Nx6110 laptop ac power broken

The gold stem that is inside of the ac power hole on the laptop came out with the ac power plug when I pulled it out.

The reason I pulled it out is the computer just shut down all of a sudden and I couldn't figure out why. How do I attach back the (male) gold stem. Tried to put it back in the slot but it wont stay in...

Thanks for the help

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.

I have a advent 7201.it will not come on on its own and it will not come on when the charger is plugged in.the green light is on on the charger but no power on the laptop.could it be the battery or th


Use a multimeter.

An economical unit can be purchased for as little as $8 to $12.
Available in a multitude of stores. An auto parts store is but one example.
Analog or digital is fine.

The Red probe lead is the Positive lead. Plug it into the hole with the red circle, on the multimeter.

The Black probe lead is the Negative lead. Plug it into the hole circled with a black ring., on the multimeter.

The center knob is the Function knob.
Set it to DC Voltage.
If just a symbol is shown, set it to the dotted line over a solid line symbol.

If there is more than one DC Voltage scale, set it to the 0 - 50 Volt scale.

The plug of the AC adapter (Charger) that plugs into the laptop, has a center hole, and an outside cylindrical metal shell.

The center hole is Positive.
The outer cylindrical metal shell is Negative.

Positive probe lead to the center hole, then touch the Negative probe leads to the cylindrical metal shell.

You should be reading 19 Volts, or VERY close to it.

Also have an assistant gently wiggle this cable, while you are testing.
Have them wiggle the power cable TO AC adapter, also.

An intermittent reading indicates a broken wire, or wires. Discard AC adapter, obtain a good one.

http://www.thelaptoppowersupplyshop.co.uk/advent-7021

The port on the laptop that the AC adapter (Charger) plugs into, is the DC Power Jack.

AC adapter checks out it's on to the DC Power Jack.
Post in a Comment if you wish to go on with the diagnosis.

Total Power Failure When Using the AC Adapter


1) Check the AC adapter. Use a multimeter set to DC Voltage, (Symbol is a dotted line over a solid line)

You aren't checking for voltage output, so much, as you are checking for an intermittent break.

AC adapter plugged into power, and probe leads of the multimeter touching the plug of the AC adapter going to the laptop, have an assistant gently wiggle;

1) First the power cord going to the AC adapter.
2) Then the cable from the AC adapter TO the laptop.

If you get an intermittent reading on the multimeter, you have a broken wire in the AC adapter cable, or power cord.

2) If the AC adapter shows VERY close, to the voltage it's supposed to be putting out, AND there is no intermittent break, go to the DC Power Jack.

[ A economical multimeter can be purchased for around $8 to $12.
Available in a multitude of stores. An auto parts store is but one example.

Analog, (Meter with needle), or digital is fine.

Multimeter's vary in style.
It will have a Function knob in the center. This is turned to DC Voltage.
As stated, if just a symbol, it is a dotted line over a solid line.
IF, there is more than one DC Voltage scale, set it to the 0 - 50 Volt scale.

The red probe lead is the Positive lead.
The black probe lead is the Negative probe lead.
You are testing DC Voltage. There is a Positive, and a Negative.

The plug of the AC adapter, that plugs into the DC Power Jack on the laptop, will have a Positive connection, and a Negative connection.

Plugs vary. The most common is a plug with a center hole, and a surrounding metal cylindrical shell.

The Center hole is Positive.
The outer cylindrical metal shell is Negative.

Need more advice post in a Comment ]

Depending on what laptop we are discussing here, the DC Power Jack can be soldered directly to the motherboard, OR it has a cable attached to it, and the cable plugs into the motherboard.
(DC Power Harness)

IF, it is the solder to the motherboard type, it has prongs, or pins, that come out of the bottom of the DC Power Jack, and goes through the motherboard. Then the prongs, or pins, are soldered to the motherboard.

With this style, if the DC Power Jack is bumped, the solder joints of those pins, may be cracked. Makes a bad contact.

Could also be bad enough to make a Short. (Laptop turns off when AC adapter is plugged in)

The DC Power Jack itself may be in bad repair.
Using as an example of the style that has a Center hole, and a surrounding cylindrical metal shell, (Inside), if the two parts touch, you can have a Short.

The diagnoses is to start with removing ALL power, AC adapter ('Natch), and Battery.
See with a small wooden object, if you can gently wiggle the DC Power Jack.

ANY perceptible movement means a bad DC Power Jack.
You will also have to partially disassemble the laptop, to check the DC Power Jack solder connections, to the motherboard.

3) DC Power Jack checks out, the problem has gone serious.

Mounted to the laptop motherboard is a power controller chipset.
It is a power MOSFET,

[ Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_Circuit

The power MOSFET is a type of I.C.,

http://en.wikipedia.org/wiki/Power_MOSFET ]

If you open the laptop, and view the motherboard, this problem will be readily apparent. This chipset usually burns, and turns blackish.

Problem is when it does, the manufacturer's ID numbers are hard to read, in order to obtain a replacement ]

This is one power controller chipset that is used in a LOT of laptops,

https://docs.google.com/viewer?a=v&q=cache:oER5NNz8cwcJ:www.fairchildsemi.com/ds/FD/FDS6675BZ.pdf+Fairchild+FDS6675BZ&hl=en&pid=bl&srcid=ADGEEShOhWPjm_M-ROHme4iEMrztCTOd-28jNiy1hVLQQh_VOyv8zcXEVDB_iTQA6MuZO88UmRkDgjyW9j4CP2aIJ-4DS-h6JNM3lvxldeApQeecmz_DADCw1s7tmNLxfPknqX14SZP6&sig=AHIEtbS_rYUAeo_8rB9YHkW05ZjLqeH4Jg

This is another one,

http://html.alldatasheet.com/html-pdf/85156/VISHAY/SI4925BDY/183/1/SI4925BDY.html

Both of these chipsets uses a D2PAK surface mount.
The leads are bent into a J shape. ( J Lead)

The 'foot' of the J lead is soldered to a copper pad on the motherboard.
(Copper Pad has a thin gold plating on it)

Simple de-soldering/soldering techniques, are used to Remove the chipset.
HOWEVER, use a Heatsink on EACH J lead, when soldering the new chipset in.

(The power MOSFET has transistor/s inside )

OR, replace the motherboard.

Compaq nx6110 PC Laptops: When i turn it on the lights flashes then goes off...


Which light flashes? If it is the battery light then perhaps your battery is empty?
When plugged into your PSU does the power light turn on? If not your PSU may have broken or the plugs fuse may have blown.
Other potential causes could be your RAM, CPU or even your system board. Check the RAM is correctly seated, if two modules are installed try removing one.

Hello, I am having problems with my Compaq nx6110 laptop not charging. It is not the battery, as I replaced it at the end of December. The problem seems to be that the charge isn't reaching the battery,...


If you remove the battery, does the AC Adapter power the computer? Does the laptop have a barrel type power connector? I have replaced several power connectors for broken center pin. Does wiggling the power connector affect the charging light?

My acer laptop wont get any power when i plug it in the ac outlet. and the inside of the computer where the ac adapter plugs in is a little loose also.


The inside connection may be broken which may or may not be repairable. Check to make sure your power adapter is supplying power to the laptop. Use a volt meter to measure.

Hi!

Your issue with your portable seems to be an ac adpter problem based from my experience.

After replacing ac adpter and issue is still present, the problem is with the power supply and/or motherboard which needs to be replaced.

You may need to call your technician for servicing or send it to your OEM's service depot.


Thanks and good luck! =)
