Hello ndy3,

It can be because the wire inside the cable is at fault, but the main reason (99% of the time) is because the end or either the laptops power input OR the plug on the dc power cable is not fitting snug enough. This can be fixed by either getting a new dc power cable or by adding a drop (and i do mean drop) of gold or silver (or even solder) to the rim of the laptops input. But you MUST be VERY careful when doing this and make sure that whatever you apply is just coating it. If you do it right then the plug will fit more snug and the problem will be solved.

Hope this helps.

Starts to power up then dies and blue light flashes every 10 seconds


The Asus Eee PC Top ET1602C All-On-One Desktop PC, is set up like a laptop.
All the hardware components are in the main unit.

This includes the Power Board. (Power circuit on the motherboard)
Part of the power circuit is the external AC adapter that you plug in.

Test the output voltage of the AC adapter.
Use a multimeter.
[An inexpensive multimeter can be purchased for as little as $5 to $12. Available in a multitude of stores. An auto parts store is but one example. Some chain stores have them in their checkout aisle racks]

AC adapter plugged into power, not plugged into all-in-one.
The center hole of the plug is the Positive connection.
The cylindrical metal outside shell is the Negative connection.

Function knob to DC Voltage.
[If just a symbol, it is a dotted line over a solid line. Fairly expensive multimeters have an auto detect feature, that senses if it is AC or DC]

Positive (Red) probe lead of multimeter goes to center hole.
Negative (Black) probe lead to outside cylindrical metal shell.
You should read 19 Volts DC.

Also while testing have an assistant gently wiggle the cable from AC adapter to all-in-one, and the power cable to AC adapter.
Fluctuation of reading indicates broken wire/s in that cable, or power cord.
Replace AC adapter if voltage low, or cord/cable damage.
One example from a quick search,

http://www.ebay.com/itm/AC-Adapter-Charger-For-Asus-EeeTop-PC-ET1602C-ET1601-Notebook-Power-Supply-Cord-/390467777452?pt=Laptop_Adapters_Chargers&hash=item5ae9b173ac

AC adapter checks out OK?

The port on the all-in-one that the AC adapter plugs into, is a DC Power Jack.
Suggest use the eraser on a No.2 pencil, and gently see if you can move the center pin around.
If so see if the center pin itself moves, or it seems the entire DC Power Jack moves.

Center pin moves indicates replacement of DC Power Jack.
Entire DC Power Jack moves, MAY just indicate the solder connections for the DC Power Jack to motherboard; may just need to be re-soldered.

DC Power Jack external inspection reveals it is OK?

On the motherboard are electronic components, that deal with the input DC Voltage.
Power MOSFETs, and Ceramic Capacitors to be more specific.

Using an ESD wrist strap, and having it connected to a good ground source, (Average price $3 to $6), the all-in-one is opened up, and electronic components are visually inspected.
Inspected to see if they are blackened, burned, or blistered.

Components are replaced if damaged.
If this is not in your line of expertise, then suggestion is to replace motherboard.

http://www.ebay.com/itm/Asus-27-ET2700-04-ET2700I-All-In-One-Computer-Mother-Board-/130769666691?pt=Desktop_PCs&hash=item1e727ac283

No not your motherboard. Just posted to give you a 'feel' what prices may be like.

Opening Case of All-In-One;
I do not have access to a direct Service Manual, nor have I worked on this model.
Very FEW all-in-one computer manufacturers EVEN post, any such information, and speaking of all; all-in-one computer manufacturers.

The usual route is to remove the Back Stand, then the Back Cover Enclosure.

Look for Philips head screws hidden under paper labels, or thin plastic covers; plus any visible screws when going to remove the Back Stand.
May also be a clip you depress after removing screws.

The Back Cover Enclosure is held on by Philips screws which surround it's outside perimeter.

(Suggest lay the LCD screen side down on a soft cloth, on a table to protect it; and be in the correct position for this procedure )

The Back Cover Enclosure also has Latches around the inside, of it's outside perimeter. These snap into Tabs located on the Front Cover Assembly.

Sometimes it's a lot of fun(?) trying to release these Latches.
A flat tipped screwdriver is used, with EXTREME caution.
The tip is ONLY inserted just so far, and the prying action is used with finesse.

[BETTER tool to use is a Spudger Tool,

http://www.ifixit.com/Tools/Spudger/IF145-002 ]

If the screwdriver does not insert at the point you are trying, it may be because you are at one of the Latches. Move over.

Finesse is used, because the Latches are now brittle from over time, and constant heat from inside the computer.
Even if you use great finesse, do not be surprised if a few of them get broken.
Tech or not, brittle plastic breaks.

It will be OK as the Philips head screws will 'keep everybody together'.

Guides using HP/Compaq All-In-Ones as examples. Glean from them in opening yours, (Ones that are listed as All-in-ones),

http://www.hp.com/hpinfo/globalcitizenship/environment/productdata/disassemblydesktop-pc.html



Note that everything comes off in 'layers'. Metal static shields, optical drive, harddrive, etc.

To replace the LCD screen for example, you have to completely disassemble from the back to the front, then you can access the screws which hold the Display Screen Bezel in place. The Screen Bezel is removed, THEN the LCD screen can be removed from the front.

[Watch me be mistaken with this model, and there IS a way to access the LCD screen from the front, lol! ]

Here are basic examples of components on the motherboard, that you may find to be bad,

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

Average cost of a Fairchild Semiconductor - FDS6679 - Power MOSFET,

http://www.mouser.com/Search/Refine.aspx?Keyword=FDS6679

One dollar, and one penny, USD.

http://www.mouser.com/Passive-Components/Capacitors/Ceramic-Capacitors/Multilayer-Ceramic-Capacitors-MLCC-SMD-SMT/_/N-b2cj?P=1z0wrkrZ1z0vhw8

Dell OptiPlex GX620 no boot sometimes it appears black screen with a cursor blinking


When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.

Don't start my pc


OK, I won't start it. LOL

Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

My gateway laptop note book, will not power up, I have checked the cord, battery etc. Went to turn it on one day and no power? someone mentioned that it over heated?


First of all, take the battery off and try to turn it on with the ac adapter (power cord) connected. If it comes up without the battery then it's your battery.

If it doesn't turn on without the battery and with just the ac adapter, try a different ac adapter. You can find one to try at your local pc shop or electronics store. If it comes up with another ac adapter then all you need to do is purchase an ac adapter at the store or order one online (cheaper).

If it still doesn't come on then it's either your dc jack or your motherboard. Normally if it's just the dc jack it will turn on or attempt to turn on when you wiggle the connecter in the ac adapter connection. If it's your dc jack it's relatively inexpensive to purchase online. The problem comes with having to take apart the laptop, desoldering the old and soldering the new dc jack, and putting the computer back together.

Good luck and let me know if you have any other questions.

My compaq presario 2100 will not start up the power cord plugs in and when you wiggle it it somtimes would work but now wont at all. thank


1. You possibly have a damage ac cord
or you have damaged connecting plug at the PC .
2. try to obtain a new AC cord.
3. Another possibility is the power supply for the PC needs replacement.
4. A PC technician can determine this for you.
Contact Compaq for repair rates because most likely this is a special power supplied system.
