Satellite A100-495 - Win7 show too high battery voltage

Hello

I upgraded my laptop old but reliable (A100-495) too Win7 X 64.
Now, I recognized that Win7 Manager energy shows that 67% remaining at full charged battery...
I checked with several energy programs - all expect a 15V for battery voltage.
But the A100 battery only have 10.8V.

This happens with 3 different batteries.
Does anyone else have this problem? No idea how to say that the battery has only 10.8V to Win7?
I tried to reinstall the drivers from the battery and ACPI - but it did not help.
Multiple load / uncharging also showed no change.
The best battery last for about 90 minutes, not too bad but battery starts already after 30 minutes...
Allows you to change the values of caution - a little - but even after to 0% it works for about 20 minutes...

Any help appreciated ins

concerning
BR,

> But the A100 battery only have 10.8V.
Looks like the battery nears the end
How old is the battery?
Each battery would start to lose own performance after about 500 charge cycles.
This should be considered.

  • Satellite A100 - 495 (PSAA9) - CPU and GPU upgrade

    Hi all

    I have a few questions.
    I have a Satellite A100-495 with 2 GB of Ram, Core2Duo 1.83 GHz (2 x; T5600) and an NVIDIA Geforce 7600go.
    I want to spend the CPU and the GPU. Is this possible?
    I don't want to do. I am looking for a store (if possible in Germany) that can do this.

    If its possible, what it costs? And what store can I speak?

    If this is not possible-> why? It is fixed; It getting too hot?

    What solution do I? I don't want to buy a new laptop.

    Kind regards
    Dave

    Update CPU and GPU on laptop computers is complicated enough or is not possible. At first, I must say that GPU is part of the motherboard and graphics card can not be upgraded at all.

    What about the CPU upgrade? Toshiba authorized service providers will not do that and the CPU upgrade is not supported. Few people on this forum have talked about CPU upgrade, but for me the risk is too high. All hardware components are adapted to the work well together and also to reduce the risk of damaging the material. The BIOS is also suitable for the specific hardware configuration. The values of the fans are also tested and there is no risk of overheating.

    Change CPU, you will get no more powerful laptop. Modern processors are powerful enough and a few MHz more won't do anymore difference. What you can do is to increase the RAM to the maximum level - 4 GB. That s all what you should do and your laptop runs a lot faster.

    Also be careful on the configuration of the operating system. This will also help make your laptop faster than before.

    By the way: for operations you need more power? What you want to do with your laptop?

  • Satellite A100-383 does not start - not battery

    Hello.

    I have an old Toshiba Satellite A100 - 383.
    Recent months its battery will remain as defendant for 20-25 minutes.

    OK, that's an old laptop, it's normal, I thought... I connected the laptop to the grid and I haven´t you have any problem. I stayed several hours with the laptop with no problems.

    But yerstarday, the laptop was closed suddenly and now, do not start. I see that the battery symbol flashes 11 times.

    So I have a few questions:

    1 - this laptop, works not connected to the network * without * battery? I thought it was possible...

    2 - What is the problem? Battery? Charger? How I know this?

    3-If the problem is the battery, how much would a new?

    Thank you very much. (and sorry for my English).

    > But, yesterday, the laptop was closed suddenly and now, do not start. I see that the battery symbol flashes 11 times.

    Usually the laptop automatically stops due to high temperatures. Is the kind of physical protection, but after a few minutes, you should be able to turn on the device, the led flashing could mean that there is a problem with the electronic power supply on the motherboard means that the motherboard is affected.

    You can try after bypass. :
    Remove the dough (if it is not already removed), unplug the AC adapter, press the power button / stop for 30 seconds.
    Now, plug in the AC adapter and try to turn on the unit.

    > 1 - this laptop, works not connected to the network without battery? I thought it was possible...
    Generally, it should be possible to use the laptop without the battery.

    > 2 - what is the problem? Battery? Charger? How I know this?
    Not easy to say: If the laptop powers not even using the power adapter, a power adapter or the motherboard might not work. If the two parties must be verified by the technician.

    > 3 - If the problem is the battery, how much would a new?
    Don t think that its battery from the laptop should run with adapter only

  • Satellite A100-495: strange starting problems & freezes

    Hey guys.

    I recently got my Satellite A100-495 back from repair - it had a power problem (no led was flashing and it does not start of course). They told me that the motherboard has been renewed.

