What Our Clients Say…

This is a personal testimonial in favour of Simon Rochester.

I have had the pleasure to work alongside Simon throughout many technical cases with several major accounts during his time at Compaq.

I am extremely sorry to see him leave Compaq. His technical ability as a technical specialist has been most welcomed both by me and my team and also by our Customers.

Simon’s pleasant and cheerful disposition and commitment to ‘making things happen’ along with achieving results is often a welcomed…

I have known Tor for several years and have always found her to be really approachable, friendly and a fantastic ambassador for Rochester & Associates. Tor and her team were able to help me personally recently when a hard disk crash meant that I lost all of my data and use of a business laptop. They had me up and running in no time and nothing was too much trouble for them to sort out.

I have no hesitation in recommending Tor and her team to anyone who needs help with their IT systems – no matte…

Susan ClarksonSusan Clarkson

After a disaster with one of our USB memory sticks (it had practically disintegrated) and fearing we had lost all the data, we were relieved, to say the least, when Rochester & Associates Ltd managed to recover everything on it.

Their ongoing advice has ensured that we have few problems (and certainly no lasting ones) with our IT systems and they have even supplied multiple monitors for our PCs, increasing our productivity tremendously.

We would have no hesitation in recommending Rochester & Ass…

I would like to thank you for your speedy and efficient service following the recent extension to our IT system.

All equipment was supplied on time, as quoted and with the minimum of disruption to our business.

An aspect of your service which I particularly appreciate is the facility to telephone you with any technical ‘niggles’ such as the problem with our colour printer, which you resolved for us in very quick time. This is a most useful service to those of us who are not too technically a…

Bernard ThorntonBernard Thornton

When I needed to purchase a new computer Simon was extremely helpful and honest. He gave me sufficient information to be able to make an appropriate decision.

Since my purchase he has organised the set up and additional training both with himself and Tor. I have always been able to get in touch with Rochester & Associates Ltd whenever I had an urgent problem. As far as I am concerned their customer service is second to none. I cannot recommend them highly enough to anyone who is in need of a com…

Helen WrightHelen Wright

During the time we have been working with Rochester & Associates Ltd they have constantly been both professional and efficient.

We have always found them to be very straightforward when dealing with pressing IT issues and can communicate in plain English technical things that are very complex, even recommending that they don’t do things that may be technically unnecessary.

They are extremely cost effective; their reliability is second to none (they even came to see us on a wet Sunday afternoon!!…

Charlotte BottomleyCharlotte Bottomley

Tor and Simon at Rochester make a great team. With Tor dealing with my IT queries on the phone diagnosing the problem and then getting Simon to come out and fix it.

They don’t laugh at our more basic queries, understand how critical it is that out IT works and also don’t waste money e.g. tell you when a laptop can just do with a clean rather than replacing it.

Moreover they are always enthusiastic and give the impression that they value your custom no matter how small the job.

Electric Cars Failure

So sayeth Simon

On the Feb 23 12

Do BEVs (Battery Electric Vehicle) suffer from a discharging issue that completely ruins the car?

Like the car?

Its a Tesla Roadster, one of a range of BEVs (or Battery Electric Vehicle) currently on the market, and one of the most sexy IMO – you could also try the Nissan Leaf, though it’s not quite as nice looking…

Well, there appears to be a furore over whether or not these cars suffer from a problem with the battery which causes the cars to completely fail – or become ‘Bricked’ (i.e. becomes like a brick read this Urban Dictionary).

From the looks of things there is a problem if the batteries completely discharge for a length of time – those of you with Laptops know this very issue – the battery refuses to recharge resulting in a bricked car.

There are 2 major problems arising from this:

Firstly it’s difficult to tow the offending car to the service centre, as the electric motor is connected directly to the wheels – this means that towing the vehicle results in the motors becoming generators and forcing the batteries to overheat and burn. Low loader then…
Secondly Tesla have been quoting figures like $40,000 USD to replace the batteries in bricked vehicles + the costs of getting the vehicle to them!

In the case of the Tesla it seems that if you don’t charge the car for some time it will become bricked; although this sounds unlikely, imagine parking at an airport for an extended holiday, or in one case, shipping the car to another country.

There is some discussion over the truth of these claims however – some people are lambasting the whistle-blower and saying that this situation is highly unlikely to happen (and both Tesla and Nissan say this is the case) – some people are saying that it’s a problem inherent in the battery technology and is likely to happen.

Personally I’m in the latter camp – eventually all batteries fail, and these are no exception; both Tesla and Nissan have a procedure for replacing them, and of course this service costs £££s. If there isn’t a problem why have a procedure?

I guess the truth will out eventually, but it’s an interesting discussion nonetheless…
