  1. Click on Start
  2. Open Control Panel
  3. Click on Date and Time
  4. Click on Time Zone
  5. Select the right time zone by clicking the arrow below
  6. After selecting time zone don't forget to click "automatically adjust...."
  7. Click OK

Check CMOS Battery

There is battery named CMOS on the motherboard, if this battery becomes dead PC loses its date and time settings. Problem in battery may result in this issue. Replacing the battery with a new one is the best solution to fix the problem.

Install Windows Update

Some of the Windows updates also contain a patch to fix clock keeps resetting. To download and install latest Windows updates follow the steps below:

  1. Click on Start and open Control Panel
  2. Locate and click on Windows Update
  3. In the right panel click on Check for Updates
  4. Install the Updates
  5. Restart your computer

Repair Windows Registry

Mostly PC problems occur due to corrupt Windows registry. To fix clock keeps resetting problem you are required to fix registry error. You will need a good System Utilities program that includes a Registry Cleaning feature. Registry Cleaner deeply scans registry problems and fixes them instantly.

SOURCE: i bought my new Sony Vaio VPCEH last 2 weeks ago,. dual core, 2.3ghz, 4gb ram.. what i wondered is why my cpu almost overload all the time even i just use firefox, or explorer (opening folders ) or so

The CPU is runnimg with a useage of 45-60% as soon as the laptop has booted up because Kapersky is upgrading the virus definition file and is running a virus check on the files stored on the hard disk. When Kapersky has finished these tasks then you will see a drop in CPU useage.
NOTE as you install more programs and as your data files increase so will it take longer for Kapersky to carry out the virus scan.

SOURCE: sony vaio pcg 7184l system does not power on

That's why I always tell people;

1) Install the Battery
2) Connect the AC adapter (Charger)
3) THEN connect the AC adapter to power.

AC adapter disconnected, remove the Battery.
Press the Power On button in, and hold it in for a count of 10 seconds.
(And I mean 10. Count, 1001,..1002,..1003,..1004, etc)
Let go of the Power On button.

Do this procedure 2 more times.
What we are doing here is clearing CMOS Error Codes, resetting BIOS setup back to the factory default settings; and resetting sensor values in the power circuit section of the motherboard.

Now reinstall the Battery. Reinstall the AC adapter. Plug back into power. WAIT 1 minute, turn the laptop on.

Still no?
Suggest we have a problem Houston.

Power MOSFET's in the power circuit section of the motherboard, or may be just a bad Power On switch, now.

The Sony VAIO PCG-7184L is also the VAIO VGN-NW235F

Use an ESD wrist strap, and have it's alligator clip attached to a good ground source. Average cost is around $3 to $6.
One example.

http://www.radioshack.com/product/index.jsp?productId=2103245

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
I feel an Anti-Static Mat is unwarranted.

You can also set a large metal serving tray (Unpainted), on the table you're working on, and connect to it.
Or a large metal knickknack. (Unpainted)

Use a multi-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws.
Advise DO NOT mix them up.

Look at the motherboard where the DC Power Jack is mounted.
(The DC Power Jack is where the AC adapter plugs into, on the laptop)
You'll see Power MOSFET's, and MLCC's surrounding them.

[Multi-Layer Ceramic Capacitor. They are also SMD/SMT, as the Power MOSFET's are.
Surface Mount Device/ Surface Mount Technology ]

This is an example using HP Pavilion dv6000 series, and Pavilion dv9000 series, of Notebook PC's,

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

Uses a Fairchild Semiconductor International - FDS6679 - Power MOSFET, and an Alpha & Omega Limited - AO4407 - Power MOSFET.

Looking at the second photo down with the AO4407 circled in Yellow;
Look at the rectangular smaller object to the immediate Right; that has the dark wide band across the middle of it.
This is an MLCC.

There is one above it, one above that one to the Top; one to the right of the top one; and one to the right of it.
See if any of these are burned/blistered also.

Or it might be worse, Clifton,

May be time for motherboard replacement.

[More examples of procuring Power MOSFET's, MLCC's, and other related electronic components; plus procedures for de-soldering/soldering SMD/SMT components,

(Use a low wattage soldering iron (25 Watts?), Rosin core solder, rosin flux paste, and flux paste brush; instead of a Soldering Station.

Use Isopropyl Alcohol, and an old toothbrush to clean the motherboard, after removing components, to remove the residue left behind.

CAUTION!!
Isopropyl alcohol (Rubbing alcohol), is EXTREMELY FLAMMABLE.
Use in a WELL ventilated area with NO sparks or flames present )

How to make the led brighter


To fix the dim brightness level, remove the battery and pull the plug out of the mains power. Leave it disconnected for at least 5 minutes then plug it back into mains power. You should find the brightness has retuned to normal. I have 3 of these Clock Radios and the picture attached shows the comparison between dim and normal. For some unknown reason they intermittently decide to dim themselves. This may be why Sony included a dimmer in the next model up ICF-C318. Anyway I hope this helps

Clock Losing Its Memory


Our oven clock does the same thing every time the power blips, but we live way out in the boonies and expect occasional problems. Do your lights blink too? Check with your neighbors to see if they have power problems. If this is a chronic situation, contact your power company to see if they can repair the situation.

CMOS Battery


you want to be looking for the rtc(real time clock) which is a little unit not much bigger than ur thumb nail.next to it youll find the battery(sometimes heat sealed with plastic.)if you remove this battery for about 5 mins then replace it or in ur case maybe renew it this will reset bios to factory(also method for bypass passwords as every thing is reset)
you might also wanna check ur video card.(connections and dust)
