Question about IBM ThinkPad 600E 2645 Notebook

1 Answer

Won't charge Battery is OK in another machine, external charger works on another machine. Bios battery is OK. When I insert the power lead the display just flickers slightly. In the power meter diagnostic, the battery is not being charged. There is no green or amber l.e.d. display. I assume the internal charging circuitry is faulty - how do I fix it?

No Power on Hp 620 Laptop


If the battery does not charge then the problem is likely the charger.
If you can borrow a charger instead of buying a new one you can find out for sure if the problem is the inside the laptop its self or the charger.
Remove the battery and hold down the standby button for a whole minute to drain any remaining power in the model. replace the battery , attach the new/borrowed charger lead and see if any activity happens ie, sound, lights...ect. This is the first thing someone does in a repair shop and its to diagnose where the issue is comming from.

Blackberry Charger / Sealed Lead Acid Battery


Depends mostly on the voltages and how long you want to wait, but you will have to accept the risk of frying the charger by exceeding the 700mA rating. If the voltage output of the charger is about 10 or 20% higher than the nominal voltage of the battery then it might be OK. If the output of the charger is less than or equal to the battery voltage, then it won't work at all. The smaller the differences in the voltages, the less the risk of overheating the charger, but the longer it will take. If you are in the "sweet spot" it will probably take 6 -8 hours to charge the battery.

Any idea where I get a replacement charger for a Metz60CT4


EBay, if that's what you want. The metz "chargers" are just 7 volt ac transformers - they supply 7 volts to the battery pack which has the actual charging circuit in it. I haven't pulled one apart yet, but I'm guessing they're very rudimentary chargers. Depending on what you're using for a battery you might want to use a modern external smart charger. I use $20 AGM batteries from batteries plus (instead of the $80 metz batteries) and use an external charger from WallMart on them. It's quick, lets me see the current charge state, won't overcharge the battery, and works on my car and boat batteries too.

The low battery light remains on after I changed the battery,


Hello
There are two possibilities for this fault. The first one is with its battery itself. If the battery did not hold current, in otherwords, it has weak, proper charge both in volts and amperes won't hold on it, and when the device draw current from it while it works, voltage drop will occur, and low voltage indication will be displayed.
The second chance is due to the charger circuit inside the radio. If charger circuit do not give proper voltage and current to battery, the battery won't charge to its full capacity.
Check it by replacing it with a new battery [batteries] first. If it helps you it's OK. If not, your radio need service, and its charger circuit must be checked well. OK.

If the phone was totally dead before it refused to charge initially, then the refusal to charge is due to the fact that there was no residual charge left to bring it to a charge, because the battery completely died.
To fix it, kick start the charging process.
Remove the battery, and using a universal charger (desktop charger) charge the battery for say 10 minutes, before re- inserting the battery to the phone and continuing with the normal charging process.
If this does not work out, then problem is with the charging port. It has to be replaced. This can be done by nearby local phone repairers.
Hope it helps?
Success.

Battery is not charging.


Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced. Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

ibm thinkpad does not boot My IBM Thinkpad 600 (Type 2645-310) stops and hang during bootup. What happens is: 1. LED test, then green Power on and orange battery/charging 3. RAM OK (Responds when I take out /put in different amount of RAM and displays correctly. I have 128 + 32 removable, + 32 internal not possible to take out) 2. I can hear fan, CD drive and evt diskette drive. If I use diskette drive the LED wil give 1 blink, if I use CD drive it will give 14 blink. 3. No cursor seen, but this is displayed: Upper left show the amount of RAM present: 196032 KB OK Upper right IBMs logo in blue; IBM Lower left shows "ThinkPad(R)" in large letters and red dot over "i". 4. Then a "rrrrrr" sound from the loudspeakers after a while, this is in fact 28 clicks shortly after each other. Then nothing more happens. Diskette and CD drive is OK (But can not be used because bootup is never finished). I hear CD speed up and then down again but nothing more happens. No effect in booting with bootable diskette or CD, "Live Linux" CD or else. Backup battery OK (3V) and if I take it out I will be asked for correct date and time when Power on. I can then use keyboard or TrackPoint to set date and time, and after that hangup at the usual point. Starting without battery, HDD, CD drive and removable memory sticks makes no difference in symptoms. Pressing and holding F1 before and during poweron and startup (in order to enter BIOS and selftest) has no effect. I could not find help on IBMs home page, but maybe I did not look at the right place. Is somebody able to help me?
