No Power


Your laptop's power jack may be broken, which is why your laptop doesn't charge your battery at all, which is why it won't turn on now. I would take a look to make sure that the power supply is good, the battery is good, and then see if the power LED is even coming on when you plug the laptop to a power source.

My hp compaq tc4200 wont turn on.if i plug power cable it shows charging after few seconds it wont charge i removed battery but the problem still


Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test your compaq tc4200 power supply with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

Acer 5570z no lites will not power on


Knowing that the new AC adapter (power supply), is putting out 19 to 20.5 Volts (DC), then the problem needs to be diagnosed further.

[ AC adapter is checked with multimeter. Function knob set to DC Voltage. (Dotted line over a solid line) Center hole in plug for AC adapter, that goes to laptop, is the Positive connection. (Red probe lead of multimeter touches)

Outside metal shell of plug is Negative. (Black probe lead of multimeter touches) An economical multimeter can be purchased for around $5 to $12. A multitude of stores carry them. An auto parts store is but one example. Analog, or digital is fine]

The jack in the laptop, that the plug for the AC adapter (power supply), plugs into, is the DC Power Jack.

With many DC Power Jack's, the jack is soldered directly to the motherboard.

Not so with the Acer Aspire 5570z series of Notebook PC's.
The DC Power Jack is connected to a cable of wires, which in turn is connected to the motherboard.
DC Power Jack Harness.

Replacement, is disassembling the laptop down to the DC Power Jack harness, unplugging it's cable's connector, and plugging in a new DC Power Jack harness.

The Bottom Case holds the DC Power Jack in place. (There is a slot in the side of the case it sits in)

Battery removed use an object to see if you can wiggle the Center Pin around. (Pencil? Or C-a-r-e-f-u-l-l-y, a flat tip Jewelers screwdriver? )

Also see if the rest of the DC Power jack, that you can see, will move around.

A-N-Y perceptible movement means a problem with the DC Power Jack.
It would also be best to go further, disassemble down, and remove the DC Power Jack Harness, even if no movement is found.

Perform a Continuity Check with a multimeter. Check each wire in the harness to make sure they are good.


No problem found with the DC Power Jack?
Then the problem is a power sensor chipset, or chipsets, on the motherboard. This part of the laptop IS the power supply.
The AC adapter is just part of the power supply.

If this is found to be the problem, motherboard replacement is the viable solution.

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

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

The power supply (Sensor chipset/s) senses whether the Battery needs a charge. Full or just trickle. It also senses when the laptop is to just run off of the AC adapter, and not the Battery, or Battery, and not the AC adapter.
{Plus a few other functions}

Here is the link to the Service Manual, (Free), for the Acer Aspire 5570 series of Notebook PC's,

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acer

Go to the second Aspire heading. The one that begins with Aspire 1200
Go down to the 8th line, and across to 5570. Left-click on 5570
This is a PDF file. May take up to 30 seconds after you click, before the first page comes up.

1) Use an ESD wrist strap. Connect it's alligator clip to a good ground source. (Electro Static Discharge. I connect to an unpainted surface, of the metal frame of an open empty desktop computer case)

Average cost is around $3 to $6.
One example of an ESD wrist strap,

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

2) Use a multi-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s come out of.
If no multi-compartment container is available, substitute with a clean egg carton.
Label each egg holder.
(Or double-sided tape, and label the tape)

There are screws which look VERY similar to others.
Do NOT mix them up.

3) Make a record as you disassemble. Make notes, drawings, and use a digital camera, or video cam, with good lighting.

Nice to have a record to refer back to, in case you are interrupted.
Also nice to have a Personal record made by you, along with the Service Manual

Got a machine but it keeps switching off after few minutes could it be power switch on front if so where can i get one


It isnt the power switch, it's the power supply itself. You need to get a new one from bestbuy.com, Tigerdirect.com or Geeks.com.

Emachines are notorious for their bad power supplies, and they usually burn out the motherboard when they die. Stop pushing that button and get a new Power supply before your board messes up.

The drum machine goes on and off, and I think the problem is at the connection from the power cord into the SR16. I think I need a new power cord.Or is there an internal problem at the connection?


It sounds like the adapter jack in the Alesis has a bad solder joint to the circuit board .This is a fairly common problem with all modules that have external power supplies and is an easy fix if you feel confident and are good at soldering.

Emachines M2350 laptop- no power


It's one of two issues. 1 - power supply. 2 - the power management chip on the motherboard. Since the power supply is the lesser of the two, try a new supply first. If that doesn't do the trick then it's the pm chip and the motherboard will need to be replaced.
*NOTE* The power management chip recognizes the type of power being used and allows the computer to switch between AC and battery power, it also allows the unit to charge the battery.
