SOURCE: Hp TouchSmart 310 wont start,power light flashes

The LED light has now turned into a diagnostic light. The fault is a bad Power Supply.
Replacing it however, is easier said than done.

I don't know what exact model of the Touchsmart 310 series you have.
(Examples such as TouchSmart 310-1000Z, or 310-1125f, or 310-1155y, etc.)

The TouchSmart 310 series of All-In-One desktop computers, has a battery, and an AC adapter, (Charger), for power.

Test the battery with a multimeter set to DC Voltage.
{Symbol is a dotted line over a solid line. If there is more than one DC Voltage setting, set it to 0 - 50 Volts }

Should be close to 18.5 Volts (DC)

Battery is low?
Check the AC adapter (Charger)

The middle metal cylinder of the plug that goes into the computer, is Positive.
The outside metal shell which surrounds it, is Negative.
Again, 18.5 Volts (DC)

Check both then post back in a Comment.

http://h10025.www1.hp.com/ewfrf/wc/product?product=3672542&lc=en&cc=us&dlc=en&lang=en&cc=us

1) Hold the Power On button in, and turn the computer off. (10 seconds)
Unplug the computer from power.

Press, and hold the Power On button for 10 seconds. Let go.
Do this same procedure two more times. Keep performing until the Power On LED quits lighting up.

Plug the computer back into power. WAIT 1 minute, turn the computer on.

Just trying to see if clearing CMOS Error Codes may fix the problem.

2) More than likely the power brownout, or utility company working on the line, has burned out the power supply.

(No. The nimrod journeyman lineman/men, are not responsible for damage to your electrical appliances. !O_O!
Nor is the utility company )

The power supply is a combination, of the AC adapter that you plug into the all-in-one touchscreen desktop computer, and the power section of the motherboard.

AC adapter:
Use a multimeter, and check the voltage output of the AC adapter;

An economical multimeter can be purchased for as little as $5 to $12, here in the States.
Available in a multitude of stores. An auto parts store is but one example. Sometimes the checkout aisle racks of major discount stores have them. Places like Radio Shack have them.

For an economical model it can be an analog model, or digital.
The Positive (Red) probe lead is plugged into the DC port on the multimeter. (Red hole that has DC listed by it as one of the options)

The Negative (Black) probe lead is plugged into the hole on the multimeter, that is Black. (Or has a Minus - sign next to it)

The Function knob is turned to DC Voltage. If just a symbol, the symbol is a dotted line over a solid line.
If there is more than one DC Voltage scale, turn it to the 0-50 volt DC scale.

The plug end of the AC adapter that plugs into the all-in-one touchscreen, has a Center Hole, and a cylindrical metal shell on the outside.

The center hole is the Positive connection, and where the Positive (Red) probe lead goes.
The cylindrical outside metal shell is the Negative connection, and where the Negative (Black) probe lead is touched to.

AC adapter plugged into power, test the AC adapter.
You should be reading 18.5 Volts (DC), or a little higher.

http://www.amazon.com/HP-Replacement-Adapter-TouchSmart-600-1000/dp/B006HNVRO2/ref=sr_1_5?ie=UTF8&qid=1350927682&sr=8-5&keywords=hp+touchsmart+ac+adapter

[ Also although it isn't directly connected to this diagnoses, I feel it it would also be good thing, to check the cables while you're at it.

While testing with the multimeter have an assistant, gently wiggle the cable from AC adapter TO computer, and the power cord TO AC adapter.
A fluctuation in the reading on the multimeter indicates broken wires in either the cable, or the power cord ]

AC adapter checks out?
Problem is with Electrolytic Capacitors on the motherboard, and/or Power MOSFETs.

NOTE*
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.

With this style of desktop computer, you CANNOT just touch the metal frame of the open computer, and relieve your body of Static.
You need to buy, and wear an ESD wrist strap, and have it's alligator clip attached to a good ground source.

Electro Static Discharge. Average cost is around $3 to $6. Here is one example,

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

I connect the alligator clip to an unpainted surface, of the metal frame of an open, empty desktop computer case.

(I feel an Anti-Static Mat is unwarranted. I do not want my wrist connected to the utility companies ground source. May be a quick storm blo-w in with lightning, or some journeyman lineman may scre-w something up when doing line construction. Yes. I hold a journeyman's license, lol!)

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

Open the covers,

Visual identification of 'bad caps',

http://www.capacitorlab.com/visible-failures/index.htm

Check to see if any of the Power MOSFETs are blackened, or blistered. Average example of a Power MOSFET,

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

Apparently the same motherboard, is used in an HP TouchSmart IQ770 also,

http://www.ebay.com/itm/HP-Touchsmart-iQ770-5188-6259-Motherboard-Asus-A8SN-CF-w-2GB-RAM-/261110745455?pt=Motherboards&hash=item3ccb69c96f

Also check to see if there is any apparent damage, to other electronic components on the motherboard

I can guide you in replacing Electrolytic Capacitors.
(They are Radial Aluminum Electrolytic Capacitors)

This guidance is for replacing Power MOSFETs, or other SMD's.
(Surface Mount Device),

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

http://www.youtube.com/watch?v=5uiroWBkdFY&feature=fvwrel

( You can use a low wattage soldering iron { 25 Watts }, and that beveled tip also. Do not need a Soldering Station.
DO NEED rosin flux paste, .030 Rosin solder, Desoldering Braid, (Solder Wick), damp sponge for cleaning soldering iron tip, old toothbrush, and a steady hand )

Just an example of a Fairchild Semiconductor - FDS6679 - Power MOSFET, one place to get it from, and average cost,

One Dollar and one Penny, USD.

Same place for Radial Aluminum Electrolytic Capacitors.

How to change the cmos battery on a touchsmart 310 1020


  • Study the Upgrade guide from HP before starting so you can remove the battery if you drop it in the machine by accident. As of the time of writing, there is no dedicated guide on how to change this battery the long way. Because of this I am going to recommend reading the HP upgrade manual for now. Once you have the back removed, remove the screws from the motherboard EMI shield. These are all the same length, and can be sorted in one pile. Find the battery and remove it from the system once you find it.
  • You should ideally use ESD safe tweezers for this procedure. You are after all, poking around at the system's internals semi blindly. It doesn't hurt to be sure.

    HP TouchSmart 310-1125f display is black


    Hearing fans and hard drive spin up doesn't necessarily mean system is working - just without video. If you heard a POST beep or the Windows Startup sound that would be different - and good. Is there any video on the screen at all, even just a blinking cursor in upper left of display? If not, your problem is probably hardware such as ram or motherboard. If this system has a VGA or HDMI output to connect to another monitor or TV would be a good check, but AIO system usually don't have that option. Other than that, and this is a shot in the dark: Ensure the system is off, disconnect the power plug, and hold the power button in for 30 sec for a power reset. Then plug in system and try powering it up again. If no go, you may have a hardware problem and will need a PC Tech. Hopefully it is just loose ram.

    My hp touchsmart 300-1223 fan runs but nothing else works


    Hi Howard -
    A few questions for you - When you press the Power Button, do you see and flashing LEDs? If so, which LEDs and how many times do they flash?

    You can try unplugging the system from any power, hold down the power button for 30 seconds (drains all flea power) and plug it in and try. Basic move, but I've had it work several times before.

    Let me know -
