How to fix dead pixels


Cheaper to throw away instead of trying to fix, if green is fading the rest will soon follow, I gather it must be near 4 or 5 years old as this seems to be the life span, sorry I have no solution as even dead pixel fixers will not restore lifeless colour, this is usually worn out caps and backlight.

Blotted screen in my hp laptop


1.Locate the problem pixel. Display a true black image on your HP's monitor. You can do this by playing a DVD on your HP laptop, and pausing it on the black screen just before the movie starts. Once you bring up a black image on screen, the stuck or dead pixel should be visible.
2.Try applying direct pressure to the problematic pixel. After you've located it, turn off your laptop. Place a soft cloth or rag over the pixel to avoid damaging your screen. A soft chamois works well. Using the tip of a pen, apply gentle pressure to the pixel. You don't need to press hard, as too much pressure can crack or scratch your screen. While applying pressure, boot up your laptop. This should force the pixel to begin working properly.
3.Tap the pixel. With your Toshiba booted up and an image on the screen, gently tap the pixel with the rounded end of a pen cap. Tap hard just hard enough to see a small white flash on the screen. Tap your HP's screen until the pixel begins working properly.
4.Download a stuck pixel program. Several programs, including JScreenFix, UDPix and Pixel Protector, are available for download and can help fix a malfunctioning pixel. These programs display rapidly changing colors and images on your screen. The flashing colors and images can force the pixel to begin functioning properly.
5.Contact HP. If none of the above methods work, your screen may have a pixel that is truly dead. If that's the case, the only option is to replace the display completely. Contact HP customer support at www.hp.com to find an authorized repair service near you.

Do you have advice in calculator choice between HP 12 c and the TI BA II Plus Professional Financial Calculator? Assuming that I get proficient with RPN (which I'm learning now); is one faster than the...


The 12C is more expensive and more powerful than the BAII+Pro. The HP is also programmable, which the TI isn't. Starting from scratch (assuming you've never used a calculator before---a somewhat unreasonable assumption) the TI might be easier to learn, at least initially. But after a certain point, the HP will leave the TI behind. The HP is faster and more capable.

There are at least three different versions of the 12C available. There's the original 12C, the 12C Platinum, and the current 12C. The only way to tell the difference between the two non-Platinums is to look at the battery compartment---the original uses three button cells while the newer uses two coin cells. The newer one is MUCH faster. The Platinum, however, can use RPN or algebraic.

Unless your choice is limited to the 12C or the BAII (by the requirement of an exam, perhaps), you might want to look at the HP 20B and the HP 30B. Programmability aside, they're even more powerful and easier to use and faster than the 12C, and the 30B is also programmable.

There are other considerations, of course. Factors such as the feel of the keyboard, the 12C's landscape orientation as opposed to the others' portrait orientation, etc, are all matters of personal preference.

Disclaimer: I own multiple HP and multiple TI calculators. I tend to use HP calculators for calculating, while I use TI calculators to answer questions here at FixYa.

I have death pixels.... can I do something with that?


Most digital camera's sensors have these so called 'dead pixels' or pixels that aren't functioning. It's normal for your camera to have dead pixels and you cannot do anything to repair it. But some cameras have a certain feature to resolve this issue, the process states that the user manually marks the area of the dead pixel and the camera will try to blend it so that it will appear to more natural. It works by blending the dead pixel to the nearest color of your image.

HOW DO I GET OFF RPN


The HP 12c is a purely RPN calculator; it does not have an algebraic mode.

To switch the HP 12c Platinum to algebraic, press f [ALG].

How can i tell the difference b/w hp12c and hp12p. i bought a hp12p from ebay(it's a stupid decision, I know!) and when i solving for IRR, i felt its running quite slow. I think the guy sold me the hp12P...


I couldn't find any reference to a HP calculator model 12p.
There is a HP 12c financial calculator and a 12c Platinum financial calculator.
Check both models (for images, specifications, functions, user guides, etc.) :
