Question about IBM ThinkPad T23 Notebook

1 Answer

"False" battery low indication

My T23 will only run a few minutes on battery. The battery says 10.8V nominal on the case. When fully charged (T23 turned off) the battery voltage is 12+ Volts (I have two batteries, this applies to both. After a VERY few minutes I get the 'low battery' warning. The battery voltage is around 11.75V.
Obviously the battery isn't dead. What's wrong here?

    I have no way to check the battery under load. The voltage readings were taken with the battery removed from the PC.
    I could apply a known load resistance, measure the current and voltage and calculate the wattage. Is that what you're suggesting?
    If not, please elaborate. Is there a software 'widget' that would let me see the power usage in realtime?
    Thanks

Yea I think that might be your best bet, because battery life is measured in Wattage Hours.

You could try this piece of software

Why does my tom tom keep going the shut down page every 10 seconds I have pressed reset but makes no difference I ride bmw r1200rt


One possible cause is that your battery is low or the battery can no longer hold a (good) charge. In this case, the TomTom is shutting down because there's not enough battery to keep it running, even though it is plugged into a power source.

To determine if the battery is the cause, try to charge the TomTom battery .... using a (USB) connection to your computer, or a direct power source (i.e. while the TomTom is not being used). Let it charge for a few hours until the batter charge indicator shows that it is fully charged (or just leave it charging overnight).
Then, unplug the TomTom from the "charger" and power it up. If the TomTom (battery) doesn't hold a (good) charge, the device will shut down within a few minutes, e.g. 10 mins or much less.
When you (then) plug the device into a power source, and it doesn't stay on (i.e. it keeps shutting down after 10 seconds), you can safely conclude that the battery is the cause of your problem.

Tire pressure light is staying on in instrument panel. checked tire pressures. all correct


There are two typical types of tire pressure monitoring systems, direct and indirect. Direct TPMS uses individual battery powered sensors on each wheel to report tire pressure to the computer and if this is the case one of your sensors may have failed. Indirect TPMS uses a combination of values measured externally to each wheel (rotation velocity, temperature, etc.) then the computer calculates nominal values and indicates when a wheel is performing outside those nominal values thus indicating a potential low tire pressure situation. Any false indications with an indirect TPMS may be due to a fault within the ECU (computer) or other feedback sensor.

Check battery state


Same as a 12-volt cell, charge the battery fully first, then let sit a few hours.
Get a hydrometer from the nearest auto store, and measure the specific gravity of each cell (directions and measurements will be in the package). Each cell should read a value (for instance 1.20). If all are in the good range, then something else is going on. If one is low (for instance 1.0, while the rest are 1.2), try to run the battery down pretty low, then fully recharge it again, then retest. If same problem, that low cell is dying.

Not much you can really do about it though, once a cell starts failing the battery is pretty much done for. Although it'll be hidden some, because you have 24 cells averaging out to 48V, so a cell that should be "2.0" nominal, reading only 1.0V for instance, isn't going to make much difference.
However the rest of the cells are going to begin having problems quickly as they reverse charge through the dead cell, etc. It'll also affect other batteries, as they begin to reverse charge through the dying battery, or fail to completely charge (or overcharge) as a result of the charging circuit trying to get back to 48V. (If you only have 46V of nominal cell capacity (due to one dead cell), the charger is going to want to keep charging until it reaches 48V (actually higher, the fully-charged cutoff is above nominal, not going into that here). So basically it's going to overcook the rest, trying to get to that peak value that it wants to reach.

I drove it home and it was fine, i shut it off and within five mins i tried to start it and it would crank but wouldnt turn over, i tried a few more times and it nothing, but now my battery is going low...


Hello,

The first and most likely indication of a low battery would be a hard starting problem caused by slow cranking. If the battery seems weak or fails to crank your engine normally, it may be low. To find out, you need to check the battery's "state of charge."
A battery is nothing more than a chemical storage device for holding electrons until they're needed to crank the engine or run the lights or other electrical accessories on your vehicle. Checking the battery's state of charge will tell you how much juice the battery has available for such purposes.
If your battery is low, it needs to be recharged, not only to restore full power, but also to prevent possible damage to the battery. Ordinary automotive lead-acid storage batteries must be kept at or near full charge to keep the cell plates from becoming "sulfated" (a condition that occurs if the battery is run down and left in a discharged condition for more than a few days). As sulfate builds up, it reduces the battery's ability to hold a charge and supply voltage. Eventually the battery becomes useless and must be replaced.

