• HP Pavilion tx2500 does not start

  I turn on my HP Pavilion tx2500 and I hear the rotation of the fan, but nothing else happens.  Lights beside the caps lock and especially the blink of keys NumLock (a unique expandable flashing).  According to HP technical support documents that I found online, the expandable single flashing indicates a CPU problem.  My laptop is out of warranty and $400 for send it to HP to fixed it is practically the same price I paid for the laptop 2 years ago.

  Flashing lights mean that the CPU is fried?  And I can do to repair the laptop?

  Thank you

  -Jeff

  Hello Jeff,.

  I'm sorry to say that if he is certainly a fried CPU we are dealing with, service may be the only option.

  However, you can also consider contacting local service centres in this regard.

  Hello

  Try a Hard Reset as follows.

  Shut down the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery, connect the AC adapter and see if the laptop boots.

  If the above doesn't help, see if you can match the sequence of "Flashes" to those shown in the table below.

  

  Kind regards

• Laptop power light blinking and won't turn on

  I have a laptop HP Pavilion 1045DX M6 and I recently tried to plug it into a screen RGB, analog and I saw a spark and the laptop off.

  During this time, I ran the laptop directly from the adapter without battery because I don't really use it.

  If the laptop is turned off and I tried to turn it back on and nothing happened. The charge indicator light turned off even though it was still plugged. I thought that maybe the power adapter does work more or something, but I tested it with a voltmeter and there was still power in.

  So I decided to put the battery in the laptop was able to turn on, and after a while, it an area that I never felt heat it before was really hot and later felt like something was burning.

  But anyway, when it started, the screen resolution was really weak and made a maximum brightness. When the laptop end of initialization, it randomly started to install drivers (such as WLAN rapid storage and intel) and Yes. Sound does not work either. I tried to connect the laptop back and battery does not charge.

  I turned off and took out the battery and tried to run the AC adapter only but the light flickered constantly and when I press on it, the WiFi (F12) button light on for a second then back off the coast. I also hear that high frequency noise I have ever heard before somewhere in the laptop.

  I've done a hard reset with no luck. Any suggestions? Thank you!

  Hi @djstar12 ,

  Welcome to the HP Forums!

  I would like to take a moment and thank you for using the forum, it's a great place to find answers. You have the best experience in the HP forum, I would like to draw your attention to the Guide of the Forums HP first time here? Learn how to publish and more.

  I understand that you have attempted to connect an analog RGB display and you saw a spark. The laptop off and then will not re-start. (the battery has been removed at the time). The light on the adapter was not turned on so you checked the voltage on the adapter and it was fine.

  You tried power turn it on with the battery power and booted up with display dim and started to install the drivers, but you have noticed, it was getting very hot in a specific area. Also, you do not have audio and the battery does not charge.

  Once again, you removed the battery and tried so that it starts with the adapter and the light on the adapter flashes continuously. You also hear the treble and when you tried to activate the wireless, he came for a second and then powered back off.

  The only thing that I can suggest to test the adapter and the equipment.

  Using and testing the power adapter AC

  Test of hardware failures (Windows 7, Vista).

  If you determine that it must be replaced or decide to buy a replacement, you can contact HP technical support for other options.

• HP Pavilion H8 - 1160t Strip annoying red light on front panel, how to disable?

  I bought a new HP Pavilion H8 - 1160t with this red light strip boring on the front panel.  How can I disable this light permanently? Thanks in advance.

  Follow the steps in thislink to remove the front cover and power button/light. Skip step 6 (detach the power switch on the motherboard connector) and focus on step 7 (connector to detach the LED on the motherboard). skip the remaining steps. Reinstall all parts except the LED Strip by reversing the above steps. That should do it.

• HP Pavilion 500 - 200 t: card memory HP Pavilion 500-200 t and upgrade information

  I'm about to take my 10 GB of RAM RAM 16 GB of RAM and 500-200 t has only two slots for memory card. When I replace (2 x 8 GB cards) I have two 5 GB cards flying over. I need to know the exact left specifications more cards? I want to put the card in my Dell XPS 8500 4slot who has already 2 x 4 GB cards in there. And the specifications on Dell cards are cards of DDR3 1600 MHz. Can someone tell me the specs on the HP 500-200 t maps?

