Older, hotter ran laptops breaking tabs related? (XPS 15 P31F)

o, customer gave me this, keyboard had issues with keys and cleaning them did not seem to fix them, so replaced keyboard

On reassembly, MHF4 connectors on wifi antenna were warped, bent up wifi card connectors (didn't see until did a high magnification on them)

Ordered new a antenna, wifi card. Went to replace it and all the tabs where the screen cable/antenna holder broke when I was trying ti take it apart (non marring pry tool)

I noticed the keyboard had a copper sheet. Further looking into this, it's because how hot this thing ran (nvidia gpu and...

Picking one that is a good amount above requirement voltage (say 25v for 12v instead of 16v) increases life too, but there is more information involved to really determine if this works, and it's not just voltage, probably ripple too, but I'm not sure about uF

Voip options for new setup

So, I have an auto shop company that is paying $250/mo for a old analog telephony pbx connected with a spectrum voip phone system and 5 phones, that are from 2015, and two have died thus far

In 2010 I ran trixbox at a (very small) pc repair company I worked for and it's not updated anymore. I so I have...a little exp with asterisk based voip

Should I mess with asterisk on linux, or get a hosted voip like 3CX?

They don't do much advanced stuff, but even with hosted 3CX it can run ~300/yr, which is significant savings and I don't have to be the support person...

Re: DIY PCIe x1 video card...

That is what I thought. Come to think about it, since it was a server, that slot was likely supposed to be a raid card. Dell might have made the PCI-E bus not to support the full 75w...

Re: DIY PCIe x1 video card...

I cut off a x16 8400gs to x8 with a dremel it did work, but when I tried to load drivers it froze. I think it was a power thing. Should have tried it on a card with a separate power connector

SMD coil whine "chirps"

Does anyone have high frequency sensitivity hearing and a motherboards have tons of sounds coming from it? Is this just coil whine en masse? When data to the SSD has high I/O I can hear the clicks and chirps. Same with when the graphics drive inits. Network adapters, chirping after I connect the cable

I can hear everything. Every time I put my ear to let's say an open Shuttle XH series pc (currently working on) in the next room it sounds like I'm in the middle of a the fucking public bird aviary

Of course this isn't just the shuttle, though I think the small case...

I just put 64-bit on and it says all 4GB. Not sure how much of it is actually video shared

found out it's 16M GPU shared. Thank god. I've seen 128M+ from 4GB of ram...

Ugh in 32-it (current OS) after upgrading the ram it lowered the available ram to 2.9GB

Which is better? 32-bit or 64-bit on the edge of max 32-bit memory (Win7)

So I have a customer who I upgraded his compaq CQ50 (which other than the screen looks like it could survive a two story drop-with an sSD anyways)

I've dealt with this model years ago before but with just virus removal

I've been doing a full upgrade, including a celeron to C2D 6670 (updated bios ahead of time and this works great, also a good ebay deal for $14)

i'm soon going to be doing a fresh install, and I'm curious, I've done 32-bit installs with low memory that get better performance due to the lack of WOW

Now that I'm going over...