    Now, I have the following two issues:

    (1) it freezes suddenly sometimes in windows after 1-2 hours of operation without problems and I have to hold the power button for a few seconds restart

    (2) I press the power on button, LEDS are underway but the screen remains black, sometimes becomes gray, hard drive makes noise, fans going on but it just does not start, do not show anything. After some tests, I have to start but once again crashes after a couple hours of functioning properly.

    Can someone tell me what is the problem here?

    Bad memory (RAM) can cause this.

    If you can get it to start, test the memory with Memtest on a bootable CD. www.memtest.org

    Otherwise, try the combination of the different memory card. If you have 2 sticks of memory, try with one stick, then try the other stick, try different locations.
    Often the memory pins can oxidize and cause problems. To clean the pins, use a pencil eraser/rubber and rub the pins of module memory.
    Be careful when you handle the memory, you can zap easily memory with static electricity. To make sure that you are connected to the earth when the memory handling.

  • Satellite A100-495 - Intel 3945abg wireless network card cannot find wifi networks

    Greetings,

    I have some problems with networks wireless on my laptop Satellite A100-495.

    The problem is: my wireless adapter (intel / pro 3945abg) doesn't seem to find wireless networks. If I portable place very close to my router wireless (such as 1 m) - connection can be established. If I move away (~ 5 m)-no connection or 'very bad' quality and constantly broken. Other notebooks I've tried still have "very good" quality at the same range.

    This happens with other routers as well. And I can not any sign of wi - fi in my Uni (my colleagues have no problem with their machines).

    I tried to play up with some parameters. Reinstalled adapter. Downloaded the latest drivers. Nothing helps.

    A tip? Thank you in advance.

    Hello

    Something like that happened to me a long time ago.
    I used the Wlan configuration option to own Windows. For several months, I use the Intel Proset configuration utility to establish the WiFi connection!
    It works!

    In addition, I have disabled the power Wlan option in the Wlan card properties save and adjust the intensity of the signal at top. I remember, in the advanced properties, you can find the 802.11 option preamble. The value is Long and short on my laptop.

  • How to Exchange screen cracked on Satellite A100-495

    Hi all

    My sister gave me his Satellite A100-495 to repair broken screen. Now, I am looking for an instruction open Notepad and replace the TFT, but I can't find one?
    Someone who could give me a link?
    (And Yes, I know not to risk... ;-))

    KR, komo

    Dear KOMO

    Please don't get me wrong but replacing the screen is quite complicated, and for that you need some manuals with accurate description how do. Unfortunately this document isn't public and you do not download.

    So the question is what to do now. As Akuma has already written you can Google around and maybe find something, but you have to understand that everything you do is at your own risk. Maybe you should seek professional help. It is better to pay a little bit and it will be well and properly. No you don't have to do this a Toshiba service.

    Check all possibilities and try to find the best deal.

    In any case, good luck!

    The problem is when I suspend it for more the a few minutes when the fan is running at high speed. This occurs on both Windows XP and Linux GNU. When the temperature of the two nuclei will more then 51 degrees C fan slows down and begins to work as expected. Suspended for a short time (about a minute or two) the fan speed is OK.

  • Satellite A100-495 with extern Widescreen Display

    Hello!
    A year ago I bought a Satelite A100-495 and now starting with photography I need a second display (external) to get a bigger view.

    The problem I have is that the external screen didn't work the right way.

    I just tried two widescreens 19 "(tout comme un test... va pour un 20" SyncMaster) but if I selected to widescreen solutions (16/10 like 1280 * 800pix wich is the hightest 16/10 to chosen at the moment on this laptop) the display shows just seen unclear (no clear edges)! "

    solutions of 4/3 as 1920 * 1440 are appear as clear and cool as it should (both: standard and widescreen displays... only expanded on the big screen, but with clear edges)

    Now the problem to slove is: I want to install a large screen with a solution of widescreen (16/10) and has an unobstructed view.

    Anyone has a solution to slove this problem or even having the same problem?

    Thanks for the helpful answers!

