba laptops as well as my Gateways. There is a procedure you can do on a Toshiba that fixes it but it won't work on a Gateway (lucky me), however it invloves copying and pasting some code from a website and then making a bootable CD or thumbdrive and all this crap. I found this is a common problem with the 160GB models but nothing indicates that it is exculsive to them. There's no reason it should be. At any rate, if you can get the thing to boot, get a bunch of thumbdrives and get every picture and everything backed up ASAP. I mean do that first. If it boots, leave it running and turn off the power saving so it doesn't shut itself down. After you have the backup, see if it does have that type of drive and let me know, I'll see if I can find the code and the instructions again. However beware, I do not know if recovering the drive with that method saves or destroys the data. J |

"My customers reaction is often
something like... right, any new laptop except Toshiba" I remember in the real old days they had some code you had to copy to a floppy to reset the password. It makes sense they just don't do tht anymore. Think there's any chance of getting a procedure like that some other way, like by figuring out the chipset or somethng ? I hope it's not too stupid a question, I am not quite a guru. My advice here is based on personal experience. HA, I won't nut another Gateway after this, I found all kinds of things out about these things after while. For one - seriously substandard sound. I tried plugging it into a decent amp and speakers and UGH. Terrible. Then I find out that there is no preset "flat" on the EQ, I had to set it manually ! The camera software sucks ass and what's more that HD password issue keeps it from booting any other media just being there. I even excluded it from the boot menu and it still won't boot past it. GRRR. (supposedly that is not true of the Toshibas with the same problem) Actually while you're here, just what kind of laptop would you recommend ? Maybe an Acer or something ? J |

Gateway, eMachines, and Acer are all the same thing, and pretty much all of their models are flimsy junk. Also stay away from anything made by Toshiba, the power jack breaks on most of them...I've seen 22 Toshibas in the past year for a variety of problems, all but 3 had a broken jack. Look at reviews if considering Sony. The high end stuff is quite nice, but quality of the lower-end stuff seems to vary by model. I personally like the HP Probooks and Dell's Vostro and Latitude stuff. They're a bit more expensive (and things like a webcam are often extra, these are mostly sold as enterprise units), but many models from those lines can take a serious beating. Many models will probably obsolesce before they break. Also, at least in my experience, they came with limited bloatware that actually uninstalled cleanly, so you don't have to format as soon as you get it. |

And it appears to be one of the models covered by the procedure under the first link that you sent me. I thought that it was interesting that pulling the CMOS battery as one guy had tried) didn't help at all. This automatically created password **** reeks of "virus", and certainly must be a nice little money maker for the dirt bags at Toshiba. Almost like the *******s designed it to do this. Thanks a bunch guys, I'll get into it this week and let you know if it worked. Lenny |

Now it's gotten to the point where it won't keep the computer running more than a few minutes in the event of a loss of AC power. stored all the Grand Children's pictures http://www.IrisVista.com , a website dedicated to Toshiba laptops, is great for repair information. Iris refers to Toshiba's awful Ask Iris help database at their website and is what their level 1 and maybe level 2 tech support have to rely upon for all their information. If you want real help from Toshiba for their hardware, ask for level 3. OTOH their software tech support seems decent. I also have an A205, and it's not difficult to remove the hard disk to make a backup with a desktop machine or with a SATA-USB adapter: http://tinyurl.com/mmhl7o http://www.irisvista.com/tech/laptop...assembly-1.htm Remove the screws from the lid on the bottom that covers the hard disk, then slide the disk toward the edge of the computer to disconnect if from its SATA data and power connectors. Pull up on the flexible plastic strip to remove the disk. Clone it to another notebook hard disk, in case the original disk fails. Notice the disk is set inside a metal cage, and you'll need to use that if you replace the disk in the laptop, or else the disk will flop around inside and maybe even unplug itself. There are cheaper sources than Batteries Plus, like almost every place except Toshiba themselves. OTOH be careful about buying really cheap laptop batteries because some of them don't contain a temperature sensor to tell the computer when to stop charging but instead they have a fake sensor (fixed resistor) that makes the computer charge at a low current forever, rather than stop when done. That can be really bad with lithium batteries, which are particular about how they're charged. If the Toshiba doesn't grossly lose track of time, then I seriously doubt its internal CMOS battery is bad. OTOH if you do replace it, be sure to get a RECHARGEABLE lithium battery for the CMOS because there are non-rechargeable lithiums that look just like it and even have the same cable attached. |
