My HP laptop is asking for Power On Password that I never setup.  How do I get around the password and how do I remove this setting so the problem does not recur?
My neighbor has asked me help with his laptop, an HP with lost power-on password. I tried inserting an Ubuntu cd to format the partition, but well... it doesn't even get there. Any ideas?
Is it possible now to use microtype with opentype fonts? How can I bring STAG back if I have 100% completion? There's a couple of the Saintsbook challenges that require you to have STAG forces available to kill.  After you complete the game, however, the STAG forces are nowhere to be found.  I believe that you can fight a few more STAG forces if you replay the final mission, but I think my save is glitched, so that's not an option.    Is there any way post-game completion to bring STAG back?  I miss their much nicer tanks and VTOLs for hijacking :( Ubuntu 14.04, Intel Chromebook, no sound How do I figure out what package something is in without resorting to Google? I often find myself wanting to install something, but I'm unsure of what package it's in. This is a very common occurrence for me:  $ make html sphinx-build -b djangohtml -d _build/doctrees   . _build/html make: sphinx-build: Command not found make: *** [html] Error 127  $ sudo apt-get install sphinx E: Unable to locate package sphinx  $ sudo apt-get install sphinx-build E: Unable to locate package sphinx-build   googles  $ sudo apt-get install python-sphinx   Is there a better way? Is this mold? Black? White? Guys I need to find out what this is- it's also on my wooden bed racks Limit of ${a_n}^{1/n}$ is equal to $\lim_{n\to\infty} a_{n+1}/a_n$ Today my lecturer put up on the board that:  If $\lim\limits_{n\to\infty}\frac{a_{n+1}}{a_n}$ exists and $a_n&gt;0$ then   $\displaystyle \limsup\limits_{n\to\infty}\left(a_n^{\frac{1}{n}}\right)=\lim_{n\to\infty}\frac{a_{n+1}}{a_n}$  however I am not sure why this is true, can somebody give me a hint or something as to how to go about proving this.  thanks for any help I found two things peculiar in the common style of macro definitions:   Ending lines in macro definitions with '%'; Not wrapping a macro name in braces.   Example:  \newcommand\examplemacro{%     \somecommand%     \othercommand% }   Being a software engineer first and a LaTeX user a distant second, I would expect:  \newcommand{\examplemacro}{     \somecommand{}     \othercommand{} }   Is there a reason for doing it the former way, or is it merely a matter of habit? Reserved words as names or identifiers Grepping logs for IP addresses To put it simple, there's a simple java swing app that consists of JFrame with some components in it. One of the components is a JPanel that is meant to be replaced by another JPanel on user action.  So, what's the correct way of doing such a thing? I've tried  panel = new CustomJPanelWithComponentsOnIt(); parentFrameJPanelBelongsTo.pack();   but this won't work. What would you suggest? I plugged in my external harddrive (which was formatted on my Mac into HFS+ journaled) to my Ubuntu desktop 9.04 64bit.  I am not able to get the drive to mount with write capability, how do I do that?  Right now all I'm getting is read access, I tried  sudo mount -t hfsplus /dev/sdf2 /media/"Portable HD"   but that still gave me only read access...  ideas?? Can I start and stop a tile floor job? I am tiling my bathroom floor and don't soon have a full day to dedicate to the job. Is it ok to lay down a few tiles each day and come back to the job when I have time? I would only lay mortar for the tiles I have time to lay each day.    My concern is that the mortar wouldn't properly "join" to the previously laid sections of tile and cause an inferior result, but I'm not really basing this concern on any facts. That is what I'm hoping to learn with this question. How do I know if food left at room temperature is still safe to eat? If I left food out of the refrigerator for some period of time, is it still safe? If I left it out too long, can I salvage it by cooking it more? The context is soccer (association football) and the sentence in question is:       The forward received the ball from the midfielder's pass.     I have already ask about this  and received alot of good answers, and I tried to leave it at that.  But then the World Cup 2014 is upon us, and I am starting to have doubts about this football usage of "from", to the point that I have semi-nightmares about it.  The use of "from" in the football example continues to bother me.  I seem to disagree (subconsciously) about how a ball (physical object) could be "from" a pass (action) unless that action creates that object.       Some people were hit by debris from the explosion.   The use of "from" in "debris from the explosion" makes excellent sense to me, because the explosion does create the debris.  But in soccer/football, the ball cannot possibly be "created" by a pass.    Is there any non-football usage of "from" similar to my football example sentence? Windows 7 SP1 Windows Update stuck checking for updates I installed Windows 7 fresh and installed SP1. Now, when I try to check manually for Windows Updates it just hangs on the Checking for updates screen.    I tried running the tools in , but this did not fix the issue either:  No matter what I do it just hangs on the "Checking for updates..." screen and goes no further. Where is the right place to register/enqueue scripts & styles I want to debug a router that is giving strange DHCP settings, but I don't know how to check it without having to make my system take all the configurations. Isn't there a utility that returns all DHCP settings (like NTP, WINS, DNS, IP, router) whenever a client connects?  Preferably that is platform independent, and that won't require changing the client's configuration to trigger the DHCP. Is the Ohm's law violated here? And also why is electricity generated at 11,000 V in India? Prove $\sqrt{2}$ is between $\dfrac{a}{b}$ and $\dfrac{a+2b}{a+b}$ Let $a$ and $b$ be positive integers. Show that $\sqrt{2}$ always lies between $\dfrac{a}{b}$ and $\dfrac{a+2b}{a+b}$.  Please give the easy solution as possible. Getting Session ID in Lightning
