HP and IBM have both announced a series of layoffs as they look to streamline business costs through restructuring, with a total of almost 1,500 jobs set to go.
HP has cut 275 jobs in its webOS business division, following its decision to open source the mobile operating system, and in addition to the announcement in 2010 that 525 jobs were set to go from the division.
HP said it was necessary to make the cuts now that the webOS platform was not a full-part of the company.
"As webOS continues the transition from making mobile devices to open source software, it no longer needs many of the engineering and other related positions that it required before," it said.
"This creates a smaller and more nimble team that is well-equipped to deliver an open source webOS and sustain HP's commitment to the software over the long term.
The firm added that it is working to try and redeploy workers affected by these changes to other roles at the firm.
WebOS was originally developed by Palm, which HP bought in 2010 for $1.2bn.
The firm had hoped webOS would challenge Apple and Google but sales of the webOS-based TouchPad, released last February, did not meet expectations.
Meanwhile, IBM has laid off 1,200 jobs this week, according to the IBM trade union Alliance at IBM, although the firm did not confirm which geographies or divisions are being hit.
"IBM is constantly rebalancing its workforce. That means reducing in some areas and hiring in others - based on shifts in technology and client demand," said an IBM spokeswoman.
"This flexibility allows IBM to remain competitive and relevant in an industry that is constantly changing. And given the competitive nature of our business, we do not publicly discuss the details of our staffing plans."
