Hp touchsmart 300


From the User Guide at... http://h10025.www1.hp.com/ewfrf/wc/manualCategory?cc=us&dlc=en&lc=en&product=4174137&

The wireless keyboard and mouse are pre-synchronized, for your convenience, to work with your

HP TouchSmart PC. The keyboard and mouse should work immediately after you pull the battery tabs to

activate the preinstalled batteries, and then turn on the mouse (A).

You may need to manually synchronize the wireless keyboard or mouse if they are not functioning.

To synchronize them:

Make sure the keyboard and mouse are next to the HP TouchSmart PC, within 30 cm (1 foot) and

away from interference from other devices.

Keyboard: Press the Connect button on the bottom of the keyboard (B) for five seconds. The blue

activity LED on the wireless receiver illuminates when the synchronization command has been received

and turns off when synchronization is complete.

Mouse: Press the Connect button on the bottom of the mouse (C) for five seconds. The blue activity

LED on the wireless receiver illuminates when the synchronization command has been received and

turns off when synchronization is complete.

If this does not work, remove and then re-insert the wireless keyboard and mouse receiver from the back of
the computer and then synchronize the keyboard and mouse again.

Green light next to power button stays on - no response from computer, totally frozen for up to 12 hrs, then green light goes off, computer suddenly comes on for 5-10 min then freezes again.


Good day sir, hi, You need a thorough check on your PC.
But first try testing the Motherboard, Processor and Memory module.

As this point you need a friend, that knows how to tinker with your PC

Or you may need to do this.

1. memory testing:
Try replacing a new memory ram module on your PC, get the modules out of the memory slot, and let it be tested on another PC. if good,

2. power supply
Test for the power supply box, remove the 20/24 pin power connector from the mainboard and short the green and any black wire, your fan should blow out air.

3. Test for motherboard.
remove all coonections from the motherboard, except the 20/24 pin power connector, and the 12v 4-pin molex power connector, connect the pc speaker or the thumb speaker on the speaker port, connect a keyboard, clear the CMOS, (or remove the battery temporarily), connect the header panel (power switch, reset, power led) place the processor and memory (the tested good one). power on.


You should hear a beep (good) The keyboard will light up the three leds, then a few seconds, the numlock led.

If you hear 1 long and 2 or 3 short beeps, problem with the display section. Reseat any graphics card. test again.

If you hear continous beeps, reseat the memory, if the beeping persist, replace your motherboard.

If you hear nothing? only fan blowing, replace your motherboard.

I can only give you instructions, you need a someone who knows how to service a PC.

Gateway 3200S. will not begin to power up. a green led is on at the top of the mainboard. that is the only indicator of power.


Dear Rythmickarma,
As you said the main power LED seems to be glowing but the system is not powering on... so there are few things to check here:
  1. Remove all other connections apart from Power supply, keyboard, mouse and monitor and see if that makes any difference.
  2. When the computer normally boots up there is a POST check Beep sound from CPU .. do you here any beep?
  3. When you tap on numlock key on your keyboard, do you see numlock LED toggle between ON and OFF state?
  4. Is there any signal on monitor .. When disconnected from the CPU, the monitor should show Self test signal .. does it happen?
  5. Open the chassis and check if you can feel the spinning of Hard drive...
  6. Remove the power supply cord from the back of the computer and press and hold the power button for few seconds .. this would drain the accumulated power from the CPU components .. now reconnect the power supply and see if that makes any difference..
Please try the above steps and let me know. Hope that helps.

Regards,
Srinivas
