Hmmm..sounds like an internal issue, if it's happening on either channel..can you boot up in safe mode(F8) and maybe run a virus scan?

I need administrator password for compaq nx6110


1.) Unplug AC, take out the main battery.

2.) Take out /disconnect the RTC (real time clock) battery for app. half an hour (the period of 5 min as specified in the MSG normally is not long enough).

3.) Plug in the AC adapter (batteries still removed); computer should boot automatically, if not use the power button.

4.) The machine will boot and show the 162-error-msg "system options not set". Use F1 to save the settings.

5.) Shut down the computer and disconnect AC power again.
6.) Re-connect the RTC-battery.
7.) Install the battery pack(s).
8.) Restart the computer.

Laptop power charging stops and laptop later shuts down and no charging


First you should figure out what caused this problem. Here below are some possible cause:

AC Adapter Problems
If the AC adapter is not working properly, then the charging won't occur at all. An AC adapter, with lower than required voltage settings, will not be able to charge the battery. See to it that the AC adapter matches the laptop battery's requisite settings. A loose wire or internal breakdown, may render an AC adapter useless. Changing the adapter all together might solve your problem.

Power Management Software Problem
Sometimes, the problem is merely with the power management software. This is the classic case, when the laptop charges when switched off, but doesn't when the computer has booted. The software may have gotten corrupted which must be causing the problem. In such a case, go to the device manager section and uninstall the power management software. In case of Windows XP, uninstall 'Microsoft ACPI Compliant Control Method Battery listing' from the device manger section. Take care that you do not install any other AC adapter driver software. Then go for a 'hardware scan', which will automatically identify the battery and reinstall the latest version of the drivers again. That will restore the charging facility of your laptop.
Internal Charging Circuitry Problem
If neither the AC adapter, nor the power management software has a problem, then problem can be with the internal charging circuitry of the laptop. In this case, there is little you can do, other than send the laptop to the manufacturer's service center.
Bad Battery
If you have checked for all of the above, one of the main reasons, which could lead to the problem of laptop plugged in but laptop battery not charging is a bad or dead battery. Run a laptop battery test. If your laptop is quite old, this could be one of the most likely reasons. Get the battery checked from the manufacturer and check if it has exceeded its predicted recharge cycle limit. It is important that you get the dead battery replaced immediately with a new one. Laptop battery troubleshooting will solve the problem.

Hope this will help.

Could be the power supply. (Likely built into the power cord). Heat could have been causing it to fail before. Possibly dead now!

My ibm laptop contionusly beeps and says power scource is battery,when i press esc, it boots normally and shuts down in about 15 mins to half an hour


Either:
A. Bad battery
Or
B Bad power supply.

Sounds like the battery isnt charging correctly , the beeping is warning you it is running out of power.

Take the battery out , and boot normally with the ac adapter.

Does it work?

If yes, Get new battery. about 70-90 dollars.

If no. Get new ac adapter. 20-40 dollars.

Sony PCG-F340 keeps shutting down


Old Sony laptops do this when the battery is dead, or the charging system is below required voltage. A battery with a dead cell (which this sounds like) can damage your external PSU and internal battery/power regulator circuit. Remove the battery (shut down and disconnect PSU first). You can run the laptop forever, without the battery, if you cannot find a battery replacement, or do not like the cost. Obviously, though, the laptop will not run at all without the AC/PSU connected when the battery is removed.
