If your laptop wakes from standby inside your bag or backpack, it will likely overheat and possibly self destruct. Even if it survives, this takes life away from your hard drive and motherboard by getting so hot!
It cannot ventilate when running inside a laptop carrying case.
Laptop overheating causes:
Cause 1: USB mouse with nano receiver plugged in, when you get anywhere near the laptop, like putting it in your pack and lifting it from your desk to go out, it already is coming out of standby if your mouse isn’t completely disabled.
There’s a bug in windows settings that still allows the mouse to wake up the computer out of standby even if you have it set to not allow the device to wake up the computer.
Cause 2: Plugged intake vent on the bottom, if you lay your laptop on a blanket or on your lap, make sure you know where your intake vent is and be mindful to keep it open to breathe air. Usually the exhaust is on the side or the back and is harder to block, plus you’ll feel a hot spot if you do plug it.
The clue: Dos prompt -> powercfg lastwake
Even though I had my nice new Logitech M325 mouse set to not “Allow this device to wake the computer” (unchecked), it still would wake up my laptop. This is dangerous!
The range on these mice are incredible and if you put your laptop into standby in a bag with the micro USB receiver always plugged in, as I do, you can accidentally bring your laptop to life. Possibly not for long with the heat factor of running inside a backpack…
Device Manager->Mice and other pointing devices->HID-compliant mouse->Power Management (tab) uncheck “Allow this device to wake the computer”.
Also the keyboard HID device must be disabled from the wake up call! (not your keyboard, that still wakes up my computer, as it should be)
Device Manager->Keyboards->HID-Keyboard Device->Power Management (tab) uncheck “Allow this device to wake the computer”.
Hard faults per second is just not having the info you need cached in RAM.
Don’t worry, Hard faults per second on Windows are not hard drive errors like you may think. They are simple pagefile accesses instead of RAM access.
You may see from 0 to more than 100 and it’s actually ok…well if you’re getting more than 50 or so, you’re system is running much slower than it can and most likely rattling the heck out of your hard drive.

This problem can be caused by overclocking, overheating, a hardware problem, or a BIOS or firmware bug or configuration issue.
To determine if the mainboard, memory, or CPU is at fault:
If the memory diagnostic does not report any errors, check the following:
Start a Command Prompt and then run chkdsk x: /f where x: is the drive to check.
For example: chkdsk c: /f
Note: If running Windows Vista or Windows 7, you must run chkdsk from an Administrator Command Prompt.
If none of the above helps, the problem may be due to weak sectors on the drive surface. If the issue you are having involves a hard drive, download and run the hard drive manufacturer’s diagnostic utility or a third-party utility designed to scan and repair hard disk surfaces. Below are links to some major hard drive manufacturer’s home pages:
If you still have not narrowed down the problem, try adjusting the system BIOS parameters below, for the drive(s) with which you are experiencing the problem. These settings, if available, are typically found under “Integrated Peripherals” or in the “Drive Configuration” section.
The winsxs folder bloats as you uninstall apps! This is counter-intuitive to gaining hard drive space huh? Within a week of running Windows 7 many people report a windows/winsxs folder to be 5 Gigs and as much as 10 to 12 Gigs.
What is the winsxs folder? A complicated mess that microsoft made, like the registry but even more of a black box space hog.
It contains manifests, dll backups, service pack backups, libraries for executables and other serious sounding junk. So many MS guys advise not to touch it that even I…windows modder and tinkerer from the win3.1 days have not dared delete any of the jillion little folders which turns out to the the bulk of my 5.5 Gigs of use.
My advice is to image your hard drive fairly often and when you want to uninstall stuff, go back to your image instead, of course after you’ve made sure you’ve copied your docs and bookmarks etc.
My Favorite Hotkeys for Windows 7:
Windows Explorer (file manager): Alt+Up: Goes up a folder level in Windows Explorer.
Backspace: is like back button (may be forward, may be back)
Alt-Right:is like back button (may be forward, may be back)
Win+Space: All windows become transparent so you can see through to the desktop.
Shift+Win+Up arrow: Maximize the active window vertically.
Shift+Win+Left/Right arrows: Move the window to the monitor on the left or right.
Double-Click Top Window Border (edge): Maximize window vertically.
If you have the error on a linux system: “error splicing file permission denied” while trying to move, copy or delete a file, most likely you are trying to copy a windows encrypted file. It will not show as encrypted in linux and the permissions will look exactly as your others that do copy properly.
The best way to take care of this is to boot into windows that encrypted the file in the first place, and right click “properties”, then uncheck “encrypted”. The files will decrypt if you logged in the windows that originally encrypted it.
I had accidentally done this and the only way I noticed was the file copy error in Ubuntu, then when booting to windows, the particular folder full of files were all in green text instead of black. If they were in blue, that would mean that they are compressed.
You can start System Restore from a command prompt window if you can’t start your computer in any mode other than safe mode with command prompt.
Start your computer in safe mode with command prompt. For more information, see Start your computer in safe mode.
At the command prompt, type rstrui.exe, and then press ENTER. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Windows 7 fixmbr:
This is a Malaysian computer blog which I find interesting, visit it if you like the tutorial below!
The following tutorial will teach you “How to fixmbr using Windows Vista bootable disk“.
To fix grub after installing windows destroyed your boot sector:
…any time you install a copy of windows it will erase grub
its a simple fix..
1. boot live cd
2. open terminal
3. sudo grub
4.from grub prompt do this
it will give you something like this (hd0,0)
5.use the disk that you found with the command above for this next command
(remember to change the numbers to correspond to whatever you got in the previous step)
6.setup (hd0) (notice how i left out the ,0) thats not a typo!
it should give you some type of confirmation that it worked
then you can just quit grub
then exit the terminal
(you will need to add windows to your /boot/grub/menu.lst)
