For several days at a time, I get max speed from my TP-link wifi-N router. 50mbit down, as fast as my ISP gives me. Then after a few days, inexplicably the speed will drop by 30%, and cap out there. The whole time, my wifi adapter is still synced at 150mbit. When I change the wifi channel to...

When transferring medium files between 2 pc's on my network, I only get 140 KB/s. Both pc's have good-excellent signal. Where is the bottleneck? the router or the wifi chips in the pc's? I've never had a single wifi transfer touch even 1 MB/s Router is wrt54g and wireless cards are atheros...

Should a ups be discharged/charge cycled every now and then to keep the battery running longer? or do they die in <5 years no matter what?

My laptop has dual gpu- one crappy igp and one 6650m. When I run Chrome off the dgpu and try to play youtube 4k videos, it's choppy as fuck. gpu-z tells me that the gpu is not even being loaded at 45% the shitty amd quad core cpu is being hosed at 100% instead. How do I force gpu acceleration...

i wanna take one of these box fans and cut the noise with a voltage mod? It runs on 110v. If I buy a 220>110 step down converter (not transformer) and plug it into my 110v outlet, will that cut the voltage down to 55v to make it spin slower? And if that works, what about current? Do...

Acomdata external usb/esata hard drive suddenly stops being recognized by windows, front status light blinks red and blue, and there's a faint clicking noise. hdd inside is a WD Green 1TB. removed the hdd, hooked up to internal sata and power. Hdd runs fine, no clicking. I test the enclosure...

I've used linksys B/G and my isp's 2wire router B/G. My laptops all have atheros ar9285 wifi-n chips. No matter how close the pc's are, I can't get past 1 MB/s over wifi while transferring files between them. Both netbios and ftp max out at 1MB/s. But downloading directly from the internet...

seagate 500gb 2.5" hdd. Ran seatools multiple times, but there are 1-2 stubborn bad sectors which it won't reallocate. Same sector repeatedly fails even after I tell seatools to fix it. tried linux live cd hdparm to manually force sector reallocation, but it still won't trigger the drive to...

All the tegra 4 partners seem like low volume sellers. MS surface, toshiba, hp slate. nvda isn't going to sell shit like this.

Big ugly cubes on your wrist. Since when was that stylish? I bet smart watches will flop

My klipsch 4.1 speaker volume knob can't be remedied anymore. Several years ago, some wd-40 cured the scratchy noise. Now it can't be cured, even with contact cleaner sprayed inside the potentiometer. it's back with a vengeance. Speakers still work, but the scratch is annoying. This is a quad...

I just got a new WD laptop hdd. I used WD's lifeguard diag tools to do an "extended test" on the empty hdd, but I'm wondering if there's any point, i.e if there's no data on it, how does the tool know whether the sectors are readable or not? It's just reading 00's and thinking it's ok? This is...

You see those $8 usb3 2.5" enclosures on ebay. Do they work well? I'm not looking for the fastest speed, but I need something that won't break.

^ I have one of these bricks. it's rated for 20 watts, and outputs 30vdc and 500mA. Is it possible to hook up 80mm case fans directly to the power brick by splicing? I will probably hook up 2 fans. I want to make a cooling mod for my laptop.

Note: I am not asking how to apply grease. Here's the grease you typically see on laptops straight from the factory. They use the large pea method, then clamp the heatsink down. grease oozes out the sides, and surrounds the die completely. Many people have parroted that this 'insulates' the...

I noticed how all the office/electronics big box stores are still selling sandy bridge i3's. There must be a shitload of inventory left. Last week, Intel said their sales would drop for the remainder of the year. but SB i3 laptops are still priced at $400+. Pretty dumb they're not dropping...

Fark that ! currently, Dell biz has some touchscreen options for their laptops. a 1366x touchscreen costs $175 more than a nontouch 1366x. I wonder what kind of price premium these upcoming touchscreen win8 ultrabooks will have over nontouch. Dell ceo already said touchscreen...

those newer laptops with 2 dimm slots and 4 + 2gb = 6gb ram... does that run in dual channel mode ?

my laptop has these silver kinds of caps. are these more heat durable ? I'm thinking about doing some cooling case mods to my laptop, however it will result in increased heat in area 1 under the trackpad. I'm worried about busting a cap when it gets too hot inside the case. Right now...

Trinity has faster integer units. but which apps take advantage of them ?

Everyone and their moms want apple? It costs 2x monthly salary in china to afford one apple goody. If those guys want an ipad or iphone to go with, it will be 4x, and a malnourishing purely rice diet for the next 8 months. Those crazy chinese people. You think they're crazy?

A stupid limitation of the mobile llano with dual switchable graphics is that opengl is always rendered on the weak igp. I am wondering if this is also the case for the desktop llano. Does anyone here have a desktop llano with an AMD pci gfx card, and when you play opengl games or use opengl...

almost every laptop has this atheros chip. yet it runs like shit. I have tried 2 different routers, updated to latest drivers. I even checked driver settings to make sure it WASN'T locked in wifi B mode or something. Doesn't matter if the router is 5 ft away or 30 ft away. I tried the WRT54g...

I see all these new hybrid combinations in the Llano series. i also see that amd hybrid graphics has been around for several years. But it's basically broken in the Llano. AMD hybrid gfx is DOA. I have a radeon hybrid crossfire setup in my llano laptop, and the hybrid graphics is almost...

edit- when I use dvi output to lcd monitor, no banding. when i use hdmi output from laptop, i get banding. color is set at highest 32bit. decreasing contrast doesnt eliminate bands. i thought hdmi and dvi output was supposed to be identical. in this case, they are not. hdmi looks shittier...

I still have not seen any llano laptops, particularly the A6 and A4, demoed in big box stores. You think intel is paying stores not to put out llanos?

on my old a8n-sli board, the keyboard ps/2 port stopped working. the mouse ps/2 next to it still works. when i plug in my keyboard, the numlock and other lights light up for a split second, so there's definitely power. how do i fix this... ? ( I already have a usb keyboard, but i want to...

anyone notice how llano's Passmark scores are higher than most sandy bridge cpu's, even though SB wipes the floor with llano on every single computing job ? that's pretty misleading. no way a llano A4 beats a phenom x2 555

I think I have one of the last laptops in existence that opens 180 degrees. all laptops I've seen recently only open about 120*. WTF is up with this trend. Are the current hinges supposed to be superior to the old ones? it's not hard to make a hinge that opens 180* but the current stupid...

I would like to know which mfgr sourced this panel. http://i53.tinypic.com/2jdki2b.jpg

Is there a perfect matte screen? i think the antiglare coating on my led-lcd monitor is causing blotchiness on a purely black screen. it's not a cloudy effect. it looks like vertical bands of a darker shade. One is noticeable slightly right of center, if you see the pic below. my glossy...

I got a new asus TN led lcd monitor recently, and it has a feature that lets you have a better viewing angle, e.g. when you're lying on the floor, or viewing from the side, etc. i pushed the button, and all it did was jack up the brightness, washing out the colors. Then I recalled that Samsung...

anyone have a slick method to get the RGB colors as accurate as possible? I bought a cheap new asus led backlit TN panel, and the colors are too vibrant. almost neon. I was thinking of going to the local drug store and developing solid 4x6 sheets of red blue and green, and then holding them...

Has anyone here drained their battery on a daily basis? how many years has the battery lasted?

I have an old Dell 1907fp with a samsung TN panel. It's a matte screen, and viewing angle is actually quite good at 170* above the monitor. A picture pretty much maintains most of its color. I have a laptop with a glossy widescreen TN samsung panel, and viewing angles are absolute shit...
