Your system may be in CRT mode for a external display; press the "Fn" key and the "CRT/LCD" hotkey to change the monitor mode. Furthermore, your battery could have died while your laptop was in a suspended state; removing the battery and unplugging the laptop for the power supply for 30 seconds should reset the power management system.

On booting up my Inspiron mini 1012 netbook it keeps displaying 'the user profile service failed the logon' and 'user profile cannot be loaded'


Try logging in on the admin acct then delete and recreate the profile. If it doesn't work you can try switching off the comp then continously press F8 while turning on the comp and choose safe mode, then do a system restore.

When you are in "comp"


The "Deg" indicates degrees are the unit used for trigonometric calculations. You can use [MODE] [5] to switch to radians or [MODE] [6] for grade. [MODE] [4] switches back to degrees. This is independent of "Comp" mode.

Samsung hdtv to compaq pc


There should be a setting within the comp. Is it connected to the comp monitor and the tv? Perhaps from the comp to the tv with the monitor from the comp as well? Well if so, you may need a certain setting within the comp. Check under (on xp) display properties, and then under the settings tab. Please rate!

PROBLEM W/ CASIO fx-260 SOLAR


Sorry, but I think you misunderstood what the manual says. See the not on the screen capture.
True the sentence is not very clear, but what it means is the following:
All modes (except COMP) will have an indicator (with the appropriate labeling) displayed. When in COMP mode the COMP indicator is not displayed.

The truth of the matter is that computation- wise you have two MODES only : the general COMPutational mode and the Standard Deviation (SD Statistics) MODE. These two are incompatible because the key layout is different.

But to compute trig functions
  1. calculator must not be in SD mode, hence it is in COMP mode
  2. An angle unit must be shown on display.
Read the screen capture about the MODES of this calculators. DEG,RAD, and GRAD remind the user that the angle units in trigonometric function calculations and coordinate conversions are in degrees, radians or grads. They have nothing to do with the other calculations you are doing.

You can only remove DEG by changing the angle unit to RADians or GRADs. In so doing, the new unit indicator (RAD, GRAD) will be displayed instead. There is no point worrying about the angle unit indicator unless you are performing coordinate conversions or calculating trigonometric functions or the inverse trigonometric functions.

MODE 9 cancels the FIX display format: decimal are displayed with a fixed number of decimal places (set by the user). After this key sequence the decimal display format reverts to NORM(al).

Compaq presario evo 1015v


sounds like a bad screen this might be able to be remedied by hooking the laptop straight to a computer monitor threw the ports provided in the back
also you could have bumped something loose inside like a video card if any cards or memmory comes loose this will give you black screen of death the laptop will have to opened and cards pressed down gently
theres the solution of your power supply on the laptop went out and you need a replacement
if power supply went out it doesnt hurt your comp it just makes it hard to run

Comp will not turn on also see lightning bolt display


Hi All,


This happens because of static energy storing in the motherboard components.

We can try power drain to resolve this issue.


Try doing power drain by taking out the battery & keep holding down the power button for complete one minute to drain out the power from the computer components. Restart the computer after putting the battery in.
Try restarting the computer only with the AC power, without the battery & vice-versa.

That should resolve the issue, if the issue persists, then you have to contact service center.


Hope that information helped you!!
