First I'll address the HP Pavilion DV6000: Started out with just a grainy, wavy line display. At first I was able to add an external monitor & the screen on the external was perfect. Correct me if I'm wrong but I take it that the problem is the screen on the HP since the graphic's on the HP would also control how the external monitor would look. Then, I could not even get the external monitor to turn on [no signal!] After hours of taking it apart, checking all the connections, I've come to the conclusion that the battery which is no good & a power supply that has been the really only true source of power for about 8 months is starting to go bad. Below is the steps I took in order.
1: Notebook Screen wavy/grainy but external display worked fine.
2: Took the notebook apart, changed the heatsink fan [which was going bad], checked connections & put it back together.
3: After a few times of turning the notebook on, then the external monitor would not show up: "No Signal" flashing on the external screen & notebook stay's in "Power Saving" Mode.
4: Decided to look at the battery as the problem. Charged all night & only had 9% charge the next morning with PSU still plugged in.
5: Since the notebook stay's in "Power Saving" Mode, I am assuming that the problem is the notebook is not getting enough power to run the nvidia graphic's correctly. [that's the other problem, the nvidia chipset]
So as far as the Pavilion, I guess it need's a new battery & probably a new PSU.
Next we come to the Toshiba Satellite A135-S2276 notebook. This was one of those $30 "Cracked Screen" specials I purchased on ebay. Now this one is really strange. Please note that I am aware that there have been mainboard issue's with the Satillite A135-xxxxx models but read on because I've never heard of what is going on.
1: I had it in the house & tried to get it to work but could not get the external display to work. I left it in the garage.
2: The "Gateway" PSU that came with it went bad. After about 6 months, I went into the garage, [cold outside] & it powered up. First I thought, the battery must be good so I'll mess with it. I mean come on, 6 months left in the garage through the winter so it must have a good battery!!!
3: I attached one of my LCD monitor's to it as the external monitor, [Note: With the original hard drive in it, I couldn't get the external to work so I put in a new hard drive.] Since I have the original restore disc with OS & drivers/apps I am good to go.
4: The first time I turned it on [still in the cold garage], I got a "Enter Password" so I stopped & figured that I'll have to go into the BIOS to see if it's password protected & clear it if I have to, but do remember that "1234" was the password.
5: I decided to bring it into the house & "No Display's" when I turned it on. I do believe that I had it apart & checked all the connections but now I'm wondering if there is a issue with the board it's self. Like I mentioned earlier, the A135's do have mainboard issues.
6: With the new hard drive installed, I can turn it on & first I get the bootup screen on the external monitor that show's the "Press F2 to enter setup" & the "Press F12 to enter boot menu". That's as far as I can get.
With all that I've noted, does anyone have any idea's? If you do, please list either the HP Pavilion or the Toshiba Satellite
One thing about the Toshiba Satellite A135-xxxx. What I need to add is that the processor heatsink fan does spin when powered up as it should. Also the hard drive is running/spinning, so there is power going to these two. Like I said earlier, it will work if it's been left out in the garage. Here in Michigan, it does get cold & I did look at the notes I kept, the battery has held a charge for almost a year. So the original seller was honest when he said the battery was at 90-95% new.
I'm hoping I can get a Tom's Hardware member to answer my questions about both the HP & Toshiba. Thanks again, Dan
