Motherboard voltage solution for hibenation?

I read a post that said the following and would like some input or someone to elaborate and explain how to maybe fix:

"Still sounds like it has gone into hibernation.
But the motherboard may also have a problem ..i.e not sufficienct voltage to bring it out of hibernation"

Could this be the reason why my computer won't come out of hibernation? It makes a noise when I open the lid like it is trying to load and the resume line at the bottom shows but after that it stops making any noise and it stays black. It sounds like it wants to restart and then it stops. If someone can help thanks.

I know that if you remove the hibernate option from power management it won't go into hibernate mode but it use to do well when it went into hibernate mode before, why isn't it working now?

    I fixed my problem! Went to the bios setup page when you restart computer and on the system start up option it was as "boot" and i changed it to "resume". this fixed the problem. I went to hibernate and when I opened the lid of my laptop it brought back what i was working on. I don't even know how that setting got changed in the first place but that did the trick.

Surface resistor


Resistors are not sold by voltage, but by their resistance and the max power they can dissipate. The value is usually printed on it as a three digit number (e.g. 473 means 47000 ohms). If you cannot read anything - you said its blown - youre out of luck. You could find someone else with the same PC and look at his motherboard.
Anyway - if a resistor is blown, there is a reason for it. It is not a bomb, so it wont blow on itself. Probably something in your PC is defective, which causes the resistor to blow.

Tip

How to submit a PC Support question on a forum


Many people use forums for practically everthing in today's world. PC Support happens to be in the top 5 of all forms and here is where my expertise lays. After many years of providing help desk support, the one thing that never seems to end is people posting vague discription of what is wrong with thier pc and get upset when no one can pin-point what is actually wrong with the pc.

Here is an example of a recent problem I was assisting:
"My motherboard does not have video. What is wrong?"

I proceded to ask the model number of the motherboard to which the poster insisted if he knew the model number he would not be asking for help. As great as many of us are with IT, we are not mind readers. We do not have crystal balls that can see every pc on the planet.

Here is a TIP for posting pc support questions on any forum:

  1. Always be as specific as possible when explaining what is wrong with your pc. Being vague only makes your question go unasnwered for the most part.
  2. Always include model numbers, brand, and any information that will make research more precise. PC model, card model or brands. If you do not know the model number most manufacture will put the number on the part or on the back of PCs. (Bottom of notebooks)
  3. If someone response to your request and you feel the answer was not to your liking, do not post mean comments. Again, be specific about your exact problem and repost.
  4. If you do get the correct answer or someone get close, be sure to rate thier response. Even if it is free advice, be thankful for that someone took the time to offer assistance. Many of us have a true passion for IT and enjoy helping others.
  5. If you post a request in a different language, use a software that will translate into English (This is the most widely use language on the planet.)
Keep this tip in mind when you find yourself in need of pc support on any forum on the Internet. Follow these guidlines and you are sure to receive positive feedback and help.

My computer toshiba is not turning on


6 - SUGGESTED SOLUTIONS

I would like you to read that part. Means somewhere, someone, (Staff?), has taken it upon themselves to attach previous solutions, to your posted problem.
(They do it with my previous solutions given, also)

I have seen, "Gary Oldman plays the Bagpipes for You", and, "20 Ways to Knit a Cardigan Sweater"; given as solutions in the computer category. Guess you should feel special, that the suggested solutions even come close.......lol!

A) Nope. It is NOT an obvious 'board issue'. (Reference is to the motherboard)

B) Screen turns Black means a problem with the screen.

Really? (You're going to post that on a the world's largest product support website, and with REAL technical experts in this field looking on? Yeah,...Right!)
(....after all these were done, you must definitely get ride to this mura.......!O_O! What does THAT mean????????????)

Moving on.............

DIAGNOSE

Leave the guessing to those who like to play games.

("I bet aliens in the middle of the night, came down and put a virus in your laptop. If just the LED light on the 'charger' lights up, you know you've been had! Put a tinfoil hat on to protect yourself!")

1) The 'charger' in reference is an AC adapter. It converts the AC electricity from your home, or business; into a low DC Voltage.
(Can also be said as low DC electricity)

The LED light on the AC adapter, is an indication the AC adapter IS receiving power.
NOT an indication the AC adapter is working.

