    Woe unto HP and their terrible post-sales support!
  2. HP is a shares holders company. theres no such thing as quality anymore. they will cut corners put cheap parts in computers,your tech support goes to india to someone reading a script off a screen. i feel bad for anyone buying HP product, the company made its $ now it dosnt care. i bought a HP laptop it burnt out in 3 months they did nothing for me. quality is non-exsistant

    boycott HP and never buy their products again
  3. DON"T BUY HP!!!! have brand new! desktop pavillion and had nothing but trouble with since,now is just 2 months old and has hard disk failure imminent and unusable, still waiting for tech to replace hard drive, i figured being so new i may get replacement, hp have done nothing to help so i wait here still for repair.

    signed ****** off beyond belief!!!!

  4. I have an hp laptop with the corei7 that was garbage out of the box and I sent it in for repair and it came back worse than before I sent it in so I requested a refund and now hp will not return calls. Has been escalated 3 times with the promise of a callback in 24-48 hours but its been a month...still no calls from HP. I will be writing a letter to HP, better business bureau(I know, futile) my states attorney generals office and anyone else I can think of. I just want a machine that will work better than my old toshiba celeronM 1.47 ghz! Its a shame I have to keep using that old $300 laptop when I paid over $1000 for the new HP!!!

    I've been dealing with a bad HP Pavilion e9180t since fall of 2009. Right out of the box it crashed with a BSOD part way through the first boot into Windows Vista. It then continued to blue screen every half hour or so until I shut down all power management that I could in Vista. That reduced the blue screens to one every couple of hours or so. The Bios is useless and has no power management ACPI options at all. I tried sending it to HP for service. HP's repair amounted to only formating the drive to the original image and returning it with the same problems, so I decided to explore fixing it myself by going to Windows 7 in case it was a Vista issue. I upgraded it to Windows 7. This helped a little and the BSOD frequency reduced to once a day, unless my wife goes on Facebook in which case it crashes every half hour again. With this said...I've noticed that frequent variation in processor load from idle to moderate (as happens with Facebook) makes things worse.
    The most common Blue-screen error is "A clock interupt was not received on a secondary processor within allocated time interval". Windows just memory dumps to protect itself. I suspect that maybe the Motherboard has trouble with power regulation during high speed load rep-rates or trouble speedsteping the cores on and off due to load variation. I'v invested hundreds of hours troubleshooting... everything points to the MB. After removing most of the HP fluff software things did improve a bit, but I still get a BSOD every few hours of use.
    HP tech support never acknowledges the possibility of a hardware issue since the machine passes all of their hardware diagnostics. They've asked me to return the machine again in order to re-format it back to Vista. It's still under warranty, but I hesitate returning it again to just repeat the same path and have to spend more time getting the software back to how I had it. Even if HP does replace the MB, I'm worried that they'll just replace it with a refurbished "Truckee 1.04" that has the same problem or worse.
    Another box arrived today from HP to return this nightmare back for service, but I've lost all trust in them. Maybe I should just replace the MB myself with a good hobbyist brand and forget HP. After this experience HP just leaves a bad taste in my mouth.

    I have some good news for any folks still struggling with Blue Sceen crashes with their HP I7 machines that us the Pegatron IPMTB-TK (alias Truckee-UL8E 1.04) motherboards. I've live with these constant crashes since day one as stated in my previous post. HP refuses to change the motherboard, stating that the machine passes their diagnostics. All I can say is that their diagnostics are poor and don't do CPU load testing. I believe that the problem is due to a poor motherboard power management design and/or motherboard PC layout. The motherboard can't handle any CPU load variation that forces core parking. I was able to prove this by turning off core parking. It eliminated all crashes and finally make the machine stable. All that I had to do was make a simple registry edit that prevents core parking.
    With 100% core parking allowed (the Windows 7 default) my HP Pavilion Elite e9180t machine crashed ( with BSOD) whenever anything caused any significant CPU load variation (also know as high rep. rate). Something as simple as going on Facebook with IE and playing one of their mindless games would cause a certain crash within a half-hour or so. Turning core parking to 0% in the registry eliminated all crashes. My machine has been crash free since I made the registry edit. Many BIOS's settings allow turning off Speedstep and Turbo which should have the same effect, but the Truckee-UL8E has no power management settings at all. Fortunately, a Win 7 regestry Key edit does the same thing.
    Check out the following link: http://forum.cakewalk.com/tm.aspx?m=1861804
    ---------------------------------------------------------------
    Above link provides the following simple instructions on turning-off Win 7 Core Parking:
    "In short, here is the better method from sky60234:-

    - Go to Regedit

    - Find this key:- " 0cc5b647-c1df-4637-891a-dec35c318583 "

    - Within this key, there is a value called: " ValueMax "

    - This value represents the % number of cores the system will park - the default 100% ie: all Cores are potentially park-able

    - Change the value from 64 to 0 so the " ValueMin " and " ValueMax " are both zero

    - You will have to find the key a few times and repeat the process for each time it is found - the number of instances will depend on the number of power profiles in your system [ in my DAW it was only found twice ]

    - Do a full shutdown and power-off and cold-re-start
    ------------------------------------------------------------------------
    Now my machine is stable... no thanks to HP. The extra heating from turning-off the core parking is insigificant. The core temperatures stay around 40C. It just sucks up a little more power...not green as HP advertizes. I hope this works for others and proves to HP that it is a motherboard issue...
