Hi can too much potassium cause fluid rention

go google and type in ---potassium and fluid retention---
the first site up states ---it may also benefit heart health (9)
potassium appears to help reduce water retention in two ways, by decreasing sodium levels and increasing u*ine production (10)
bananas , avocados, and tomatoes are examples of foods high in potassium
there are numerous sites that deal with water retention and the affects of potassium
as for your husbands condition, it would be far better to discuss the ongoing swollen knee and ankle and to ask if the potassium would help reduce the condition or would other procedures such as icing the knee when it is hot help reduce the swelling
I mention this because following a knee replacement, there is a lot of swelling in the knee and the specialist demanded an ice pack be used to reduce the heat ( the area around the knee gets hot during the healing process) and reduce the swelling

I have felt heat coming from the pacemaker site from the first day ,,my cardio specialist refuses to test it medically. can you help ?

with the human body anything is possible
If the specialist who fitted the unit will not listen to your concerns , then get a second or third opinion
you can be allergic to the metal used or maybe the installation is not satisfactory
remember that after an operation and cutting of the skin and flesh produces localized heating as it heals
try an ice pack on the wound when it feels hot
following my wife's knee replacement one of the treatments is to cool the knee (which gets very hot) with a cryogenic pack--an ice pack that has cold water in it that is placed on the knee
the heals quicker with it's use than if let as normal with less pain
maybe you have the same result but still talk and get a second opinion

Turns off and freeze automatically for unknown.

if you use your laptop on your knee or cushion you will over heat it causing it to freeze. you need to keep the vents clear ( on bottom and on sides ) check these for dust or blockage. if these are clear use the laptop on a hard surface. if it still gets hot and freezes when it has plenty of air circulating then you will need an expert to reflow the processor or graphics card ( when a laptop gets to hot too often then it melts the solder that holds the chips on the board, they have to be remelted and put back in place )

Why does my projector keep switching itself off?

This sounds like an overheating issue, with the temperature sensor shutting it off when it gets too hot for safety reasons. Assuming this did not start until after you replaced the lamp, my initial guess would be that either the wrong lamp was used, and it's generating more heat than the unit feels comfortable with, or, the temperature sensor itself is going bad.

Laptop gets extremely hot underneath

A hot laptop underneath is normal as long as the laptop is not turning itself off. Also a hot AC Adapter is normal. Some barnds of laptops and chargers (AC Adapters) get hot but if the laptop is functioning don't worry about it.

You can buy a Laptop Cooling Fan which plugs into the USB Port. The laptop sits on top of it and it has fans which help keep the bottom cool. You can get one for less than $20 at:

When the site comes up just put in the white search box at the top of the web page: Laptop Cooling Fan and press GO. When the results are returned you can filter them by Price Low to High.

The link below shows one that I've used to diagnose if a laptop is over heating. The laptop was constantly cutting off unless I would sit it on the cooling fan.

You can also put a lapdesk which is just something that holds the laptop while it is in your lap while in bed or on the sofa For $25

When the site comes up just type: Lapdesk in the search box at the top of the page and press GO.

The link below is for one that is $24.99

Below is a link to one made by Belkin that I found on eBay. My wife uses one like this to sit in bed and watch soap operas all night.

I have a HP tx2120 laptop and it seems to nly turn on once in a blue moon. The power is on but nothing comes up on screen and the underneath gets extremely hot. sometimes when it has been on for about...

this is the problem it needs reflowing. will not boot with this not connecting properly, and leaving this laptop on for long times like this it will shut down as you are cooking the board. and that will damage the board and other parts. might just be a better idea to change the board, if using windows 10 you need to install the original windows with the same windows key that your windows 10 was upgraded with or you will need to buy a new windows key.

If the heat sink air vents are on the underneath of the laptop, they must be kept clear at all times when the laptop is in use. Try using the machine on a hard tray, table or some other type of surface that keeps the vents clear. Sometimes, if you want to use the laptop on your knee, judicious positioning of it to keep the vents clear will sort the problem. If the laptop overheats when used in this manner, switch the laptop off, and try a vacuum cleaner with attachment to clear the debris from the heat sink via the vent holes. DON'T leave the vacuum nozzle on the vent too long, or get it too near the vents otherwise you may damage the fan bearings. Just be careful, and this can often solve the problem. If it's easy to dismantle the underneath to get at the vents this is preferable, but travelmates are notoriously awkward to do this to. Hope this helps. Kind regards

Cloud storage and file storage - DataAlign In vanilla terms, a backup or the process of backing up, refers to the copying and archiving of computer data so it may be used to restore the original after a data loss event. Backups have two distinct purposes. The primary purpose is to recover data after its loss, be it by data deletion or corruption. The simplest definition of a computer backup is an exact copy. In the case of computer files, we are referring to copies of the original files that you have on your laptop, desktop, or external drive. Creating a backup of original content means having that data saved in two places, but it's also important to make sure that those two places aren't on the same type of device. For example, if you have 3 copies of a working document on your computer, if your computer crashes, you will still lose all three. This makes the backup method and medium, an important thing to consider for your backup strategy. With the kind of Online Cloud Backup technology being used these days, it is extremely important to back up your files. Ideally, we store data files, movies, music, photos and our official documents on the computer. With the ever-changing technology, desktops and laptops have reduced in cost, and the quantum of storage inside them has surged considerably over the last few years. Unfortunately, storing all your data in only one place is risky. Accidental deletion, theft, computer loss, natural disaster is just some of the reasons that could cost you heavily as you stand out the chance to lose the data you've spent so long generating and collecting. Having an excellent backup strategy Computer Data Backup is the only way to battle the unexpected loss of data. There is more than one way to back up your computers, and using multiple forms of backup will minimize the risk of losing your valuable files. This is where, the PC Backup solution from DataAlign stands out of the rest and gives a one stop solution for Business Server Data Backup up your computer's data on the secure cloud servers. Our innovative platform has been designed while keeping you in mind. To provide optimal user experience we focus on simplicity and this in turn ensures that you will be able to backup and access large data quickly and smoothly.