AC adapter is tested with a multimeter. See if it is putting out the correct voltage.
On the AC adapter in a label, is the Input voltage, and the Output voltage.
Example: Input: 100 ~ 240VAC @ 50 ~60Hz
Output: 19VDC @ 4.34A

Means the AC adapter can use AC electricity, that is from 100 to 240 Volts, and either 50 Cycles per Second, or 60 Cycles per Second.
Hz = Hertz. Hertz stands for Cycles per Second

Output is 19 Volts DC, and at 4.34 Amperes
The number to be concerned with here is the 19 Volts (DC)
19 Volts (DC), or VERY close; is what should come out of the cable, that plugs into the laptop.

Also suggest have an assistant gently wiggle the cable, that goes from the AC adapter TO the laptop.
If there is an intermittent reading on the multimeter, this suggests there is a broken wire in that cable.
Same procedure for the power cable TO AC adapter.

Not feasible for you, then take to nearest small computer shop, and have the resident tech check it out. Should only be a couple of bucks.

Tech indicates it's bad, has a new one, or universal one they will sell you? I think I would take my old AC adapter, and leave. May be on the up and up, may not.
If it is said that the AC adapter is bad, and you can buy a universal one almost anywhere; THEN I would tend to believe the person.

AC adapter needs to be working, and correctly. (Proper output voltage)
Charges the Battery, and also can power the laptop by itself.

2) DC Power Jack:
The DC Power Jack is the jack on the laptop (DC_IN), that the AC adapter plugs into.
If there is a problem with this jack, the laptop will not receive power.

There are various styles of DC Power Jacks.
Most common is the style, that has a large Center Pin in the middle.
AC adapter removed, Battery removed; a small object is used to GENTLY see, if the Center Pin can be moved.
ANY perceptible movement of the Center Pin, indicates replace DC Power Jack.

With the older style of laptops, the DC Power Jack is soldered directly to the motherboard.
With the newer style it is not.
The DC Power Jack has wires coming from it, (Cable), and they end in a male plug connector.
It is now referenced as a DC Power Harness.
Much easier to replace, than the old soldered on version.

3) Bad Power On switch.
It's a small carbon button switch, and they do go bad.

4) All of the above checks out, then the problem is the 'board'.
Motherboard.

More specifically small electronic parts on the motherboard, have gone to the 'Great Electronic Parts store in the sky'.
(How's that for technical? lol!)

Usually Power MOSFET's on the motherboard.
Many people then replace the motherboard. Some of us do not.

Using the HP Pavilion dv6000 series, and Pavilion dv9000 series; of Notebook PC's for an example,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

Here we see the Fairchild Semiconductor Industries - FDS6679 - Power MOSFET, and Alpha & Omega Semiconductor LTD - AO4407 - Power MOSFET; is being used.

Both are Obsolete now, but there are cross-reference examples given. FDS6679 cross-reference example,

One dollar and one penny - USD

http://www.youtube.com/watch?v=3NN7UGWYmBY

Price of replacement motherboard? Averages from $50 to $250
Also add labor cost.

HOWEVER, there is more information that I need from you;

1) You indicate, "The screen does not turn on at all. It has no light but the charger light is the only light that turns on."

Meaning ONLY the AC adapter's Power On LED lights up?
No Battery LED light on the laptop?
The small fan is not running?

Makes a BIG difference if the fan is running.

Also post the laptop manufacturer, and model number.
The model number is on the Bottom of the laptop.

Using Compaq and HP laptops as an example, post the Product Number.
This is P/N in the white Service Tag, on the bottom of the laptop.

Cpu upgrade


A) http://www.fixya.com/support/t18040647-cpu_upgrade

B) http://www.fixya.com/support/t18040647-cpu_upgrade

(Last time I looked, this was the world's largest product support website, and there ARE technicians from AROUND the world; on here!!!!!!!! Do we count as an 'IT techie'? ........Lol!)

In all three of your posts, not once has the laptop manufacturer name, and model number been stated.

Processor (CPU) support depends on;

A) What processor socket is on the motherboard?

B) What motherboard chipset does the motherboard use?

