Regardless of the potential for permanent damage, what hardware changes can I make to a Dell Inspiron 7559 laptop?

I saw added carbonite pads to save space between the vent and the fan, cut out holes and replace the 1920 LCD monitor with a 4k touchscreen. Are there "extreme" changes I can make or replacement parts to replace OEM laptop parts? Is it even possible to solder on a new processor?

Hardware design: FAB icon with several different actions

Current situation: Under the FAB button, we have several different actions –

  1. Modify the element
  2. add a comment

Problem: The "+" FAB icon seems incoherent, incomprehensible, users get confused because they do not expect to edit an item, under the "add" button.

Question: Need ideas, how we could change the FAB icon so that it is understandable. We use hardware icons: https://material.io/tools/icons/
As for the users themselves, do you see a more appropriate icon for this scenario? All answers will be appreciated!

pci dss – Is the end-of-life hardware PCI DSS 3.2 compliant when it is still supported by a third party, not the current provider?

I've been working for an ASV PCI for five years. This is not consistent – you can not make sure that you are fixed for security vulnerabilities if there are no security patches to apply.

However, your PCI ASV can, at their own discretion, choose not to let you down for that. I have seen clients in situations where the software change would cost many millions of dollars or that there is literally no other option. To solve this problem, they usually apply secondary security controls to mitigate the risks, for example by isolating a Windows application in a well configured Citrix XenApp instance on a Terminal Services server, with an AV installed (and up-to-date!) And an operating system. lock in place. Or, for a Web application, install a WAF and create custom WAF rules to prevent exploitation of known vulnerabilities (for example, XSS) as they occur. In any case, this involves a thorough evaluation of the safety of the product EoL & # 39; d to determine its level of safety and its risks. In most cases, this also involves providing your ASV with a long-term plan to replace or abandon the EoL & # 39; d product.

Your ASV should absolutely mark non-compliant components of your network or system as non-compliant, but they can also mark it as an exception (with justification) and give you an overall assessment success.

wi-fi hardware disabled in Ubuntu 18.04 how to fix this problem?

I'm using a 4755 acer laptop with kernel proc i3 2310m. he can not activate the wi-fi. under Windows OS, acer laptops usually use the fn + f3 keys to turn on the wi-fi, but that does not work. How to install the driver correctly and how to activate it?

hardware – Example of complex Fourier series

The complex exponential Fourier series of a signal over an interval 0 t To is (a) Determine the numerical value of To (b) What is the mean value of x (t) over the interval (0, to)? (c) Determine the amplitude of the third harmonic component. (d) Determine the phase of the third harmonic component. (e) Write an expression for the third harmonic term of the Fourier series in terms of cosine.
Anyone can solve it?

Hardware vulnerabilities of the external hard drive

You have an external hard drive that has been left in a public place. The data is encrypted.

  1. What are the hardware or software vulnerabilities that can be used to get the encryption password when decrypting it?
  2. Is it possible to know if the software or hardware of the hard disk has been modified with these vulnerabilities and if its use is safe?

Hardware damage – The lens does not lock on the Nikon D7000

A strap is broken on my bag. My Nikon D7000 had a heavy 70-200 2.8 attached. When I took it out, the lens was detached from the body and did not twist to lock itself. I tried the other goal that I had with the same result. I tried the lens on my other body, and that was fine. Can this body be repaired?

Hardware – High Performance Heat Sinks for LGA 3647 Narrow

I plan to buy an aluminum heat sink: https://store.supermicro.com/1u-passive-cpu-cooler-x11-snk-p0067ps.html

Versus of a radiator with a copper base / fins and a steam chamber: https://www.dynatron.co/product-page/b4a

Does any one have any experiences with "amateur" heatsinks for LGA 3647? Will a good thermal paste, such as the Arctic MX-4, combined with sophisticated heat sinks such as steam chambers and copper, make a big difference?

hardware – Diagnosis of the SMC problem on a damaged liquid A1932

Unfortunately, I spilled coffee on a Macbook Air A1932.

The problems I am currently experiencing are:

  • the laptop will not run on battery, only if AC power is connected
  • I experience the behavior (somewhat common) when the fan is still running at maximum speed and the processor is still throttled, probably because of a malfunction of some temperature sensors
  • Apple PPT006 ​​Diagnostic Reports (Battery Requires Service) and PFM006 (SMC Problem)

Before bringing the device to the Apple service, which will probably suggest replacing both the mobo and the battery, I try to make a diagnosis myself. From what I can understand, the complete fan indicates a possible problem with a temperature sensor somewhere. The most obvious assumption is the battery, but in fact, Mac Fan Control reports reasonable temperature sensor values ​​(?):

(among others, the image shows a temperature of 27-29 ° C for sensors called Battery Sensor 1/2)

Here are more sensor values ​​of the iStats tool:

Unknown TmOP: 35.25 ° C
Ts0P Palm rest L: 24.75 ° C
TsOS Memory Bank Proximity: -128.0 ° C
Ts1P Unknown: 27.0 ° C
Ts1S Unknown: -128.0 ° C
TAOV Unknown: 25.03 ° C
TBOT Battery TS_MAX: -127.0 ° C
TB1T Battery 1: 27.59 ° C
TB2T Battery 2: 27.0 ° C
Unknown TCaP: 34.69 ° C
GPU TCGC PECI: 39.0 ° C
TCHP Unknown: 37.19 ° C
TCMX Unknown: 39.0 ° C
TCSA PECI SA: 37.0 ° C
TCXC PECI CPU: 39.06 ° C
TCOE CPU 0: 39.09 ° C
TCOF CPU 0: 38.77 ° C
TCOP CPU 0 Proximity: 35.63 ° C
TC1C Core 1: 36.0 ° C
TC2C Core 2: 37.0 ° C
TH0a Unknown: 34.0 ° C
THOF Unknown: 34.03 ° C
TMOP memory location: 36.19 ° C
TPCD platform controller matrix: 36.0 ° C
TSMP Unknown: 33.81 ° C
TUDD Unknown: 32.75 ° C
TWOP AirPort Proximity: 33.94 ° C

This contains some suspicious readings (missing), for TSOs, Ts1S and TBOT. Each does not necessarily mean a material problem.

My main question is: how do I know if only the battery is damaged, or the mobo, or both?
More specific questions:

  1. Can any one provide the output of istats scan for an A1932, or otherwise, confirm that any of these suspicious readings is definitely a problem.
  2. Can any one say where these sensors are (should be) physically located?