    The problem is that if the graphics driver doesn t supports the resolution of your screen favourite so you won't be able to choose and use!
    What you could do is to update the graphics driver, but I can't give a guarantee it will help

  • Re: Satellite A100 and Win7 - screen is not appropriate in all of the screen

    Nice day

    I upgraded my Satellite A100-232 yesterday to Windows 7 32 bit. The installation went according to plan and installed everything perfectly. My problem I encounter is that the screen only covers 75% of the screen. The resolution is 800 x 600 and I changed it to 1024 x 768. Does the screen a little bigger, but still no connection in the entire screen.

    Can someone please help with this problem?

    Thanks in advance

  • Satellite A100-237: what are the compatible battery packs

    Hi guys

    There is no compatible batteries listed under the 'available options' tab for the A100-237, which I find hard to believe.

    No one knows the number of part/model of the standard battery, the extended battery pack and battery high capacity?
    My battery is completely dead and I need a replacement.

    Thank you!

    Hello

    I couldn't t believe that and that's why I ve checked the Toshiba Options European and accessories site.
    It of a nice page if you need any information on compatible parts and additional devices.

    However, I found this battery support.
    Battery Pack (6 cells, 4300mAh) PA3399U-1BRS
    Battery (Li-ion, 4000mAh, 6 cells) PA3465U-1BRS
    Battery (Li-ion, 4300mAh, 8 cells) PA3457U-1BRS
    Extended capacity battery (Li-ion, 6000mAh, 9 cells) PA3478U-1BRS
    Battery Pack (Li-ion, 12 cells, 8600mAh) high-capacity

    As you can see there are different farms with different power capacities.
    If you are going to buy a large capacity battery, you should be able to use the laptop much more time with the power of the battery!

  • CPU in Satellite Pro U200 temperatures are too high

    Hello

    I'm a little confused / concerned about the temperature of my CPU (Intel T7200) in my Satellite Pro U200-199. The confusing thing is that the case temperature is generally higher than that of the junctions of the two nuclei, which is the opposite of how it should be.

    Everyone knows this?

    As well, the case temperature is higher at seems reasonable, even in basic use. Basic use of office applications takes the temperature to 49 c, and then everything above that (opening an application for example) increases the temperature has high degrees of the years 50 or 60. Under a larger load, temperature (T-box) goes up to 65 C.

    One of the consequences is that the fan is on most of the time.

    I would like to know if there is a problem with the measurement of the temperature T-box is measured correctly, or if the processor overheats. If the measure is a fault, then do nothing about this? Like changing the BIOS?

    I should mention that the computer is only a week and has a BIOS update.

    Any ideas or help greatly appreciated.

    David

    Hello

    The temperature of 50-60 degrees is not unusual. But I wonder how you measure this temperature or what tools or utilities did you use?

    Usually the CPU is not only responsible for the temperature inside the laptop.
    The graphics card and HARD drive also produce heat which increases the temperature of the laptop.

    Anyway, the computer supports protection against overheating. This protects the laptop and parts from overheating.
    If the temperature reaches a critical threshold the laptop would be automatically stops down
    but it seems that the laptop works properly so in my opinion that you should not be worried. ;)

    Hello

    You must install VAP and Support of Flash Card Utility for the FN keys works!
    Installation of VFR will not help you if you should not install Flash memory card Support utility.

    As far as I know, these two tools are not phone specific, so you can choose the VAP and the published Flash card for example utility for Satellite L500!

  • Satellite A100 (PSAA9) is not charging the battery

    I have the original (10.8 v, 4000mA/h) who suddenly died battery, the laptop don't see (energy saving does not detect the battery), but when it is connected to the charging LED is on and it stays on for 8-12 hours.

    I bought a new battery, the laptop he detected (see energy saving), after completely discharging the battery I have pluged in the AC adapter (laptop off) and waited for 12 hours, when I turned on the laptop, the battery was at 0% cost in energy savings, the reading is correct because the laptop does not start without AC pluged, the new batt is dead too.

    -bios version v6
    -Repeat the process charing time and time again (12 times with the laptop off & on)
    m ' help to restore the bios? (If so, how to get an older version of the bios?)

    All tips that might solve the problem are WELCOMED.

    If you have the original Toshiba battery and the problem persists, I fear there is a problem with electronic power supply on the motherboard.
    Contact the nearest authorized maintainer to check the electronic card.
    They use diagnostic tests and special tools and they can for sure what is wrong there.

    Forget the BIOS and these solutions. He won't help at all.
