It is estimated that you will have a few days to recharge your battery if the battery is exhausted.

Hp nx6110 laptop is power lock what is unlockng process


Disconnected the RTC battery will unlock your system. See the steps below.

The more important it is to protect on's data by a DriveLock (which makes the HDD usuable when the password is not available).

Procedure to remove password
(following CPQ MSGs)

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.

Warning: All settings are set back to factory standard.
You'll have to enter a correct date/time and change the settings to your needs.

Note: Pls strictly keep to the sequence.
Re-starting with the main battery and or RTC-battery inserted will spoil the job.

Nc6000 multibay battery does not recharge


Perhaps remove the multi-bay battery, and let main battery charge all the way. Then reattach multi-bay battery, and see if it's recognized.
(Will charge)

That is AC adapter (Charger) removed, then remove multi-bay battery.
Plug AC adapter back into laptop, THEN plug AC adapter into power.

[You do Not want to unplug an AC adapter from a laptop, with the AC adapter plugged into power. Could be a power surge/voltage spike. Unplug AC adapter from power, when plugging into laptop, or unplugging from laptop ]

Main battery charged, unplug power to AC adapter, unplug AC adapter from laptop. Plug multi-bay battery in, then AC adapter.
(Then plug AC adapter into power)

Computer was on battery power, warning mess came on pluged in ac right after loss battery power now i get nothing. ac power light is on,but thats all


Remove the main battery from the laptop and plug the power adapter back in, if it powers up the battery needs to be replaced. It is not uncommon to see the battery load down the laptop when it becomes exhausted, if there is no change have the computer checked out.

I have dell c840. Suddenly only the left most light of the three lights gets orange when power is switched on and then there is no activity and screen remains blank. Bty light when plugged in also remain...


hello

shut down computer - unplug power cord from laptop - remove the battery from laptop - plug Ac adapter into computer and Ac outlet (wall)
turn on computer
if computer does not turn on, replace the AC adapter and cord - then place battery back into computer
plug in new Ac adapter and cord - recharge battery - if orange light stays on after 4-6 hours of charging battery, you need new battery as well - replace battery, charge it up and it should be fine

if you have attempted these steps before and no change occurs, then you may have issue with power connection in computer - locate a service centre to replace power connection on computer

I pluged in the power supply and nothing is happening. The small yellow batery icon came on near the screen and nothing else is happening


Hi,

Remove the mains power lead and then take out the battery. Hold down the on/off button for 30 seconds to dispel any residual power.

Plug in just the mains lead (AC adapter) and see if the machine will boot on mains power only. If it does let it boot up and then shut it down again. Remove AC and reinsert the battery, plug in AC power again and see if it will boot with the battery in.

If it boots up the problem is sorted, if not then there is a problem with battery so you would have to use it on AC only until you find a replacement battery.

Please post back if need anymore help.


Good luck and regards.

When UPS is shut down the lights go out on front pannel but power remains on plugs. It is coming from the AC side not the battery.


The UPS has a fauly/problem.
If your UPS is approx. 600VA, then it is not a true UPS unit but a switch over type. When the mains power fails the UPS switches over to the battery and inverter in milli-secs to provide mains power.
If you turn off the mains supply and shut down your UPS, but you are still getting mains power, then there is a fault with the switch over circuit.
You need to get this unit serviced.

MY COPIER SAYS "MAKING SPACE IN MEMORY" HOW DO I CLEAR THE MEMORY?


If the machine remains without power for a
specific period of time (about 2 hr or more)
while an image exists in its memory, the
power of the vanadium lithium secondary
battery (BAT2) will become exhausted. A
report will automatically be generated when
the machine is turned on.
or
When the jumper plug (JP1) is removed, all data in
control memory will be lost. Therefore, do not
disconnect the jumper plug (JP1). The data stored in
the SRAM is as follows:
- user data (data indicating user mode settings)
- service mode deta (data indicating service mode
settings)
- control data (communications control record of most
recent 20 communications, system dump record)

IPaq rx3115 working like PC not Pocket PC, need to plugin always


You need to purchase a new removable battery for your RX
The removable batts usually only last about a year (like cell phone batteries).
Although it is showing 100% charge, the battery is not storing enough power to run the ipaq

The rx series uses 2 batteries, one is the removable one u can see/access when u remove the back cover. The other batt is a small round batt which stores the basic info for your system (so you don't lose your data when u swap out the removable battery).

This small (backup) batt is similar to the cmos battery on a laptop or pc.
You cannot easily replace this, as the unit needs to be disassembled to access this batt.
If you are tech-y (and brave), the replacement button batteries are sold on ebay for $9-12

Normally, if your removable batt is bad, you could still use your unit plugged in, and could
remove from AC power without losing data. Not the case if your replaceable batt is exhausted.
When both batteries are bad, you lose everything when u remove unit from AC power.

My workaround without having to disassemble unit:
Purchase and fully charge new removable batt (They have huge capacity ones available for like $15 - better than the original !).
Load up all your programs & settings the way you like.
Perform full backup to SD card (& also on PC via active sync - to be safe)
Now the only time you should lose your data (like hard reset) is if you allow the battery
to completely drain, in which case you can restore your backup.
If you purchase 2 removable batts, you can easily swapout without losing data if you
use the usb charge cable & leave ipaq plugged in while you change battery

Hope this helps

Main Battery Power


It cannot switched the batteries. The backup one is a small internal battery just to keep the CMOS with data. That's it.

If you main battery is not charging or when unplugged won't power on, the is likely the main battery is defective, or the charging circuitry of it is failing.