The charge level depends on the concentration of acid inside the battery. The stronger the concentration of acid in the water, the higher the specific gravity of the solution, and the higher the state of charge.
On batteries with removable caps, state of charge can be checked with a "hydrometer." Some hydrometers have a calibrated float to measure the specific gravity of the acid solution while others simply have a number of colored balls. On the kind with a calibrated float, a hydrometer reading of 1.265 (corrected for temperature) indicates a fully charged battery, 1.230 indicates a 75% charge, 1.200 indicates a 50% charge, 1.170 indicates a 25% charge, and 1.140 or less indicates a discharged battery. On the kind that use floating balls, the number of balls that float tells you the approximate level of charge. All balls floating would indicate a fully charged battery, no balls floating would indicate a dead or fully discharged battery.
Some sealed-top batteries have a built-in hydrometer to indicate charge. The charge indicator only reads one cell, but usually shows the average charge for all battery cells. A green dot means the battery is 75% or more charged and is okay for use or further testing. No dot (a dark indicator) means the battery is low and should be recharged before it is returned to service or tested further. A clear or yellow indicator means the level of electrolyte inside has dropped too low, and the battery should be replaced.

On sealed-top batteries that do not have a built-in charge indicator, the state of charge can be determined by checking the battery's base or open circuit voltage with a digital voltmeter or multimeter. This is done by touching the meter leads to the positive and negative battery terminals while the ignition key is off.
A reading of 12.66 volts indicates a fully charged battery; 12.45 volts is 75% charged, 12.24 volts is 50% charged, and 12.06 volts is 25% charged.

In recharging the battery do not attempt to recharge a battery with low (or frozen) electrolyte! Doing so risks blowing up the battery if the hydrogen gas inside is ignited by a spark.
Your charging system should be capable of recharging the battery if it is not fully discharged. Thirty minutes or so of normal driving should be enough.
If your battery is completely dead or extremely low, it should be recharged with a fast or slow charger. This will reduce the risk of overtaxing and damaging your vehicle's charging system. One or both battery cables should be disconnected from the battery prior to charging it with a charger. This will eliminate any risk of damage to your vehicle's electrical system or its onboard electronics.

Take care and good luck

NB: Your alternator might not also be charging the battery while the car is on, so try to check the alternator.

Alternators are pretty rugged, but can succumb to excessive heat and overwork. They can also be damaged by sudden voltage overloads (as when someone attempts to jump start a dead battery and crosses up the jumper connections or if someone disconnects a battery cable from the battery while the engine is running).
Sometimes alternators can partially fail. In the back of every alternator is a "diode trio" that converts the alternators AC (alternating current) output to DC (direct current). If one or more of these diodes fail, the alternator's amperage output will be reduced. It may continue to produce some current, but not enough to keep the battery fully charged -- especially at idle or low speed.
Most service facilities have test equipment that can identify these kind of problems. So if you suspect a weak alternator, you should have it tested to see if it needs replacing.
Most service facilities do not repair or rebuild alternators because it's too time consuming and requires special parts. Most will replace your old unit with a new or remanufactured unit. Your old alternator is usually traded in or exchanged for a credit (so it can be remanufactured and sold to someone else).

What does it mean when the light at the top of the remote is red instead of green?


The red indicates low battery. The batteries are estimated to last around 2 years at that point or later the battery will weaken and the red light will show up more often. In some rare cases the red light will not go away even with a fully charged new battery, in that case there may be something wrong with the charging circuit inside the remote that gives feedback on the battery's charge. You can either live with a false reading of the battery level and charge the remote nightly OR you can send it to RTI for a repair.

Battery keeps dying


Most likely the charging circuitry has failed. When you fully charge the new battery what does the battery meter read on the camera? Your two options no matter what the case are repair vs. replacement. If you need further assistance let me know.

WILL NOT CHARGE BATTERY


Do you get steady or blinking CHARGE indicator light on the laptop somewhere? If not, the WALL-Wart/External power supply or its connection is bad. This can be due to stressed wiring, bent DC socket or cold-solder joint where it mounts to the motherboard (inside case)... or bad outlet (house socket) or a blown PS

IBM Thinkpad T23 Won't Start


do you have a hard drive install??
laptop need a hard drive to start up. the one time start up you see before is just a accident.
as far as battery not charge, that is the porblem you run into, when you get laptop from ebay (taking chance).
you also need to download all of the drivers from IBM for the laptop.

IBM T23 Thinkpad battery does not charge


If you have some electronic skills and are not afraid to open up your laptop then I might have a solution for this. It could be a known problem in T23 where one component is loosen from the mainboard and in that case it can be fixed with a soldering iron. Other possible cause is blown fuses. But to confirm this you have to remove the keyboard and do the check.