  Please see the specifications of the product HP Pavilion 500-200 t and configurable Options page for the information you request. Based on the specifications, the factory in your computer memory should be 10 GB (1 x 2 GB, 1 x 8 GB) DDR3 PC3-12800. The speed is DDR3 - 1600 MHz. The size is a guess based on your statement "I'll have two 5 GB cards flying." Memory is available in sizes based on the binary progression... example... 1 GB, 2 GB, 4 GB, 8 GB, 16 GB, etc. There is no such thing as a 5-GB card.

  As to put in your Dell... it may or may not work depending on the latency and/or refresh, or if it is dual channel.

  If you have any other questions, feel free to ask.

• Satellite L300D - black screen but powers and FN light answer

  Hi, I have my friend L300D that is given to me to be fixed. I'm not a technician, but the kind of interested in the business of fixing :)

  Recently laptop screen just went black.

  Symptoms:
  -Laptop power on when you press the power button, but nothing coming screen.
  -Caps lock does not respond when you press him.
  -No hard drive light not flashing.
  -Power LED light and adapter lights up constantly.
  -Caps lock flashes once the first second
  -Laptop seems to continue to run with black screen but does restart or turn off.
  -Fan turns and no problem of heat.
  -Laptop can always power off when you you press power button for 5 seconds.
  -Is no beep or display any changes then from these modules removed from ram.

  He looks dead to me, but fortunately, it's not quite dead because the FN button seems blinking light under the F10 key. It is the only evidence that I have on this laptop telling me that it is not quite dead.

  I tried to put the latest bios file in a floppy 1.44 MB fat16 formatted in a usb floppy drive and the f key down before I plug in the charger, but still no change. I also tried B of WIN, the FN B, WIN ESC, the FN ESC.

  Please can someone give me some advice.

  Hello

  For me, it looks like serious hardware problem.
  What you can do is to test the device with an external monitor:
  Connect the external display and check if you see something like start screen for Toshiba, etc if you see something like that, then internal laptop screen is defective and must be replaced if not if nothing would seem-> the related problem of the motherboard.

• my iphone was droppped and custom lights, but you can which is a light on it as if it is in standby mode. is there any fixes for this.

  my iphone was droppped and custom lights, but you can which is a light on it as if it is in standby mode. is there any fixes for this.

  Try to do a reset. Hold home and buttons power together for 30 seconds or until you see the Apple logo.

  If that does nothing, there's a chance that the LCD connector has partially disconnected. Although it is most likely your LCD is damaged.

  Apple may offer a replacement of the screen. You must check in your country, how much they charge.

  Alternatively, you can look for a reputable independent repairer who can replace the screen for you. This means waive all the Apple warranty services. But it's a bit less expensive for a C. 5 If you go this route, choose a repairer who offers a guarantee of 6 to 12 months. And don't go with the cheapest.

• HP Pavilion g6-2231tx: capslock key flashing

  CapsLock key is continuously blinking but the pc works fine... Please help...

  Hi @vikalp007,

  A hard reset forces the system to erase and restore the software connections between the BIOS and hardware.

  When you perform a hard reset note remove all USB devices. Disconnect all non-essential devices.
  
  Please let me know how it goes.

• Satellite P10 PSP10E shutdown and the light stays on

  Hello

  I'm having some problems with my old man (2004) Satellite P10 PSP10E-0SCM7-FR

  One day he simply closed (as if power, no BSOD) and the power and the led for WIFI and the CD/DVD button remains lit.

  Most of the time I can't activate it under as the power button is still on. (Power button, WIFI, and CD/DVD are on).

  I tried to remove the battery and unplug the computer for at least 30mm
  I tried to press the Start button for a period of time (one minute) then disconnect everyting (battery and power cord) at least 30 minutes before to turn it back on
  I have reinitialzed the computer using history CD provided with the computer
  I removed the radiator cleaned as well as the fan and then replace a new thermal grease
  I changed the memory

  Yet I still have the same problem, for some reason, the computer simply shutdown and the light stays on. Occasionally, the power light start, and I am able to restart the computer. But I'm unable to understand what makes the computer is shut down, or when that happens, what makes the power light turns off and make it possible to start the computer again.

  No idea what's going on?
  The Start button / stop and led market would be an error message?
  If so, what that means?

  Any help is very appreciated. Thank you!

  Hello

  Usually, books closed due to the high temperature and in this case, the unit must be disassembled and cleaned professionally, but it seems that you already have what I read in your post above.

  Probably its a motherboard problem.
  The RAM modules appear to be checked and is not RAM issue.
  So problem mobo is possible
