Hi Eleanor, Does the problem go away if you take out the battery and run on the mains adapter instead on its own? I've seen a bad battery short down the mains supply as well. Aedan. -----Original Message----- From: access-uk@xxxxxxxxxxxxx [mailto:access-uk@xxxxxxxxxxxxx] On Behalf Of Eleanor Burke Sent: Sunday, September 25, 2011 8:33 PM To: access-uk@xxxxxxxxxxxxx Subject: [access-uk] Laptop electronic Problem I have a laptop which has developed a severe fault. If I plug in an external keyboard to any of the USB sockets, the machine immediately switches itself off!!! Now if I plug in a thumb drive to any of these USB ports the same thing happens. Apart from telling me to bin it! any suggestions as to what the problem might be. If I let the laptop soldier on, as it is, it is functioning once I do not go to plug-in a peripheral.