C) What is the processor that is installed now?

With these parameters known, THEN you can think about CPU (Processor) upgrade.

1) CPU (Processor) has to FIT, the processor socket being used.
THIS, is also IF the motherboard HAS a processor socket; and is NOT soldered directly to the motherboard.

2) The motherboard chipset supports the Processor (CPU)
It has to be known if the motherboard chipset will support, the CPU (Processor) that you want to upgrade to.

For older computers the motherboard chipset consists of;
A) Northbridge chip
2) Southbridge chip

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

With this technology the Northbridge chip, of the motherboard chipset; is what determines Processor (CPU) support.
Newer technology, such as used per se by the Intel Core i processors, does NOT use a Northbridge chip.

3) Looking at the existing Processor now, you can determine;

A) Voltage Range: What voltage range does the exisiting Processor use now?
Does the upgrade Processor also fall within this Voltage Range?

B) Core technology, and architecture:
Example:
Existing Processor uses the Conroe Core technology, and the 90nm architecture. (NanoMeter)
Does the upgrade Processor also use the same Core technology, and architecture?

If not is there a BIOS upgrade available?
(The motherboard chipset also comes into play again, here)

Enough of this generic prattle.........
Post the laptop manufacturer name, and model number.
Then I, or someone else can give you the facts; and not generic information.

When I try to turn my Toshiba L300 Laptop on the battery light flashes and nothing happens.


Here are things to try:
Check the voltage on your power cord--transformer. I think it should be about 18 volts.
The problem sounds like the battery is discharged. If the voltage you are reading is too low or it's not putting out any voltage at all, then your battery may very well be dead.
Try starting with only the AC power and no battery. If it's a battery problem, this might work.
If everything checks out OK, then it might be the power plug on the motherboard or possibly the motherboard itself that is bad.

My Sony PCG-K10 Laptop is not powering up.


Either the ac adapter is defective or the dc connector on the motherboard is bad. I would test the ac adapter with a volt meter and make sure you are getting voltage through first. If there is power then likely the dc jack and someone will have to solder in a new connector

Sylvania GNET28001SO Meso 8.9" Netbook PC (1.6 GHz Intel Atom


If you are attempting to connect your laptop between 110 and 220 volt power outlets, you may be able to do so already, take a look at your power cord's transformer (brick) and read the input voltage. If you only can use 110 volt AC Input Voltage should read 115VAC. If you can do both, then it should read 110-225VAC. 

If your power brick supports 220, then all you will likely need is a plug adaptor, found at many electronics store. If not, you wil need to stop in at a computer store or an import store and get an international transformer, which are set up to convert many different country plugs and many common voltages.

Good Luck!

HP Pavilion dv1000 AC Adapter Problem?


Dear oliverdog

I am sorry to hear your problems but I hope we can figure this one out. Troubleshooting the AC power is not always easy. Let do the easy stuff first.

Warning: If you are anaware how to handle voltages please dont follow this guideline. It might hurt you or you equipment. Furthermore all parts if covered with warranty can and will be replaced, dont do any repairs as this will void it at some point. (Just to let you know)

If you have a multimeter you can test the actual power supply DC voltage output. When plugged in it should read certain voltages (look at the bottom of the plastics at the power cord (brick) to find the label regarding the voltages. Probably will be saying something like 18V 4.5A) You have to measure this with the multimeter at an appropriate scale (20/40 volts). If you are and not reading any serious +/- fluctuations then the AC input and DC output is fine!

Otherwise start searching for a replacement part.

If the power cord is reading fine the problem cannot always be the DC POWER Jack though. I had an AC Jack problem with a HP ZX5000 earlier this year but this is not always the case.

Please go to the following link (simply press left click/or copy paste to your browser and it will start the download automatically)
It is the complete HP Service Manual on how to troubleshoot and take apart your laptop.

h20000.www2.hp.com/bc/docs/support/SupportManual/c00444244/c00444244.pdf

At page 48 you will find extensive information of step by step info on troubleshooting your power AC up to motherboard problems. It is unfortunately too long to elabore here but it has good info in it.

Anyway, I hoped I have help you! (For anything else please ask me again. I will help!)

Please dont forget to rate this rating if it has helped you.
