Its a HP laptop charger, which had the infamous shortcircuiting issue which was fixed using the instructions here. Now the other end of the adapter, the DC input jack which goes inside the laptop gets very hot. I can touch it easily when I am holding the plastic cover, but removing it and...

My HP 2180 printer buttons panel freezes. Trying to press buttons won't help, sometimes when I try turning on the printer just a single ink catridge light will light up and won't do anything else. Sometimes it starts normally but when I try pressing one of the buttons it does nothing. I even...

Hey I am trying to learn about internet security as much as possible. If someone over here is familiar with management information systems then that'll be great. I am academically qualified for relevant fields but I wish to get the latest happenings around and I am not a big fan of academics...

I just noticed something very strange in IE9 browser history and wondering how can that be happening. In the history tab of view by order visited today, I am seeing some .ini and .txt files that I have on desktop and IE9 is taking them as IE shortcuts. Even thou, they were not downloaded or...

Fixed .. I removed the battery, uninstalled it, placed it again, let it reinstall by itself and now its working fine. Souds like a problem with OS drivers or it can be hardware because I was charging it before on a UPS ( uninterrupted power supply )?

Battery appears to be fully charged when connected to AC supply but as soon as the AC supply is removed it suddenly drops down to 90% and from there everything is normal. I've seen stuff similar to that, but this one doesnt seems to be very normal.

My laptop just came back after servicing and the only vent which throws air out of the laptop is cleaned properly and thermal paste applied. Temperatures have improved and I would love them to stick that way. Now I don't want the debris to build up again so I am using a hair dryer which throw...

My Compaq Presario CQ40 is hitting 78C with some load, around 50-60C when idle and 92C while doing some light multiplayer gaming ( HALO:Custom Edition ). Atmospheric temperature is 86C where the laptop is located and the laptop doesn't have an in-take vent. Just one vent and it blows the hot air...

Its my personal laptop and I have an internet connection where my network administrator has a broadband connection which is shared amongst its users.

I am trying to check if certain ports are open using PFPortChecker and few online port check tools and even basic ports like 80, 8080 and 24 appear to be blocked and yet I am able to browse web sites etc which are obviously using those ports. Have my network administrator made such a setup, how...

I was just wondering if viruses which can permanentely be placed on your computer still work? I've heard about how computer BIOS are far more secured and its not possible to get viruses executed from ROM but is it true?

I am a little confused, since I enabled automatic updates in my previous windows, it slowed it down. Now I have a fresh install and I am wondering should I enable them or not, either get the speed at the cost of lowering windows quality or are they really important for my hardware.

So I had two windows 7 installed on my PC ( don't ask why :D ) one in C:\ and one i D:\ I went inside the system recovery procedure of my D:\ windows 7 and formatted my C:\ drive, now when I restarted I started getting this error BOOTMGR is missing hit ctrl+alt+del to restart.. Now, I...

Still looking for a confirmation :)

Sounds similar but possibly something else because I have seen laptops with diagonal lines all over the screen Is itexactly what is happening with me? Animated diagonal lines only at the bottom half of the gradient image? Thats not an issue, its possible just the discoloration when you were...

And thats only for gradient backgrounds? Unfortunately for me its just 65hz option so I can't check if they disappear at higher refresh rates.

I see but just to be sure, If you try seeing the gradient image I posted, you should be seeing "diagonal" lines moving from right to left or otherwise at the bottom of the gradient image. If the lines you are talking about are horizontal, then that is another issue which will go off if you...

Anything which is resource intensive will eat up your battery as well. If your only concern is the laptop's battery power than look for laptops with 12-cell batteries.

Great, so I didnt mess up my laptop after all :) I have a refresh rate of 65hz ( maximum ) with a color depth of 32-bit, so yes the refresh rate isnt that high that may be causing this. By the way which LCD do you own?

No actually, I meant when I am viewing my laptop LCD from an angle where the image looks dimmer than when viewed from front. I notice "animated" diagonal lines over gradient background. I was wondering if thats normal.
