Started as a hobby now it's a passion. Tearing down and up electronics just makes me forget about everything and I love technology and electronics.
Antwort auf „How much is the battery life reduced by increasing RAM?”True, but different components drain different amounts of power from the battery. Memory is a negligible factor, because it uses very little power (we're talking less than 3 watts per stick in a laptop). And in fact, if you have a HDD, more memory usage would theoretically increase battery performance, because there is less HDD activity when memory is used as cache, instead. The most power hungry components are ones that generate heat (CPU and GPU as they process information) and those that generate physical motion (the fans and any hard drives). Memory tends to generate relatively little heat (and obviously no physical motion). The first steps I would take in increasing battery consumption would be to replace the HDD with an SSD, get a new battery and maybe replace the fans with those of better quality (harder to do on a laptop). Also abstain from any GPU or CPU intensive tasks. Any efforts beyond that are adding immeasurably small amounts of battery life.
Antwort auf „Why is my laptop saying BOOTMGR”Hi there, Turning on your PC, only to be greeted with the words BOOTMGR is missing, is a panic-inducing experience. The BOOTMGR is a program that runs when you start your PC, and loads your operating system from the hard drive. When it is missing, Windows is unable to boot. Even advanced users have many questions when this error turns up. Is my computer dying? Is my hard drive failing? Is my data safe? There are a number of reasons this error could occur — everything from a loose hard drive cable, to a bad OS upgrade, or even the occasional fluke. It can be caused by many things, make sure you have no CDs or DVDS, USB drives or any external storage drives plugged in. your computer may be trying to boot from one of them. Try changing the boot order locate in the BIOS, if you have Windows 7 installed on it insert a Windows 7 DVD, boot it click install and after setting the Date/Time, Keyboard layout, etc. Click on theRepair your computer button located in bottom left of the screen and then choose Startup Repair...
